Description

Technical Field

[0001] The embodiments of the present invention relate to the field of automatic programming, and more particularly to a method, apparatus, device and storage medium for processing reverse transactions. Background Technology

[0002] With the continuous advancement of computer technology, financial services are becoming increasingly diversified, and their reliance on online transactions is deepening. Therefore, the processing of online transactions has become particularly important.

[0003] After an online transaction occurs, due to certain technical or business reasons, it may be necessary to reverse the original transaction, that is, to reverse the original transaction. When processing reversed and positive transactions, it is usually broken down into multiple transactions. For example, the channel access transaction part records the transaction status when the caller accesses the channel; the external call transaction part records the transaction status of the external components when making an external call; and the local logic transaction part records the transaction part of local logic processing. The specific reversal is then performed through the above multiple transaction information.

[0004] However, this method of reversing transactions requires that the reversal transaction request include complete transaction information, and the amount of data to be processed is extremely large. The reversal time is long, and there is also a risk of inconsistency between the transaction information of different parts. It is not flexible enough to support complex business logic. Summary of the Invention

[0005] This invention provides a method, apparatus, device, and storage medium for processing reversal transactions, in order to respond to reversal transaction requests based on positive transaction flow information.

[0006] In a first aspect, embodiments of the present invention provide a method for processing reversal transactions, including:

[0007] When a reversal transaction request is received, it is determined whether there is positive transaction flow information that matches the reversal transaction request;

[0008] If it is determined that there is positive transaction flow information that matches the reversal transaction request, then the reversal transaction request is responded to based on the positive transaction flow information;

[0009] Record the reverse transaction flow information and associate it with the positive transaction flow information.

[0010] Secondly, embodiments of the present invention provide a processing apparatus for reversal transactions, comprising:

[0011] The positive transaction flow information judgment module is used to determine whether there is positive transaction flow information that matches the reverse transaction request when a reverse transaction request is obtained;

[0012] The reverse transaction request response module is used to respond to the reverse transaction request based on the positive transaction flow information if it is determined that there is positive transaction flow information that matches the reverse transaction request.

[0013] The associated execution module is used to record the reverse transaction flow information and associate it with the positive transaction flow information.

[0014] Thirdly, embodiments of the present invention also provide an electronic device, the electronic device comprising:

[0015] One or more processors;

[0016] Storage device for storing one or more programs;

[0017] When the one or more programs are executed by the one or more processors, the one or more processors implement the reversal transaction processing method described in any embodiment of the present invention.

[0018] Fourthly, embodiments of the present invention also provide a storage medium containing computer-executable instructions, which, when executed by a computer processor, implement the reversal transaction processing method described in any embodiment of the present invention.

[0019] The technical solution provided by this invention, when a reversal transaction request is received, responds to the reversal transaction request based on the positive transaction flow information matching the reversal transaction request, and records the reversal transaction flow information and the correlation between the reversal transaction flow information and the positive transaction flow information. This means that the reversal transaction request does not need to include complete transaction information, reducing the amount of transaction data to be processed, shortening the processing time of the reversal transaction, and avoiding the occurrence of inconsistencies in multiple internal transaction information. At the same time, executing the reversal transaction based on the stored positive transaction flow information also provides sufficient data support for complex business processing logic.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention and not the entire structure.

[0026] Example 1

[0027] Figure 1 This is a flowchart of a method for processing reversal transactions according to Embodiment 1 of the present invention. This embodiment is applicable to processing reversal transactions based on positive transaction flow information. This method can be executed by the reversal transaction processing device in this embodiment of the present invention. This device can be implemented by software and / or hardware and can be integrated into a terminal device or server. Typically, it can be integrated into the server of a distributed and microservice-based banking business system. The method specifically includes the following steps:

[0028] S110. When a reversal transaction request is obtained, determine whether there is positive transaction flow information that matches the reversal transaction request.

[0029] A positive transaction represents a positive transaction logic, a type of transaction carried out to achieve a certain business effect; for example, if account A transfers 100 yuan to account B, then 100 yuan is deducted from account A and 100 yuan is added to account B, which is a positive transaction. A reverse transaction is the reverse of a positive transaction, and its purpose is to remove the positive transaction. Taking the above positive transaction as an example, returning the deducted 100 yuan to account A and deducting the added 100 yuan from account B is a reverse transaction.

