Description

Technical Field

[0001] The present invention relates to computer technology, and in particular to a multi-mode business processing method, device and equipment. Background Art

[0002] A distributed business system can process distributed business. The distributed business system includes multiple sub-business systems. The distributed business includes multiple sub-businesses. One sub-business system is usually used to process one sub-business.

[0003] At present, the sub-business system can be a SAGA mode or a Try-Confirm-Cancel (TCC) mode for processing long-lived transactions. When processing distributed business, the distributed business processing system needs to ensure that the processing results of each sub-business in the distributed business are consistent, that is, either each sub-business is processed successfully, or each sub-business fails to be processed. In the related art, in order to ensure the consistency of the processing results of each sub-business in the distributed business, it is necessary to set the mode of each sub-business system in the distributed business system to the same mode. If the modes of each sub-business system in the business system are different, it is impossible to ensure that the processing results of each sub-business in the distributed business are consistent, which leads to poor reliability of business processing.

[0068] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0070] To facilitate understanding, the concepts involved in the embodiments of the present application are first described in detail.

[0071] TCC mode: TCC mode includes three types of processing, namely pre-processing, execution processing and rollback processing. Among them, pre-processing refers to the try operation (try operation), execution processing refers to the confirmation operation (Confirm operation), and rollback processing refers to the cancel operation (Cancel operation). The following describes the three types of processing in TCC mode respectively.

[0072] Preprocessing: Preprocessing can usually include inspection processing and business resource allocation processing. Inspection processing is used to check whether the business request meets the business requirements of the sub-business system. For example, assuming that the business request is a request to deduct an amount of 1 from account 1, the inspection processing may include: determining whether account 1 exists, determining whether the password of account 1 entered by the user is correct, and whether the current balance in account 1 is greater than the amount 1. Business resource allocation processing is used to allocate the resources required for execution processing to the sub-business system to ensure that the result of the execution processing is a successful execution. For example, assuming that the business request is a request to deduct an amount of 1 from account 1, the business resource allocation processing may include: freezing the amount of 1 in account 1 to ensure that the amount of 1 can be successfully deducted from account 1 in subsequent execution processing.

[0073] Execution processing: Execution processing is used to complete business logic processing. For example, if the business request is to deduct an amount of 1 from account 1, then execution processing can achieve the deduction of an amount of 1 from account 1. In TCC mode, if preprocessing is successful, execution processing must be successful.

[0074] Rollback processing: It is used to roll back the processing that has been executed when the preprocessing or execution processing fails, so as to cancel the operation that has been performed and release the business resources allocated in the preprocessing stage.

[0075] SAGA mode: SAGA mode is a distributed transaction implementation mode based on compensation transactions. In SAGA mode, the distributed business includes several sub-businesses, each of which corresponds to business processing and reverse business processing. Business processing can also be called forward business processing, and reverse business processing can also be called reverse compensation processing. When the distributed business of SAGA mode is executed, the forward business processing of each sub-business is executed in turn. If the forward business processing of all sub-businesses is successfully executed, the distributed business execution is completed. If the forward business processing of any sub-business fails to execute, the reverse business processing (reverse compensation processing) is performed on the sub-business that has already performed the forward business processing, so that the sub-business that has already performed the forward business processing returns to the initial state.

[0076] Business consistency of distributed business: A distributed business includes multiple sub-businesses. Business consistency means that the processing results of each sub-business are the same. The processing results of the multiple sub-businesses are either all executed successfully or all executed failed.

[0077] Next, combine Figure 1 , the distributed business system involved in the embodiments of the present application is described.

[0078] Figure 1 This is an architecture diagram of the distributed business system provided in the embodiment of this application. Figure 1 , the distributed business system includes a business manager and multiple sub-business systems. Distributed business includes multiple sub-businesses, and a sub-business system can be used to process a sub-business. The business manager is used to call and manage the sub-business system to ensure that the processing results of each sub-business system for its corresponding sub-business are consistent. A sub-business system can be deployed in a virtual machine, and different virtual machines can be deployed on the same physical device or on different physical devices. The business manager can be deployed on the same physical device as the sub-business system, or on a different physical device.

