Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a transaction calling method and system based on a whitelist. Background Art

[0002] With the development of science and technology, the construction of information systems, including financial systems, often requires the introduction of new technologies. In order to reduce the risks brought by the introduction of new technologies, it is often necessary to merge the old and new systems. The financial system can adopt a whitelist mechanism to route based on customers. Whitelist customers and non-whitelist customers can be routed to the old and new systems respectively. The current mainstream method is to perform whitelist routing at the gateway or global routing layer and then locate different systems. This method has a strong dependence on gateways or global routing and poor portability. Summary of the invention

[0003] In order to solve the deficiencies of the prior art, the present invention proposes a transaction call method and system based on whitelist routing and application interception. The customer whitelist is realized through the global exchange area and the Cassandra double cache mechanism, and the first system and the second system are run in parallel from the multiple dimensions of the transaction whitelist and the customer whitelist. The transaction call based on the whitelist is realized through the interceptor at the application level, which does not rely on the third-party gateway and load balancing facilities, supports transactions with attachments, and is decoupled from the application implementation logic.

[0004] To achieve the above objectives, the technical solutions adopted by the present invention include:

[0005] A transaction calling method based on a whitelist, wherein a first system platform and a second system platform provide services to the outside at the same time, characterized in that it comprises the following steps:

[0006] Step 1: Register the first system platform and the second system platform in the distributed registration center;

[0007] Step 2: Access the transaction request and obtain the transaction request message;

[0008] Step 3: Get the transaction code from the request message;

[0009] Step 4: Enter the whitelist interceptor of the first system platform to determine whether the transaction code is in the transaction whitelist;

[0010] Step 5: If the customer is in the transaction whitelist, the first system platform is called to process the transaction regardless of whether the customer is in the customer whitelist;

[0011] Step 6: If the customer is not in the transaction whitelist, obtain the customer number information from the message header;

[0012] Step 7: Determine whether the customer number information is in the customer whitelist;

[0013] Step 8: If the customer is in the customer whitelist, the transaction is processed in the second system platform;

[0014] Step 9: If the customer is not in the customer whitelist, the transaction is processed in the first system platform;

[0015] Step 10: Load balance the transaction from the Zookeeper registry center according to the transaction number and forward the http request to the corresponding system platform;

[0016] Step 11: If the forwarding of the http request fails, the error code and error description information related to the forwarding failure are written into the corresponding field of the response message;

[0017] Step 12: Determine whether it is a transaction with attachments;

[0018] Step 13: If the transaction is with attachments, the attachments need to be downloaded from the second system platform to the first system platform through the file transfer service, which can ensure that the access and download functions of the transaction with attachments are normal;

[0019] Step 14: Return a response message.

[0020] Furthermore, executing transaction processing in the first system platform needs to go through the log monitoring interceptor, message conversion interceptor, security interceptor and flow control interceptor processing stack of the original system.

[0021] Furthermore, executing transaction processing in the second system platform of the improved system needs to go through the whitelist interceptor of the original system and the log monitoring interceptor, message conversion interceptor, security interceptor, and flow control interceptor processing stack of the improved system.

[0022] Furthermore, the whitelist interceptor is set at the first layer of the interceptor stack, and access to other interceptor processors of the first system platform can be avoided when calling the second system platform.

[0023] Furthermore, the implementation logic of the whitelist interceptor is encapsulated into an independent jar package. When calling, it is only necessary to introduce the corresponding jar package and add the configuration of the whitelist interceptor to the interceptor stack of the second system platform.

[0024] Furthermore, transactions that are not divided by customer dimension are configured in a transaction whitelist, and the transaction logic is directly processed in the first system platform.

[0025] Furthermore, Zookeeper is used as the distributed registration center.

[0026] Furthermore, the customer whitelist and transaction whitelist are stored in the Cassandra cache of the NoSQL database.

[0027] Furthermore, by querying in Cassandra whether the customer is in the customer whitelist, the transaction access will first be searched from the global exchange area. If not in the whitelist, it will be searched from Cassandra again, and the information on whether the customer is a customer in the customer whitelist will be stored in the global exchange area.

[0032] Whitelist interceptor module, determines whether the transaction code is in the transaction whitelist;

[0033] The registration center module load balances the transaction from the Zookeeper registration center according to the transaction code and forwards the http request to the corresponding system platform;

[0034] The attachment transaction module determines whether it is a transaction with attachments; if it is a transaction with attachments, the attachments are downloaded from the second system platform to the first system platform through the file transfer service.

[0042] Figure 2 This is a schematic diagram of the structure of a transaction calling system based on a whitelist according to the present invention. DETAILED DESCRIPTION

[0043] In order to more clearly understand the content of the present invention, it will be described in detail with reference to the drawings and embodiments.

[0044] like Figure 1 As shown, an embodiment of the present application provides a whitelist-based transaction calling method, in which the first system platform and the second system platform provide services to the outside at the same time, including the following steps:

[0045] Step 1: Register the first system platform and the second system platform in the distributed registration center;

[0046] Step 2: Access the transaction request and obtain the transaction request message;

[0047] Step 3: Get the transaction code from the request message;

[0048] Step 4: Enter the whitelist interceptor of the first system platform to determine whether the transaction code is in the transaction whitelist;

[0049] Step 5: If the customer is in the transaction whitelist, the first system platform will be called to process the transaction regardless of whether the customer is in the customer whitelist;

[0050] Step 6: If the customer is not in the transaction whitelist, obtain the customer number information from the message header;

[0051] Step 7: Determine whether the customer number information is in the customer whitelist;

[0052] Step 8: If the customer is in the customer whitelist, the transaction is processed in the second system platform;

[0053] Step 9: If the customer is not in the customer whitelist, the transaction is processed in the first system platform;

[0054] Step 10: Load balance the transaction from the Zookeeper registration center according to the transaction number, and forward the http request to the corresponding second system platform;

[0055] Step 11: If the forwarding of the http request fails, the error code and error description information related to the forwarding failure are written into the corresponding field of the response message;

[0056] Step 12: Determine whether it is a transaction with attachments;

[0057] Step 13: If the transaction is with attachments, the attachments need to be downloaded from the second system platform to the first system platform through the file transfer service, which can ensure that the access and download functions of the transaction with attachments are normal;

[0058] Step 14: Return a response message.