[0030] A reversal request can include a request initiated by the transaction initiator to cancel a positive transaction after it has been completed. For example, Account A, after executing a transfer transaction and receiving feedback from the banking system confirming the successful transfer, requests to cancel the transaction. It can also include a reversal request initiated by the transaction initiator's terminal device when it detects an anomaly in the positive transaction. For example, the positive transaction has been marked as successful on the terminal device, but the transaction package sent to the banking system has not received a response (i.e., the transaction timed out). Without certainty that the transaction was successfully completed on the banking system, the terminal device, to ensure the user's interests, resends a request to the banking system to cancel the transaction.

[0031] Transaction information is recorded in the business system's database and includes business information involved in the transaction process, such as the transaction parties (i.e., the transaction initiator and the transaction responder) and the transaction type (e.g., deposit, withdrawal, income, expenditure). When the bank's business system processes a positive transaction request, it records the transaction information for that positive transaction. Therefore, if the positive transaction information is retrieved from the database, it also indicates that the positive transaction has been completed.

[0032] Optionally, in this embodiment of the invention, the positive transaction log information includes key-value information; the key-value information includes a legal entity identifier, a global event tracking number, a sub-transaction sequence number, and a transaction direction identifier. When the bank's business system completes the processing of a positive transaction and registers the positive transaction log information, it stores the key-value information in the positive transaction log information in a key-value database. Utilizing the fast access speed and high query efficiency of the key-value database, it achieves rapid matching between reversal and positive transactions. Compared to querying data from a relational database, this improves the efficiency of obtaining relevant data for positive transactions and increases the matching speed between reversal and positive transactions.

[0033] The legal entity identification document (Identity document) is used to identify a specific organization and distinguish business processes, user interfaces, and data. The Legal Entity ID is reflected in system data flow and data storage and can be represented by a 5-digit code consisting of two segments (country or region code + legal entity code), serving as the legal entity identification information during the transaction process. The Global Event Tracking Number (GAN) is a globally unique identifier generated when a transaction is triggered. This identifier is shared throughout the entire transaction process as the transaction identity, thus connecting the entire transaction line from the transaction initiator to the transaction service processing end. The number of digits in the GNA can be set as needed, for example, it can be set to 25 digits. The Sub-Transaction Sequence Number is used to distinguish the internal number of each transaction node. The number of digits in the Sub-Transaction Sequence Number can also be set as needed, for example, it can be set to 10 digits. For combined transactions, the sub-transaction sequence number is modified by the combination points between each transaction; for non-combined transactions, the sub-transaction sequence number is all 0. The global event tracking number can uniquely locate a transaction, and within that transaction, the specific transaction node can be determined by the sub-transaction sequence number. The transaction direction identifier indicates whether the transaction is a positive or negative transaction; if it is a positive transaction, the transaction direction identifier is 0, and if it is a negative transaction, the transaction direction identifier is 1. Key-value information can also include a logical partition number, represented in the form of "license plate number + reverse identifier". The license plate number is related to the business date of the transaction, and the reverse identifier is the reverse of a specified number of digits of the global event tracking number. For example, the logical partition number is represented by a 2-digit license plate number plus the last 3 digits of the global event tracking number in reverse order.

[0034] Specifically, determining whether there is positive transaction flow information matching the reversal transaction request includes: parsing the reversal transaction request to obtain the transaction identifier of the positive transaction matching the reversal transaction request; wherein, the transaction identifier includes a global event tracking number and a sub-transaction sequence number; and determining whether there is positive transaction flow information matching the reversal transaction request based on the transaction identifier of the positive transaction. Parsing the reversal transaction request only requires obtaining the global event tracking number and sub-transaction sequence number of the corresponding positive transaction, and the existence of positive transaction flow information matching the reversal transaction request can be determined based on the above information.

[0035] Optionally, in this embodiment of the invention, the positive transaction log information further includes VARCHAR field information in a data table; the VARCHAR field information in the data table includes a data length bit, a region flag bit, a request message area, a response message area, and / or an application scenario area; the data length bit is used to record the length of the VARCHAR field information in the data table; the region flag bit is used to record whether the requested message area, the response message area, and the application scenario area exist; the request message area is used to record the request message header and the request message body; the response message area is used to record the response message header and the response message body; and the application scenario area is used to record the calling logic of the application component. VARCHAR is a flexible data type used to store character data. Compared to traditional CHAR character data, VARCHAR can store variable-length strings and occupies less storage space. The VARCHAR field information in a data table is the data content stored in the data table of a relational database. The request message area, response message area, and application scenario area all store data in JSON string format, and the areas are separated by "#@@#". Specifically, the request message area and response message area store all message information for the transaction, including the global event tracking number and sub-transaction sequence number. Therefore, based on the global event tracking number and sub-transaction sequence number of the matching positive transaction, the matching VARCHAR field information of the data table can be obtained from the relational database.