[0079] Optionally, if the sub-business system is in TCC mode, the sub-business system may include three interfaces: an interface for preprocessing, an interface for execution processing, and an interface for rollback processing. Accordingly, the business manager may call the interface of the sub-business system to enable the sub-business system to perform preprocessing, execution processing, or rollback processing.

[0080] Optionally, if the sub-business system is in SAGA mode, the sub-business system may include two interfaces: an interface for business processing and an interface for reverse business processing. Accordingly, the business manager may call the interface of the sub-business system to enable the sub-business system to perform business processing or reverse business processing.

[0081] In the related art, if the modes of the sub-business systems in the business system are different, that is, the modes of the sub-businesses included in the distributed business are different, it is impossible to ensure that the processing results of the sub-businesses in the distributed business are consistent, that is, the business consistency of the distributed business cannot be guaranteed, which leads to poor reliability of business processing.

[0082] In order to solve the above technical problems, in the embodiment of the present disclosure, if the distributed service includes the sub-service of the TCC mode and the sub-service of the SAGA mode, the sub-service of the TCC mode can be pre-processed first, and then the sub-service of the SAGA mode can be processed after the pre-processing of the sub-service of the TCC mode is successful. If the execution result of the sub-service of the SAGA mode is successful, the sub-service of the TCC mode is executed. Since the sub-service of the TCC mode has been pre-processed, the execution of the sub-service of the TCC mode will definitely be successful, thereby ensuring the consistency of the service processing. If the execution result of the sub-service of the SAGA mode is failure, the sub-service of the TCC mode is rolled back to roll back the sub-service of the TCC mode to the initial state. Therefore, the execution of the sub-service of the TCC mode is also failed, thereby ensuring the consistency of the service processing.

[0083] The following specific embodiments are used to describe the technical solutions shown in the present application in detail. The following embodiments can exist independently or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

[0084] Figure 2 A flowchart of a multi-mode service processing method provided in an embodiment of the present application. Figure 2 , the method may include:

[0085] S201: Obtain a business processing request.

[0086] The execution subject of the embodiment of the present application may be a distributed business system. Some steps in the embodiment of the present application may be executed by a business manager in the distributed business system, and some steps may be executed by the business manager calling a sub-business system.

[0087] Optionally, a business manager in the distributed business system may obtain the business processing request.

[0088] The service processing request is used to request processing of a first service, the first service includes at least one first sub-service and at least one second sub-service, and the first sub-service and the second sub-service have different modes. The mode of the first sub-service is TCC mode, and the mode of the second sub-service is SAGA mode.

[0089] The business processing request may be a business processing request from a client. For example, the business processing request may be a request to transfer a predetermined amount in account 1 to account 2. Assuming that the business processing request corresponds to a first business, the first business includes the following two sub-businesses: sub-business 1: deducting a predetermined amount from account 1, and sub-business 2: depositing a predetermined amount into account 2.

[0090] S202: Preprocess each first sub-service respectively.

[0091] Optionally, after the service manager obtains the service processing request, the service manager may call corresponding sub-service systems respectively, so that the sub-service systems process the corresponding first sub-service.

[0092] The preprocessing is used to ensure that the result of executing the first sub-service is successful, that is, if the preprocessing of the first sub-service is successful, the execution of the first sub-service will also be successful.

[0093] Preprocessing may include inspection processing and allocation processing of business resources, and the inspection processing is used to detect whether the business parameters in the business processing request meet the business requirements corresponding to the first sub-business. The allocation processing of business resources is used to divide the business resources required for executing the first sub-business. If the inspection processing of the first sub-business is successful, and the allocation processing is successful, the preprocessing of the first sub-business is successful. After the preprocessing of the first sub-business is successful, the first sub-business has met the necessary conditions for the successful execution processing. Therefore, after the preprocessing of the first sub-business is successful, it is assumed that the execution processing of the first sub-business must also be successful.

