Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
The applicant finds that, during the process running, the process node needs to be analyzed, and a service application and a program message need to be created to realize the service operation corresponding to the process node. When the procedure operation is rejected, when the executed node is compensated, the procedure node also needs to be analyzed, and an application program and a message for compensation are created, so that the overhead of program resources and storage resources is large. Based on this, the present disclosure provides a flow rollback compensation method, which can effectively reduce the overhead of program resources and storage resources.
Fig. 1 is a flowchart illustrating a method for compensating for a flow backoff according to an embodiment of the present disclosure, where as shown in fig. 1, the method includes:
in S11, when the procedure operation is rejected, a procedure node to be rolled back is determined.
The process may be a process running in a single local system, or a process running in a distributed system, and the process is run through cooperation of multiple systems. For example, the rejections of the process operation may be that when the process operates to a certain node, the current state of the process cannot meet the approval condition of the task of the node, and the task cannot pass, then the rejections of the process operation occur. For example, the user submits the leave approval, and the leave approval is rejected when the supervisor conducts the approval, and the leave approval is returned to the user node, and the process is rejected at this time. In another example, the process execution rejections may be performed when the process is executed to a certain node and the node task is not successfully executed due to network or system interruption during the execution of the node task. For example, in the payment process of the user, the user submits a payment request and completes payment deduction, and when the payment is performed, because the network is interrupted and the payment fails, the user returns to the user node, and the user needs to be compensated, and the process operation is refuted.
For example, when the flow node to be rolled back is determined when the process operation is rolled back, the flow node to be rolled back may be determined according to the completion time of the flow node, and the flow node with the latest completion time is determined as the flow node to be rolled back.
In S12, if it is determined that the process node to be rolled back needs to be automatically compensated, updating a state of a suspended asynchronous message corresponding to the process node to be rolled back to an operating state, where the asynchronous message includes an application identifier of an application program corresponding to the process node to be rolled back, the application program is acquired when the process node to be rolled back performs a business operation, and the application program includes a compensation subprogram for compensating the process node to be rolled back.
The automatic compensation of the process node is compensation that can be realized only by executing the logic of the compensation subprogram, for example, automatic refund when payment fails in the payment process.
For example, a compensation identifier may be preset for a process node that needs to be automatically compensated in a process, and the identifier information is used to indicate that the process node needs to be automatically compensated, so that whether the process node needs to be automatically compensated may be determined by detecting whether the process node to be rolled back is provided with the compensation identifier.
In S13, the back-off process node is compensated according to the asynchronous message.
For example, the application program includes a compensation subprogram for compensating the flow node to be rolled back, and the compensation subprogram in the application program corresponding to the application identifier included in the asynchronous message may be directly executed based on the service data of the flow, so as to compensate the flow node. The method for acquiring the service data of the process may be the prior art, and is not described herein again.
In the technical scheme, when the process operation is rejected, a process node to be rolled back is determined; and when determining that the flow node to be backed off needs to be automatically compensated, updating the state of the suspended asynchronous message corresponding to the flow node to be backed off into an operating state, so as to compensate the flow node to be backed off according to the asynchronous message. According to the technical scheme, the application program is acquired when the process node performs business operation and comprises the compensation subprogram for compensating the back process node, so that when the process node is compensated, the compensation can be performed based on the application program and the asynchronous message of the process node during the business operation, the repeated analysis of the process node is avoided, and the efficiency of the process back compensation is improved. In addition, the application program and asynchronous messages do not need to be created again, the expenses of program resources and storage resources can be effectively reduced, the reading and writing frequency of the database is reduced, and the simplicity and the easiness of the process rollback compensation are improved.
Optionally, the method further comprises:
and analyzing the flow node to be executed during flow operation to obtain the application identifier corresponding to the flow node to be executed.
And acquiring the application program corresponding to the flow node to be executed according to the application identifier.
In an exemplary embodiment, during process setting, an application program of an automatic compensation type is set for a process node that needs automatic compensation, where the application program includes both the service subprogram for executing normal service of the process node and the compensation subprogram for compensating the process node, and associates an application identifier of the application program with the process node. In the prior art, a plurality of global extension attributes are generally required to be created to execute the compensation application program. This can result in multiple extended attributes for nodes in the process that need automatic compensation. In the above technical solution, by associating the application program with the process node, it is not necessary to create a plurality of extended attributes, and the storage resource occupation corresponding to the extended attributes can also be effectively reduced, thereby further reducing the overhead of the storage resource.
