For the interaction scene between java and a third-party system, the Socket mode is most commonly used at present, which is a typical C/S interaction mode. The server provides services, and service access is carried out through the IP address and the port. The transmission protocol may be a TCP/UDP protocol, and the server and the client agree on a request message format and a response message format.

Corresponding message handling mechanisms are added to systems B and C, for example: and (3) adding a timer, polling and processing the message stored in the step (2), wherein the content of the message can call a corresponding query interface in the agent program for obtaining, and after the processing is finished, a corresponding update interface can be called, and the message is set to be processed, so that the message can be skipped to process other messages in the next processing.
4. When the system B and the system C change and need to be synchronized to the system A, the related content can be packaged into a json string according to the convention with the system A, a corresponding interface in an agent program is called, the json string is transmitted, the interface places the content into a message queue and transmits the message to a message center, and the system A subscribes the related message and consumes the message.