[0059] The entire transaction implements a series of access processing stacks through the chain of responsibility pattern. Chain of Responsibility is a behavioral design pattern that creates a chain of receiver objects for a request. This pattern gives the type of the request and decouples the sender and receiver of the request. In this pattern, each receiver usually contains a reference to another receiver. If an object cannot handle the request, it will pass the same request to the next receiver, and so on. After the transaction is connected, the interceptors form a linear chain in a certain order. When the transaction processing logic is executed, the interceptors set in the stack will be called according to the order of the stack to perform a series of common processing, including log monitoring, security verification, message conversion, flow control, etc.

[0060] Executing transaction processing in the first system platform requires going through the original system's log monitoring interceptor, message conversion interceptor, security interceptor and flow control interceptor processing stack.

[0061] Executing transaction processing in the second system platform of the improved system needs to go through the whitelist interceptor of the original system and the log monitoring interceptor, message conversion interceptor, security interceptor, and flow control interceptor processing stack of the improved system.

[0062] The so-called whitelist refers to a list of trusted users that are allowed to access or pass verification. Customers on the whitelist are routed to the second system platform, and customers not on the whitelist are routed to the first system platform. The first system platform and the second system platform provide services to the outside world at the same time. The whitelist interceptor is set at the first layer of the interceptor stack, and can avoid accessing other interceptor processors of the first system platform when calling the second system platform.

[0063] The implementation logic of the whitelist interceptor is encapsulated into an independent jar package. When calling, you only need to introduce the corresponding jar package and add the configuration of the whitelist interceptor to the interceptor stack of the second system platform. Add the whitelist interceptor to the first layer of the interceptor stack, so that when you need to call the new system, you can avoid accessing other interceptor processors of the old system, thereby improving transaction performance. It is implemented through java code and can be published as an independent jar package through compilation and packaging. When the application introduces the whitelist interceptor, if it is a maven project, you need to introduce the jar package in the pom file and then deploy and publish it. If it is not a maven project, just put the jar package in the lib directory of the project. The transaction interception of the application is implemented in a responsibility chain mode, and the general processing of the lower interceptor is executed after the general processing of the upper interceptor is executed. In this patent, the whitelist interceptor needs to be introduced into the interceptor stack of the old system in the form of JavaBean and is located in the first layer of the interceptor stack. The advantage of placing it in the first layer is that the processing logic of subsequent interceptors is avoided, which improves performance. When the application starts, the interceptor will be loaded into memory for use in transactions.

[0064] Transactions that are not divided by customer dimension are configured in the transaction whitelist, and the transaction logic is processed directly in the first system platform.

[0065] Zookeeper is a distributed, open source distributed application coordination service and an open source implementation of Google's Chubby. It is a software that provides consistency services for distributed applications, and the functions provided include configuration maintenance, domain name services, distributed synchronization, group services, etc. Zookeeper is a common technology for implementing a distributed registration center. The present invention uses Zookeeper as a distributed registration center. Both the first platform system and the second platform system need to be registered in the Zookeeper registration center. When the application starts, the basic information of the application (including the URL request address) will be registered in the Zookeeper registration center. After the application stops, the application will be removed from the Zookeeper registration center.

[0066] In addition, this solution also supports the replacement and transformation of the load balancing algorithm through other registration center components.

[0067] The customer whitelist and transaction whitelist are stored in the Cassandra cache of the NoSQL database.

[0068] NoSQL refers to a non-relational database. It does not guarantee the ACID (atomicity, consistency, isolation, and persistence) characteristics of relational data, but it is easy to expand and has high performance, making it suitable for scenarios with high system performance requirements. Cassandra is a hybrid non-relational database with the characteristics of distribution, high scalability, flexible mode, and column-based structuring. Cassandra is a NOSQL database, and the whitelist is stored in Cassandra. The structure of the whitelist table includes three fields: id, type, and targetid. The value of id is a specific customer number, type is a fixed value, such as 99, and targetid can be set to 1. If there is a data record in the whitelist table with type 99 and id as a customer number, it means that the customer is in the whitelist; otherwise, the customer is not in the whitelist. Before the application is started, the whitelisted customers involved will be loaded into Cassandra by executing scripts for subsequent application calls.

[0069] By querying whether the customer is in the customer whitelist in Cassandra, the transaction access will first be searched in the global exchange area. If not in the whitelist, it will be searched in Cassandra again, and the information on whether the customer is a customer in the customer whitelist will be stored in the global exchange area.

[0070] If an exception occurs when the second system platform is called, the error code and error description of the response need to be set in the response message so that the user can get the expected return result.

[0071] A transaction calling system based on a whitelist, comprising:

[0072] A platform registration module registers the first system platform and the second system platform in a distributed registration center;

[0073] Transaction request module, receiving transaction request and obtaining transaction request message;
