The life cycle of spring beans

Bean's life cycle:

Definitions are defined in XML files <bean> sub-tags, and objects that define a class need to use beans for automatic management injection

Initialization is the use of getting a bean container context and then initializing using the context call Start method.

Use is to get the instance in the corresponding bean

Destroy is the bean does not need to be used when the bean-related resource information to destroy

Initialization

Case (tested with JUNIT4)

　

 Package org.bean.example;  Public class beanlifecycle {        publicvoid  start () {        System.out.println ("Bean Start" );    }      Public void Stop () {        System.out.println ("Bean Stop");}    }