[0036] Optionally, in this embodiment of the invention, the key-value information further includes a sequence number; the sequence number is related to the length of the VARCHAR field information in the data table. The VARCHAR data type has a maximum allowed string length (e.g., set to 12KB). If the amount of data in the VARCHAR field information of the data table is too large, exceeding the maximum length, it needs to be split into multiple data entries. The number of these split entries can be represented by a sequence number in the key-value information to reflect the association between the key-value information and the VARCHAR field information in the data table.

[0037] S120. If it is determined that there is positive transaction flow information that matches the reversal transaction request, then respond to the reversal transaction request according to the positive transaction flow information.

[0038] If a positive transaction log information matching the reversal transaction request exists, the processing logic can be reversed based on the processing logic of the positive transaction recorded in the database to respond to the reversal transaction. Alternatively, the calling logic of each application component (i.e., a functional module with transaction processing capability) involved in the transaction can be reversed through the application scenario area recorded in the data table in the above technical solution to process the reversal transaction. For example, during a positive transaction, application component A calls application component B, application component C, and application component D in sequence. Then, during a reversal transaction, application component A needs to call application component D, application component C, and application component B in sequence.

[0039] If the reversal transaction request includes a complete request message, the specific message object can be directly obtained by parsing the reversal transaction request. However, to facilitate initiating reversal transactions, especially when external systems (e.g., transaction business systems of other financial institutions) initiate reversal transaction requests to the current transaction business system, the external system may not store the specific transaction business data in the request message. Therefore, the request message of the external system may not contain a message entity field, but only the global event tracking number and sub-transaction sequence number of the matching positive transaction. Therefore, the request message object of the reversal transaction can be obtained by reading the request message of the positive transaction stored in the database. Specifically, responding to the reversal transaction request based on the positive transaction flow information includes: generating the reversal transaction request message based on the request message of the positive transaction matching the reversal transaction request; and responding to the reversal transaction request based on the reversal transaction request message. When a request message for a positive transaction is received, the Java object is converted into a JSON string for storage. When the stored information is read, the JSON string is converted back into a Java object. This avoids the tedious mapping and parsing of XML request messages, improving the storage and retrieval efficiency of transaction messages.

[0040] Optionally, in this embodiment of the invention, the application scenario area records the calling logic of application components through a runtime stack. The runtime stack is the stack relationship of the current application component calls, mainly recording the nesting level of the current application component; for example, when application component A calls application component B, application component B is pushed onto the stack, and the stack relationship of the application components called in this transaction is A+B; when application component B completes its call and returns to application component A, the stack relationship is A; to ensure the uniqueness of the stack relationship of application component calls, when an application calls the same application component multiple times at the same nesting level, the sequence number of the application component being called must be specified; taking the calling logic of application components in a transaction recorded in Table 1 as an example...

[0041] Table 1

[0042]

[0043]

[0044] The transaction entry point is application component A. Application component A first calls (CALL) application component B. Within application component B, the transaction sequentially calls application components C, D, and C. Specifically, when the transaction enters application component A, the nesting level is 1, and the stack relationship is A(01). When application component A calls application component B, the transaction enters application component B, and the nesting level is 2, with a stack relationship of A(01)+B(01). When application component B calls application component C for the first time, the transaction enters C, and the nesting level is 3, with a stack relationship of A(01)+B(01)+C(01). When application component C returns (GOBACK), the transaction returns to application component B, and the nesting level is 2, with a stack relationship of A(01)+B(01). When application component B calls... Using application component D, after the transaction enters D, the nesting level is 3, and the stack relationship is A(01)+B(01)+D(01). When application component D returns, the transaction returns to application component B, and the nesting level is 2. The stack relationship of the module call is A(01)+B(01). When application component B calls application component C for the second time, after the transaction enters application component C, the nesting level is 3, and the stack relationship is A(01)+B(01)+C(02). The stack relationship at this time is different from that of application component B's first call to application component C (the numbers 01 and 02 in parentheses represent the first and second calls, respectively). When application component C returns, the transaction returns to application component B, and the nesting level is 2. When application component B returns, the transaction returns to application component A, and the nesting level is 1.

