"Introduction" Have you ever encountered two (multiple) systems that need to synchronize certain data through a timed task? Are you struggling with the problem of calling and communicating between different processes of heterogeneous systems? If so, congratulations, the messaging service makes it easy for you to solve these problems. The Messaging service specializes in solving data exchange (message notification/communication) issues between multiple systems and heterogeneous systems, and you c

First, IntroductionRABBITMQ is a popular open source Message Queuing system, developed in Erlang language. The distributed communication security policy for Erlang can be attributed to all or None.
We have been using RABBITMQ to integrate and interface various business systems (such as SAP, OA, EHR, KMS, visitor systems, AD, etc.) for a long time, initially establishing an enterprise service bus (ESB). As the new business system continues to be connected to the ESB, some problems have been found in practice and some experience has been summarized below, which focuses on how to break the RABBITMQ socke
In the MQ messaging framework, spring officially provides RABBITMQ use cases, using the springboot approach (MESSAGING-RABBITMQ); Next, we use the XML configuration to combine RABBITMQ into SPRINGMVC to play.
