Spring Cloud Bus

Spring Cloud Config server is responsible for the release git svn stored in the configuration file into REST interface, clients can obtain configuration from the server REST interface. But the client does not take the initiative to perceive changes in the configuration, so take the initiative to acquire new configuration, which requires each client to trigger the respective / refresh via the POST method.

Nodes of a distributed system connected by a Spring Cloud Bus lightweight message broker. This can be used to change the status of a broadcast (e.g., configuration changes), or other management instruction. Spring Cloud Bus provides access via POST method endpoint / bus / refresh, this interface is usually called by git hook function to inform each Spring Cloud Config the client to update the server configuration.

SpringCloudConfig combined SpringCloudBus implement a distributed configuration workflow

Here Insert Picture Description

  1. Submit code to trigger a post request to bus / refresh
  2. server receives the request and sent Spring Cloud Bus
  3. Spring Cloud bus and receive messages to notify other clients
  4. Other client receives a notification request Server clients to obtain the latest configuration
  5. All clients are to get the latest configuration

Message Agent

Message Broker (Message Broker) is a message authentication, transmission, routing architecture pattern. It is a message broker middleware product, its core is a message routing program for receiving and distributing messages, and forwarding to the correct application according to predetermined message processing flow. It includes a separate communication and messaging protocol enables the network communication between the internal tissues and tissue. The purpose is to be able to design proxy incoming messages from the application, and perform some special operations.