In this embodiment, during the process running, the process node may be analyzed, so that the application identifier corresponding to the process node may be obtained, and the application program corresponding to the application identifier may be obtained according to the application identifier.
If the type of the application program corresponding to the flow node to be executed is an automatic compensation type and the operation mode of the application program corresponding to the flow node to be executed is asynchronous processing, establishing an asynchronous message corresponding to the flow node to be executed;
and if the flow node to be executed is successfully executed, setting the state of the asynchronous message corresponding to the flow node to be executed as a suspended state.
The type and the operation mode of the application program can be preset. For example, an application program corresponding to a flow node may be set by a flow designer, and when the corresponding application program is set, the type and the operation mode of the application program are set.
In this embodiment, if the type of the application program corresponding to the flow node is an automatic compensation type, it indicates that the flow node needs to perform automatic compensation when the flow operation is refuted. Therefore, after the flow node to be executed is successfully executed, the state of the asynchronous message corresponding to the flow node to be executed may be set to the suspended state. Setting and updating of the state of an asynchronous message may be accomplished, for example, by associating a state identification for the message. For example, when the asynchronous message is generated, the state identifier may default to a null value or a running state, and after the flow node to be executed is successfully executed, the state identifier of the asynchronous message is set to a suspended state. For another example, the state flag may also be represented by a binary number, such as 1 for the run state and 0 for the suspend state. By the technical scheme, when the flow node is compensated, the asynchronous message does not need to be generated again, so that the reading and writing frequency of the database can be effectively reduced, and the resource overhead of creating the message is reduced.
Optionally, if the operation mode of the application program corresponding to the flow node to be executed is synchronous processing, the service operation of the flow node to be executed may be directly executed. If the type of the application program corresponding to the flow node to be executed is not the automatic compensation type and the operation mode of the application program is asynchronous processing, an asynchronous message corresponding to the flow node to be executed is created, and the asynchronous message can be directly deleted after the flow node to be executed is successfully executed.
Optionally, the asynchronous message corresponding to the flow node to be backed off further includes a node identifier of the flow node to be backed off;
compensating the flow node to be backed according to the asynchronous message, comprising:
and sending the asynchronous message to an application program processor, and executing the compensation subprogram by the application program processor according to the process node information corresponding to the node identifier in the asynchronous message.
Wherein, the application processor can carry out unified scheduling processing on the asynchronous messages. When the application processor schedules the asynchronous message, the corresponding application program can be obtained based on the application identifier in the asynchronous message, so as to determine a compensation subprogram in the application program; and acquiring the process node information of the process node corresponding to the node identification from the process instance based on the node identification in the asynchronous message. Therefore, the application processor can execute the compensation subroutine according to the flow node information, thereby compensating the flow node. For example, the corresponding process node is acquired as a deduction node according to the node identifier, the process node information is a user account balance, and the service data, such as the deduction amount, can be acquired by executing the compensation subprogram, so that the deduction amount is compensated to the user balance to complete compensation of the deduction node.
Therefore, in the above technical solution, the asynchronous message is sent to the application processor, so that the application processor schedules the asynchronous message, on one hand, uniform processing of the asynchronous message is facilitated, and on the other hand, the compensation service can be processed separately, so as to improve efficiency and throughput of process processing and reduce pressure of a process engine.
Optionally, the method further comprises:
and after the flow node to be backed off is compensated, deleting the asynchronous message corresponding to the flow node to be backed off.
After the flow node to be backed off is compensated, the asynchronous message is not needed to be used in the subsequent processing process of the flow, and the asynchronous message corresponding to the flow node to be backed off can be deleted at the moment, so that the occupation of storage resources can be further reduced, and the storage space is saved.
Optionally, the method further comprises:
after the flow node to be backed off is compensated according to the asynchronous message, determining the next flow node to be backed off according to the flow operation information; the previous process node of the process node to be reversed in the process of process operation can be used as the next process node to be reversed according to the process operation information, so that the completed process node is traversed reversely to perform process reversion compensation.
Determining the next flow node to be backed off as a new flow node to be backed off, and if the flow node to be backed off is determined to need to be automatically compensated, updating the state of the suspended asynchronous message corresponding to the flow node to be backed off into an operating state; and compensating the flow node to be rolled back according to the asynchronous message.
The specific implementation of the above compensation has been described in detail above, and is not described herein again.
By the technical scheme, the completed process nodes in the process can be reversely traversed according to the process running information, and each process node needing automatic compensation in the process is compensated in the reverse traversing process, so that the data consistency in the process running is ensured.
