The storage server 103 is mainly used to store the domain events generated by the application server 102 during execution or running. The domain events can be permanently stored or stored. Specify the duration. In addition, the storage server 103 may be a separate server for storage, or may be a part of the memory 1021 of the application server 102 , that is, the domain events generated by the application server 102 during execution or running are stored in the memory 1021 .

FIG. 2 is a data processing method provided by an embodiment of the present invention, applied to an application server, where the application server at least includes a first event bus and a second event bus, wherein the first event bus is used to transmit data for the first operation of the service. Domain event, the second event bus is used to transmit the domain event of the second operation of the service, referring to FIG. 2 , the method includes the following steps.

Step 201: Receive a data processing request, where the data processing request includes a user ID, an electronic voucher ID, and an operation type, and the electronic voucher is used to indicate that a preset state is satisfied between the user and the service.

Wherein, the electronic certificate identifier is used to uniquely identify the electronic certificate, and the electronic certificate is used to indicate that the user and the service meet a preset state. For example, when the electronic certificate is an order generated by the user ordering a service, the electronic certificate identifier can be is the order identifier of the order, and the order identifier can be an order number, and the order number is used to indicate that the user has ordered the service.

In addition, the operation type includes a first operation and a second operation, when the data processing request includes a user ID and an electronic credential ID, the operation type is the first operation, and when the data processing request includes a user ID and a service ID, the The operation type is the second operation. For example, when the user needs to handle or cancel a certain business, the first operation type may refer to canceling the business to be handled, and the second operation may be to handle the required business.

Step 202: If the operation type is the first operation, based on the electronic certificate identifier and the first correspondence, mark the first domain event as a rollback event, the first domain event is the domain event corresponding to the electronic certificate identifier, and the first domain event is the domain event corresponding to the electronic certificate identifier. A corresponding relationship includes an electronic certificate identifier and a domain event corresponding to the electronic certificate identifier.

The first correspondence refers to the correspondence between the electronic certificate identifier and the domain event. The domain event corresponding to the electronic certificate identifier can be determined through the electronic certificate identifier, and the first correspondence can be stored separately or stored in in the event database.

For example, if the user wishes to cancel the SMS call service previously handled, and the electronic voucher ID is the order ID when handling the SMS call service, the application server obtains and handles the SMS call from the first correspondence based on the order ID when handling the SMS call service. The first domain event corresponding to the order identifier during the service, that is, ordering the short message calling service, thereby marking the first domain event ordering the short message calling service as a fallback event.

It should be noted that the first correspondence, that is, the electronic certificate identifier and the domain event corresponding to the electronic certificate identifier, is stored when the electronic certificate is generated before and the domain event is generated based on the electronic certificate identifier. For a method for generating a domain event based on an electronic credential identifier, reference may be made to a data processing method whose operation type is the second operation, which will not be repeated in this embodiment of the present invention.

Step 203: query the event database based on the user ID, and obtain other domain events except the first domain event among the domain events corresponding to the user ID; wherein, the event database includes the user ID, the domain events corresponding to the user ID, and the domain events The time at which the event occurred.

Wherein, the event database may contain, in addition to the user ID, the domain event corresponding to the user ID, and the occurrence time corresponding to the domain event, the electronic credential ID, the event data, or the event status, and their respective associations with the user ID and the event status. The corresponding relationship between the domain events, etc., in addition, the occurrence time corresponding to the domain event may be accurate to seconds, milliseconds, or microseconds, which is not limited in this embodiment of the present invention.

In addition, the event database can be stored in the application server, or can be stored separately in the storage server, and the data information in the event database can be permanently stored or stored for a preset period of time. When the data information is When permanently stored, the first operation can be performed on any domain event in the event database based on the user ID and the electronic voucher ID. When the data information is stored within a preset time period, the user ID and the electronic voucher information The first operation is performed on any domain event within the preset duration, which is not limited in this embodiment of the present invention.

For example, if the user ID is 1234567, the electronic voucher ID is the order ID and ID1, and the first domain event is event 1, the application server queries the event database shown in the following table 1 based on the user ID 1234567, and obtains the domain event corresponding to the user ID 1234567 , the other domain events except event 1 are event 2 and event 3.

Table 1

It should be noted that the embodiment of the present invention only takes the event database shown in Table 1 above as an example for description. The corresponding relationship does not limit the embodiments of the present invention.

Optionally, when the data information in the event database is stored within a preset duration, the application server obtains, from the event database, the domain events corresponding to the user ID within the preset duration before the current moment; It is assumed that the domain events corresponding to the user ID in the duration include the first domain event, then delete the first domain event and obtain other domain events except the first domain event; if the preset duration before the current moment corresponds to the user ID If the domain event does not contain the first domain event, an error message is sent, and the error message is used to indicate that an error occurs in the first operation.

That is, only domain events within the preset duration before the current moment are stored in the event database, and domain events exceeding the preset duration before the current moment are deleted, if the first domain event belongs to the preset duration before the current moment. The domain events within the duration will be stored in the event database, so that after deleting the first domain event in the domain events corresponding to the user ID, other domain events except the first domain event can be obtained; if the first domain event The event is a domain event that does not belong to the preset time period before the current moment, so it will not be stored in the event database, so that the application server can send an error message to the user terminal, and the error message is used to indicate that an error occurred in the first operation, that is, Yes, the application server sends the information that the first domain event cannot be rolled back to the user terminal.

It should be noted that the preset duration may be set in advance, and the preset durations corresponding to different domain events may be the same or different, which is not limited in this embodiment of the present invention.