[0094] The process of preprocessing each first sub-business is the same. The following is an explanation of the process of preprocessing any first sub-business: obtaining business parameters corresponding to the first sub-business in the business processing request, determining whether the business parameters meet the business requirements corresponding to the first sub-business (inspection processing), and when it is determined that the business parameters meet the business requirements corresponding to the first sub-business, allocating business resources to the first sub-business, and the business resources are the resources required to execute the first sub-business (business resource allocation processing).

[0095] For example, assuming that the first sub-service is: deducting a preset amount from account 1, the service request may include account 1, the password of account 1, and the preset amount, and the check process may include: checking whether account 1 exists, checking whether the password of account 1 is correct, and checking whether the amount in account 1 is greater than or equal to the preset amount. The allocation process of service resources may include: freezing the preset amount in account 1.

[0096] Optionally, at least one first sub-service may be preprocessed in parallel or sequentially. For example, a processing sequence of at least one first sub-service may be obtained, and the at least one first sub-service may be preprocessed according to the processing sequence.

[0097] S203: If the pre-processing of the at least one first sub-service is successful, perform service processing on the at least one second sub-service to obtain a second execution result corresponding to the at least one second sub-service.

[0098] The service manager may determine whether the preprocessing of the first sub-service is successful. After the service manager determines that the preprocessing of at least one first sub-service is successful, the service manager may call the corresponding sub-service system so that the sub-service system performs service processing on the corresponding second sub-service.

[0099] If the pre-processing of each first sub-service is successful, then service processing is performed on at least one second sub-service.

[0100] The second execution result corresponding to the at least one second sub-business can be obtained by performing business processing on at least one second sub-business in the following manner: determining the execution order of at least one second sub-business, and performing business processing on at least one second sub-business according to the execution order, until each second sub-business is executed successfully, and determining the second execution result as successful execution, or until it is determined that the execution of any second sub-business in the at least one second sub-business fails, and determining the second execution result as failed execution.

[0101] For example, assuming that at least one second sub-business includes sub-business 1, sub-business 2, sub-business 3 and sub-business 4, and the execution order of the four sub-businesses is: sub-business 1, sub-business 2, sub-business 3 and sub-business 4, the four sub-businesses can be processed in sequence. Assuming that the business processing of the four sub-businesses is successful, the second execution results corresponding to the four sub-businesses are successful execution. Assuming that the business processing of sub-business 1 and sub-business 2 is successful, and the business processing of sub-business 3 fails, the business processing of sub-business 4 will no longer continue, and the second execution result is determined to be execution failure. After determining that the execution of the second execution result has failed, reverse business processing can be performed on sub-business 1 and sub-business 2 to make sub-business 1 and sub-business 2 roll back to the initial state (the state before business processing). If part of the business processing is also performed on sub-business 3, the part of the business processing that has been performed in business 3 is also rolled back.

[0102] For any second sub-service, the state of the second sub-service after the reverse service processing is the same as the state of the second sub-service before the service processing.

[0103] S204: Perform execution processing or rollback processing on each first sub-service according to the second execution result, and obtain a first execution result corresponding to each first sub-service.

[0104] The first execution result is the same as the second execution result, the first execution result and the second execution result are both successful, or the first execution result and the second execution result are both failed.

[0105] If the second execution result is successful, each first sub-business is executed separately to obtain the first execution result corresponding to each first sub-business, and the first execution result corresponding to each first sub-business is successful. In this case, both the first execution result and the second execution result are successful.

[0106] If the second execution result is execution failure, each first sub-service is rolled back to obtain the first execution result corresponding to each first sub-service, and the first execution result corresponding to each first sub-service is execution failure. In this case, both the first execution result and the second execution result are execution failures.

[0107] The first sub-service may be rolled back in the following manner: roll back pre-processing of the first sub-service to obtain a first execution result corresponding to the first sub-service, wherein the state of the first sub-service after rollback is the same as the state of the first sub-service before pre-processing.