[0045] In particular, in this embodiment of the invention, the execution logic of the application component can be directly implemented by executing code. Compared with implementation through configuration, configuration can only realize simple call flow and simple interface transmission. However, in microservice-based business systems, the call relationship for handling transactions is more complex, and most of the interface fields during the call come from calculation and database access. Implementation directly through executing code can better meet the complex call logic.

[0046] S130. Record the reverse transaction flow information and associate it with the positive transaction flow information.

[0047] When processing a reversal transaction request, the transaction flow information is recorded in a database. The reversal transaction flow information and the corresponding positive transaction flow information can be associated with specific identifiers. For example, in each database, the same association identifier is set for the reversal transaction and its corresponding positive transaction to mark the association relationship between the reversal transaction and the positive transaction. Furthermore, the global event tracking number of the previous transaction of the reversal transaction can be set as the global event tracking number of the matching positive transaction, and the sub-transaction sequence number of the previous transaction of the reversal transaction can be set as the sub-transaction sequence number of the positive transaction. Similarly, the global event tracking number of the next transaction of the positive transaction can be set as the global event tracking number of the reversal transaction, and the sub-transaction sequence number of the next transaction of the positive transaction can be set as the sub-transaction sequence number of the reversal transaction. The global event tracking number and sub-transaction sequence number of the reversal transaction are generated during the processing of the reversal transaction, following the same process as generating the global event tracking number and sub-transaction sequence number of the positive transaction during the processing of the positive transaction.

[0048] The technical solution provided by this invention, when a reversal transaction request is obtained, responds to the reversal transaction request based on the positive transaction flow information matching the reversal transaction request, and records the reversal transaction flow information and the correlation between the reversal transaction flow information and the positive transaction flow information. This means that the reversal transaction request does not need to include complete transaction information, reducing the amount of transaction data to be processed, shortening the processing time of the reversal transaction, and avoiding the occurrence of inconsistencies in multiple internal transaction information. At the same time, executing the reversal transaction based on the stored positive transaction flow information also provides sufficient data support for complex business processing logic.

[0049] Example 2

[0050] Figure 2This is a flowchart of a method for processing a reversal transaction according to Embodiment 2 of the present invention. This embodiment is a specific implementation based on the above technical solution. In this embodiment, the positive transaction flow information includes fixed field information of a data table. Before responding to the reversal transaction request based on the positive transaction flow information, the method further includes: comparing the request message of the reversal transaction with the fixed field information of the matching positive transaction data table. Specifically, the method includes the following steps:

[0051] S210. When a reversal transaction request is obtained, determine whether there is positive transaction flow information that matches the reversal transaction request; wherein, the positive transaction flow information includes fixed column information of the data table.

[0052] The fixed fields in the data table include identification information, institutional information, and account identity information; the identification information includes transaction code, service type, system time, global event tracking number, and / or sub-sequence transaction number; and / or the institutional information includes transaction institution, transaction teller, transaction channel, and / or business date; and / or the account identity information includes transaction master account, transaction counterparty account, free trade zone attribute of transaction master account, and / or free trade zone attribute of transaction counterparty account. Fixed field information in a data table refers to the data content stored in fixed fields within a relational database table. Among these, "Service Type" is a coded information describing the transaction type, including a transaction field indicating whether the transaction is a positive or negative transaction. For example, a service type identifier is a 6-digit number, with the fourth digit being the transaction field; a fourth digit of 0 indicates a positive transaction, and a fourth digit of 1 indicates a negative transaction. The transaction code also serves as a unique identifier for each transaction in the database. "Transaction Channel" refers to the specific method of implementing the transaction, such as over-the-counter, online banking, or ATM. "Transaction Institution" refers to the region and branch where the transaction occurred. "Transaction Teller" is the staff member handling the transaction. "Business Date" is the time the transaction occurred.

[0053] S220. If it is determined that there is positive transaction flow information that matches the reversal transaction request, the request message of the reversal transaction is compared with the fixed column information of the data table of the matching positive transaction.

[0054] S230. If the request message for the reverse transaction is consistent with the fixed field information of the data table of the positive transaction, then respond to the reverse transaction request according to the request message for the reverse transaction.