For example, in the communication operation process, it is stipulated that the subscription of the SMS call service cannot be unsubscribed for more than three months. If the first field event is the subscription of the SMS call service, the preset duration is three months, and the event database within three months It includes the event subscription SMS call service in the first field, and the user can apply for a rollback. If the event database exceeds three months, the event subscription SMS call service in the first field will be deleted. If the user applies for a rollback, the application server will send a message that cannot Fallback information.

Step 204: Reprocess other domain events in sequence according to the time sequence of occurrence of the domain events to obtain processed service status information corresponding to the user ID.

Since each domain event has an event listener, the corresponding domain event is processed by the event listener. Therefore, when other domain events are reprocessed in the order of the occurrence time of the domain events, other domain events can be reprocessed. The domain events are sent to the first event bus in the order of the occurrence time of the domain events, and the corresponding event listeners obtain other domain events from the first event bus in turn, and process them in a synchronous listening mode. The processed service status information corresponding to the user ID.

Among them, processing in the mode of synchronous listening means that the sending and receiving of domain events are processed in the same thread, and no thread switching is performed to ensure that each domain event is processed before processing the next domain event.

It should be noted that when the application server initializes the system, there are corresponding event listeners for different domain events. The purpose of the event listener is to call different domain services for different domain events, and capture the pending events when the system is running. The processed domain event calls the corresponding domain service of the corresponding domain event, so as to process the corresponding domain event. For the specific domain event processing, reference may be made to the related art, which is not described in this embodiment of the present invention.

Step 205: Update the service state information corresponding to the user ID in the state database according to the processed service state information corresponding to the user ID, wherein the state database includes the user ID and the service state information corresponding to the user ID.

Since the status database contains the user ID and the business status information corresponding to the user ID, the business status information corresponding to the user ID has changed after the first operation, and in order to restore the business status information corresponding to the user ID in the status database to the first In the state when an event in a domain does not occur, the business state information corresponding to the user ID in the state database can be updated according to the processed business state information corresponding to the user ID, that is, the business state information corresponding to the user ID in the state database can be updated. Replace with the processed service status information corresponding to the user ID.

It should be noted that the status database is used to store the business status information of the user, and the status database includes the user ID and the business status information corresponding to the user ID, and the business status information may include the business ID, the electronic voucher ID, the information The creation time, etc., is not specifically limited in this embodiment of the present invention.

Optionally, referring to FIG. 3, after step 203, the method further includes:

Step 206: If there is a preset association relationship between the second domain event and the first domain event among other domain events, send error information, where the error information is used to indicate that an error occurs in the first operation.

The preset association relationship means that the first domain event and the second domain event are related to each other, and when the second domain event exists, the first domain event must also exist. For example, in the communication operation process, it is stipulated that package B includes the SMS calling service. If the second domain event is the subscription package B, and the first domain event is the SMS calling service subscription, since the subscription package B and the SMS calling service are related to each other, when When the event subscription package B in the second domain exists, the event subscription SMS call service in the first domain must also exist.

Specifically, in other domain events, if there is a preset association relationship between the second domain event and the first domain event, it is determined that the first domain event cannot be rolled back. Therefore, the application server may send an error message to the user terminal, the The error information is used to indicate that an error occurs in the first operation, that is, the application server sends the information that the first domain event cannot be rolled back to the user terminal.

In the data processing method provided by the embodiment of the present invention, by receiving a data processing request, the data processing request includes a user ID, an electronic voucher ID, and an operation type. If the operation type is the first operation, the data processing request is based on the electronic voucher ID and the first corresponding relationship. , mark the first domain event as a fallback event, and then query the event database based on the user ID to obtain other domain events except the first domain event among the domain events corresponding to the user ID, and classify other domain events as domain events Reprocessing is performed in the order of the occurrence time of the user ID, and the processed service status information corresponding to the user ID is obtained, and the service status information corresponding to the user ID in the status database is updated according to the processed service status information corresponding to the user ID. , so that based on the existing business logic, the domain events other than the fallback events are replayed positively, and there is no need to develop additional change log tables for status information, which reduces the burden on developers and ensures business Fallback conditions.

FIG. 4 is a data processing method provided by an embodiment of the present invention, which is applied to an application server. The application server includes at least a first event bus and a second event bus, wherein the first event bus is used to transmit data for the first operation of the service. Domain event, the second event bus is used to transmit the domain event of the second operation of the business, and the method includes the following steps:

Step 301: Receive a data processing request, where the data processing request includes a user ID, a service ID, and an operation type.

The operation type includes a first operation and a second operation. When the data processing request includes a user ID and an electronic credential ID, the operation type is the first operation. When the data processing request includes a user ID and a service ID, the operation type is the first operation. The operation type is the second operation. For example, when the user needs to handle or cancel a certain business, the first operation type may refer to canceling the business to be handled, and the second operation may be to handle the required business.

Step 302: If the operation type is the second operation, generate an electronic voucher based on the data processing request, and the electronic voucher is used to indicate that a preset state is satisfied between the user and the service.

Wherein, generating the electronic voucher based on the data processing request refers to generating the electronic voucher based on the user ID and the service ID included in the data processing request. For example, in the process of communication operation, the data processing request may be a request for a user to order a service, and the application server may generate an order based on the user ID and the service ID that the user expects to order. The electronic voucher is the generated order, the electronic voucher identifier can be the order identifier of the order, and the order identifier can be the order number.

Step 303: Based on the identifier of the electronic certificate, generate a first domain event corresponding to the identifier of the electronic certificate.

The identifier of the electronic certificate is the electronic certificate identifier. After generating the first domain event corresponding to the electronic certificate identifier based on the electronic certificate identifier, the application server may also generate the electronic certificate identifier and the first domain event corresponding to the electronic certificate identifier. is stored in the first corresponding relationship, and the first corresponding relationship can be stored separately or in the event data.
