The other components of Spring use the classes in this package, which is the basic core of the others, and of course you can use them in your own application system.Externally dependen

You can use the Bean's Init-method and Destroy-method properties to initialize and destroy the bean.Define a Hero class: Packagecom.moonlit.myspring; Public classHero { Public voidborn () {System.out.println ("The hero is born."); } Public voidDefaultborn () {System.out.println ("The hero is born by default."); } Public voiddoAction () {System.out.println ("The Hero Save the world."); } Public voiddead () {System.out.println ("The hero is dead."); } Public voidDefaultdead () {Sys

I. Introduction of Beanfactory1.1. Bean: In spring technology is component-based The most basic is the most commonly used unit In fact, the instance is stored in the spring container. Beans are typically defined in a configuration file, Bean instantiation is managed by the spring IOC container, instances of beans can be accessed through beanfactory, and in fact most of the Java EE appl

There are three ways to define operations before the spring container initializes the bean and destroys it:First: Operations performed prior to initializing and destroying beans through @postconstruct and @PreDestroy methodsThe second is: by defining the Init-method and Destory-method methods in XMLThe third is the implementation of the Initializingbean and Disposablebean interfaces via beansThe following shows the @PostConstruct and @PreDestory1: Def

Spring Configures beans with annotationsConfiguring beans based on annotationsTo configure the Bean's properties based on annotationsScanning components in the ClasspathComponent scanning (component scanning): Spring is able to automatically scan, detect and instantiate components with specific annotations from the classpath.Specific components include the following:[Email protected]: basic annotations that