[0108] exist Figure 2In the illustrated embodiment, if the distributed service includes a sub-service of the TCC mode and a sub-service of the SAGA mode, the sub-service of the TCC mode may be pre-processed first, and then the sub-service of the SAGA mode may be processed after the pre-processing of the sub-service of the TCC mode is successful. If the execution result of the sub-service of the SAGA mode is a successful execution, the sub-service of the TCC mode is executed. Since the sub-service of the TCC mode has been pre-processed, the execution of the sub-service of the TCC mode will definitely be successful, thereby ensuring the consistency of the service processing. If the execution result of the sub-service of the SAGA mode is an execution failure, the sub-service of the TCC mode is rolled back to roll back the sub-service of the TCC mode to the initial state. Therefore, the execution of the sub-service of the TCC mode is also an execution failure, thereby ensuring the consistency of the service processing.

[0109] Based on any of the above embodiments, Figure 3 The illustrated embodiment provides a detailed description of the multi-mode service processing process.

[0110] Figure 3 This is a flowchart of a multi-mode service processing method provided in an embodiment of the present application. Figure 3 , the method may include:

[0111] S301: Obtain a business processing request.

[0112] S302: Preprocess each first sub-service respectively.

[0113] It should be noted that the execution process of S301-S302 can refer to the execution process of S201-S202, and will not be repeated here.

[0114] S303: Determine whether preprocessing of each first sub-service is successful.

[0115] If yes, execute S305.

[0116] If not, execute S304.

[0117] S304: Roll back the pre-processed first sub-service.

[0118] After the pre-processed first sub-business is rolled back, the second sub-business is no longer processed. In this case, both the execution results of the first sub-business and the execution results of the second sub-business are execution failures.

[0119] S305: Perform service processing on at least one second sub-service to obtain a second execution result corresponding to the at least one second sub-service.

[0120] S306: Determine whether a second execution result corresponding to at least one second sub-service is successful.

[0121] If yes, execute S307.

[0122] If not, execute S308.

[0123] If each of the at least one second sub-service is successfully executed, the second execution result is determined to be execution success. If any of the at least one second sub-service fails to be executed, the second execution result is determined to be execution failure.

[0124] It should be noted that the execution process of S306 can refer to the execution process of S203, which will not be described in detail here.

[0125] S307 : Execute each first sub-service respectively to obtain a first execution result corresponding to each first sub-service.

[0126] If each second sub-service is successfully executed, each first sub-service is executed, and since the first sub-service has been pre-processed, the first execution result of the execution of the first sub-service is successful. That is, the execution results of the first sub-service and the second sub-service are both successful, ensuring the consistency of the execution results of the first sub-service and the second sub-service.

[0127] S308: Determine a second sub-service that has been processed in at least one second sub-service.

[0128] The second sub-business that has been processed includes: a second sub-business that has completed the business processing and the execution result is successful execution, and a second sub-business that has completed part of the business processing and the execution result is failed execution.

[0129] S309: Perform reverse business processing on the second sub-business that has been processed.

[0130] The reverse business process refers to canceling the process that has been executed by the second sub-business. The reverse business process is performed on the second sub-business, so that the state of the second sub-business can be rolled back to the initial state, and the initial state is the state before the business process is performed.

[0131] For example, assuming that the business processing of the second sub-business is: depositing a predetermined amount into account 1, then the reverse business processing of the second sub-business is: deducting the predetermined amount from account 1.

[0132] S310 . Perform rollback processing on each first sub-service respectively to obtain a first execution result corresponding to each first sub-service.

[0133] If the processing of the second sub-service fails, each first sub-service is rolled back to make the state of each first sub-service roll back to the initial state. Since only the first sub-service is pre-processed, rolling back the first sub-service means rolling back the pre-processing of the first sub-service, that is, canceling the pre-processing of the first sub-service.