[0055] Since the reversal transaction request message is obtained by directly parsing the reversal transaction request or by parsing the request message from the VARCHAR field information of the positive transaction data table, to ensure the accuracy of the obtained reversal transaction request message, a consistency comparison is performed between the reversal transaction request message and the fixed field information of the positive transaction data table. For example, the transaction code, trading institution, and trading teller in the reversal transaction request message are compared with the same items in the fixed field information of the positive transaction data table to determine if they are consistent; the business date of the reversal transaction is compared with the business date in the fixed field information of the positive transaction data table. If the dates are consistent, or if the reversal transaction... If the transaction date is one day earlier than the original transaction date, and the reversal transaction occurs within a preset time (e.g., two hours) after the original transaction date changes, then the request message for the original transaction is considered consistent with the fixed field information in the data table of the original transaction. This mechanism stipulates that the reversal transaction must be performed on the same day as the original transaction or completed within a certain period after the date change, so that when the previous day's transaction records are archived daily after the specified time, the previous day's transaction records are already in their final state and will not have their fields modified due to the reversal transaction. If the request message for the reversal transaction is inconsistent with the fixed field information in the data table of the original transaction, a transaction alarm message is issued to indicate that the reversal transaction is abnormal.

[0056] S240. Record the reverse transaction flow information and associate it with the positive transaction flow information.

[0057] The technical solution provided by this invention, when it is determined that there is positive transaction flow information that matches the reversal transaction request, compares the reversal transaction request message with the fixed field information of the data table of the matching positive transaction, and responds to the reversal transaction request when the match is consistent, thus ensuring the accuracy of the reversal transaction request message and improving the security of the reversal transaction.

[0058] Example 3

[0059] Figure 3 This is a flowchart of a method for processing a reversal transaction according to Embodiment 3 of the present invention. This embodiment is a specific implementation based on the above technical solution. In this embodiment, if it is determined that there is no positive transaction flow information matching the reversal transaction request, pseudo positive transaction flow information is inserted, and when a positive transaction request matching the reversal transaction request is obtained, the positive transaction request is not responded to. Specifically, the method includes the following steps:

[0060] S310. When a reversal transaction request is obtained, determine whether there is positive transaction flow information that matches the reversal transaction request.

[0061] S320. If it is determined that there is no positive transaction flow information matching the reversal transaction request, then insert pseudo positive transaction flow information and respond to the reversal transaction request according to the pseudo positive transaction flow information.

[0062] As described in the above technical solution, when an anomaly occurs in a positive transaction, such as a timeout, a reversal transaction request arrives before the positive transaction request. At this time, the positive transaction request is not processed, and the transaction log information for that positive transaction does not exist in the database. Inserting pseudo-positive transaction log information provides an execution basis for the reversal transaction, ensuring the smooth execution of the reversal transaction request. That is, the reversal transaction request is processed based on the pseudo-positive transaction log information, ensuring that the transaction caller (i.e., the transaction initiator) receives feedback information indicating a successful reversal. Furthermore, the pseudo-positive transaction log information is not real transaction information but rather transaction log information temporarily constructed based on the reversal transaction request, and will not affect other real transactions. The key-value information in the pseudo-positive transaction log can be directly constructed based on the key-value information of the positive transaction obtained from the reversal transaction request. That is, the key-value information in the pseudo-positive transaction log is the same as the key-value information in the real positive transaction log. However, the VARCHAR field information and fixed field information of the data table in the pseudo-positive transaction log are blank. It is equivalent to the reversal transaction and the pseudo-positive transaction being completely empty except for the key-value information that determines their mutual matching. The reversal transaction reverses a blank positive transaction and can return a reversal success feedback message to the transaction caller, but in fact, the reversal transaction is not actually completed.

[0063] S330. When a positive transaction request matching the reversal transaction request is obtained, the positive transaction request is marked as processed, and the positive transaction request is refused to be responded to.

[0064] Since the reversal transaction has been processed and a successful reversal feedback message has been returned to the transaction caller, but the reversal transaction has not actually been executed, when a matching positive transaction request is obtained, it is also not processed. Accordingly, neither the positive transaction request nor the reversal transaction request is processed, which is consistent with the result of processing both positive transaction requests and reversal transaction requests. It is not affected by the positive transaction timeout and does not affect the transaction processing efficiency of the system. At the same time, the transaction caller can obtain the successful reversal feedback message.

[0065] The technical solution provided by this invention inserts pseudo-positive transaction information when it is determined that no positive transaction information matches the reversal transaction request. Based on the pseudo-positive transaction information, the reversal transaction request is responded to. When a positive transaction request matching the reversal transaction request is obtained, the positive transaction request is refused to be responded to. This ensures that when a positive transaction times out, it does not affect the transaction processing efficiency of the system. The transaction caller can obtain feedback information that the reversal was successful. The transaction processing result in the system is also consistent with the result of processing both the positive transaction request and the reversal transaction request.
