In this embodiment, the setting message middleware acquires the state change information uploaded by each microservice 20, and sends the state change information to other microservices 20 in real time based on the pre-stored first local registry, so that each microservice 20 can update its own second local registry, and further each microservice 20 can acquire the change condition of each other microservice 20 in real time, and update its own second local registry in real time, so that the second local registry of each microservice 20 can be updated in real time, and data transmission between the microservices 20 can be performed normally.
In this embodiment, the message middleware is preferably a Kafka Server, and the Kafka Server has the characteristics of high concurrency and low delay, and can simultaneously change multiple microservices 20. The change efficiency is faster, and the change can be completed within 1s generally, so that the time difference of service state modification is greatly shortened. Thus, real-time updates of the second local registry larger than the respective microservice 20 can be achieved. In addition, the first local registry and the second local registry each contain instance ids (instanceids), application names (applicationnames), and instance states (statuses) of other microservices 20 (which typically do not include themselves). The main role of naming is to avoid local updates being performed by the same service name, since the same services do not need to be aware of each other's existence, but rather are independent instances. Each service instance can judge whether the application name is the same as the service instance, if the application name is the same as the application name, the updating is skipped, otherwise, the local refresh logic refreshRegister is called for updating.
In one embodiment, the data connection module 10 includes a sending sub-module and an information obtaining sub-module, the sending sub-module is connected to the information obtaining sub-module, and the sending sub-module is used for connecting to each micro-service 20; the information obtaining submodule is configured to obtain unique identification information of other micro services 20 from the local registry, and send the unique identification information to the sending submodule, and the sending submodule sends the state change information to other micro services 20 based on the unique identification information of other micro services 20.

Specifically, the unique identification information is the instance ID, and then the corresponding microservice 20 is found according to the instance ID to send the state change information. Therefore, the state information can be sent to the micro-service 20 recorded in the first local registry, and the real-time update of the data is realized.
In one embodiment, the microservice 20 comprises a receiving module and a data processing module, the receiving module is connected with the data processing module, and the receiving module is connected with the data connection module 10; the receiving module is configured to receive the state change information sent by the data connection module 10, and forward the state change information to the data processing module, where the data processing module changes corresponding information in the second local registry based on the state change information.
In this embodiment, the receiving module is configured to receive the state change information sent by the data connection module 10, and forward the state change information to the data processing module, and the data processing module changes corresponding information in the second local registry based on the state change information, so that real-time update of content in the second local registry can be realized, and each microservice 20 has state information of other microservices 20, thereby enabling normal data transmission between the microservices 20 to be realized.
In one embodiment, the data processing module comprises a first processing submodule and a second processing submodule; the first processing submodule and the second processing submodule are respectively connected with a receiving module; the first processing sub-module is configured to replace corresponding state information in the second local registry when the received state change information is update information of the microservice 20; and the second processing sub-module is configured to delete the corresponding state information in the second local registry when the received state change information is update information of the microservice 20.

s1: receiving the state change information uploaded by the first microservice 20;
s2: the state change information is forwarded to other microservices 20 in the table based on a pre-stored local registry.
As described above, the setting message middleware acquires the state change information uploaded by each microservice 20 and sends the state change information to other microservices 20 in real time based on the first local registry stored in advance, so that each microservice 20 can update its own second local registry, and each microservice 20 can acquire the change condition of each other microservice 20 in real time and update its own second local registry in real time, thereby updating the second local registry of each microservice 20 in real time and enabling data transmission between the microservices 20 to be performed normally.