[0134] For example, the pre-processing of the first sub-business includes: freezing the reserved amount in Account 1 , and the rollback processing of the first sub-business refers to unfreezing the reserved amount in Account 1 .

[0135] When the second sub-service fails to be processed, the first sub-service is also rolled back, so that the first execution result service corresponding to the first sub-service fails to execute. That is, the execution result of the first sub-service and the execution result of the second sub-service are both execution failures, ensuring the consistency of the execution results of the first sub-service and the second sub-service.

[0136] exist Figure 3 In the illustrated embodiment, if the distributed service includes a sub-service of the TCC mode and a sub-service of the SAGA mode, the sub-service of the TCC mode may be pre-processed first, and then the sub-service of the SAGA mode may be processed after the pre-processing of the sub-service of the TCC mode is successful. If the execution result of the sub-service of the SAGA mode is a successful execution, the sub-service of the TCC mode is executed. Since the sub-service of the TCC mode has been pre-processed, the execution of the sub-service of the TCC mode will definitely be successful, thereby ensuring the consistency of the service processing. If the execution result of the sub-service of the SAGA mode is an execution failure, the sub-service of the TCC mode is rolled back to roll back the sub-service of the TCC mode to the initial state. Therefore, the execution of the sub-service of the TCC mode is also an execution failure, thereby ensuring the consistency of the service processing.

[0137] Based on any of the above embodiments, Figure 4-Figure 6 , the above multi-mode business processing method is explained through specific examples.

[0138] Figure 4 This is a diagram of the architecture of the distributed service provided in the embodiment of this application. Figure 4, assuming that the distributed service is that the user purchases financial products on a third-party platform through account 1, the distributed service includes 5 sub-services, which are: deducting a predetermined amount from account 1 (sub-service 1), depositing the predetermined amount into a third-party account (sub-service 2), executing the transaction process (sub-service 3), deducting a predetermined amount from a third-party account (sub-service 4), and depositing a predetermined amount into account 2 (sub-service 5). Among them, sub-service 1, sub-service 2, and sub-service 3 are TCC modes, and sub-service 4 and sub-service 5 are SAGA modes.

[0139] Next, combine Figure 5-Figure 6 ,right Figure 4 The processing process of the distributed service shown is explained.

[0140] Figure 5 A schematic diagram of a processing process provided by an embodiment of the present application. Figure 5 When processing distributed services, first pre-process sub-service 1, sub-service 2, and sub-service 3 respectively. Assuming that the pre-processing of sub-service 1, sub-service 2, and sub-service 3 is successful, then the service processing of sub-service 4 and sub-service 5 is performed. If the service processing of sub-service 4 and sub-service 5 is successful, that is, the execution results corresponding to sub-service 4 and sub-service 5 are both successful, then the execution processing of sub-service 1, sub-service 2, and sub-service 3 is performed respectively. Since sub-service 1-sub-service 3 has been pre-processed, the execution result of the execution processing of sub-service 1-sub-service 3 must be successful. That is, the execution results of sub-service 1-sub-service 5 are all successful, which ensures the consistency of service execution.

[0141] Figure 6 A schematic diagram of a processing process provided by an embodiment of the present application. Figure 6 When processing distributed services, sub-service 1, sub-service 2, and sub-service 3 are pre-processed respectively. Assuming that the pre-processing of sub-service 1, sub-service 2, and sub-service 3 is successful, then the business processing of sub-service 4 and sub-service 5 is performed. Assuming that the business processing of sub-service 4 is successful, and the business processing of sub-service 5 fails, then the reverse business processing of sub-service 4 is continued, so that the execution results of sub-service 4 and sub-service 5 are both execution failures. After the execution of sub-service 4 and sub-service 5 fails, the rollback processing is performed on sub-service 1-sub-service 3 respectively, so that the execution results of sub-service 1-sub-service 3 are all execution failures. That is, the execution results of sub-service 1-sub-service 5 are all successful, which ensures the consistency of business execution.
