2.userservice.java

Name the class by using @service

The same is true with the @controller ("UserService") effect.

If you use @controller, then you can only use a hump like userservice.

 PackageCom.sun.service;Importjava.util.ArrayList;ImportJavax.annotation.Resource;Importorg.springframework.beans.factory.annotation.Autowired;ImportOrg.springframework.stereotype.Service; @Service ("UserService") Public classUserService {PrivateString name; PrivateArrayList arr;  PublicArrayList Getarr () {returnarr; }     Public voidSetarr (ArrayList arr) { This. arr =arr; }     PublicUserService () {System.out.println ("This is Chushihua"); }     PublicString GetName () {returnname; }     Public voidsetName (String name) { This. Name =name; }     Public voidinit () {System.out.println ("Init------------"); }     Public voidCleanup () {System.out.println ("Cleanup------------"); }        }    

3.helloworld.java

 PackageCom.sun.service;ImportOrg.springframework.context.ApplicationContext;ImportOrg.springframework.context.support.AbstractApplicationContext;ImportOrg.springframework.context.support.ClassPathXmlApplicationContext; Public classHelloWorld { Public Static voidMain (string[] args) {//TODO auto-generated Method StubAbstractapplicationcontext app =NewClasspathxmlapplicationcontext ("Service.xml"); UserService US= (UserService) app.getbean ("UserService"); Us.setname ("Hello World");        System.out.println (Us.getname ()); //us.setname ("Sunzhiyan");        /*System.out.println (Us.getname ());        for (int i = 0;i < Us.getarr (). Size (); i++) {System.out.println (Us.getarr (). get (i)); } app.registershutdownhook ();*/            }}

This allows for output.
