As shown in fig. 1, an embodiment of the present application provides a real-time reliable data synchronous transmission method, where the method includes:
adopting an AOP technology to integrate a persistence frame at a source end, monitoring the integrated persistence frame, and capturing the operation of a business entity in the integrated persistence frame on a business object;

persisting the data change set at the source end, and sending the data change set to the target end;
the target end receives the data change set and persists the data change set at the target end;
and changing the data of the target end according to the data change set so as to synchronize the data of the source end and the data of the target end.
In this embodiment, the attributes of the operation may be, for example: add, update, delete.
In this embodiment, the information of the business object may include, for example, one of the following items: the identification of the business object, the metadata structure of the business object and the original data of the business object.
In this embodiment, the real-time reliable data synchronous transmission method further includes:
presetting a service object set which needs to carry out data synchronous transmission;
judging whether the business object is in the business object set or not according to the identification of the business object,
if so, a data change set is constructed.
In this embodiment, constructing a data change set according to the attribute of the operation and the information of the business object includes:
if the attribute of the operation is addition, acquiring original data and newly added data of the service object, and constructing a data change set according to the original data and the newly added data;
if the attribute of the operation is updating, acquiring original data and updated data of the service object, and constructing a data change set according to the original data and the updated data;
and if the operation attribute is deletion, acquiring the original data of the service object, and constructing a data change set according to the original data.
In this embodiment, the real-time reliable data synchronous transmission method further includes:
the data changeset is serialized into a json string.
In this embodiment, persisting the data change set at the source end includes:
acquiring the context of the service at a source end;
persisting a data change set using a context of a service.

and acquiring the release state of the source end sending the data change set, and feeding back the release state.

and acquiring the processing state of the target end processing data change set, and feeding back the processing state.
In order to facilitate understanding of the real-time reliable data synchronous transmission method exemplified in the embodiment of the present invention, the real-time reliable data synchronous transmission method is further described below:
firstly, an AOP technology integrated persistence frame is adopted at a source end, the integrated persistence frame is monitored, and operations of a business entity in the captured integrated persistence frame on a business object are intercepted, wherein the operations can be insert, update and delete operations.
The attribute of the operation, the value list propertyanmes and the information of the service object can be obtained according to the service entity. The information of the business object may be, for example, an identifier of the business object, a metadata structure of the business object, raw data of the business object, and the like.
And then, determining whether data synchronization processing is needed or not according to the identification of the service object. For example, a service object set which needs to perform data synchronous transmission can be preset at a monitoring end; and judging whether the business object is in the business object set or not according to the identification of the business object, and if so, constructing a data change set.
And after determining that data synchronization is needed, acquiring original data of the business object, and organizing a data change set, such as a changeData change set, according to the updated data and the original data after operation.
And serializing the data change set into json character strings so as to process various different business entities. And acquiring the context of the service in the AOP frame, and storing the serialized json, namely the persistent data change set, by adopting the context of the service. And sending the serialized data change set to an MQ queue, and calling the MQ to send the data change set to a target terminal.
The data change set is persisted at the source end, and manual retry can be carried out according to a retry strategy or after MQ solution when MQ service is temporarily unavailable.
After the target end receives the MQ message, the json data of the data change set is persisted at the target end. The changeset of data is then deserialized, such as the data in the changeset may be in the form of a changeData universal entity. Finally, the reflection call executes consumption processing logic for changeData to synchronize data of the source and the target.
On one hand, the receiving of the MQ queue is not blocked, on the other hand, even if the consumption processing logic is abnormal, the data needing to be processed by the target end cannot be lost, and after the consumption logic is solved, the consumption processing is triggered again.
The source end successfully sends the MQ and directly feeds back the successful issuing to the monitoring end; if the MQ fails to send, the system will retry according to the strategy, such as retry every 5 seconds by default, and if the retry fails for three times, the system feeds back the MQ failure to the monitoring terminal.
When the target end consumes and processes, the target end directly feeds back a processing result to the monitoring end due to asynchronous processing, namely success or failure.
