Brief introductionIn micro-service, service registration and discovery play a key role in the management of each sub-service subsystem. As the system expands more and more, and the number of systems split into microservices increases correspondingly, the URL to manage and access these microservices becomes tricky, and if we add a micro-service every new one, manually add its URL address or other communicati

"receive /app/change-notice the value sent, and then forward the value to the /topic/notice client." /topic/noticeis an address that is specified when the client initiates a connection, subscribes to the server's message, and is used to receive the return of the server, which we will see when we write the client code. So far, the service-side code coding finished! Next article we will write the client function.Wen/devid (author of Jane's book)Original link: http://www.jianshu.com

It's easy to understand the Spring Bean's life cycle. When a bean is instantiated, it may need to perform some initialization to convert it to a usable state. Similarly, some cleanup work may be required when the bean is no longer needed and removed from the container.
