spring的依赖注入的最常见的两种方法

 package com.lsz.spring.action;

 public class User {

     /**

      * set注入

      */

     private String username;

     public void setUsername(String username) {

         this.username=username;

     }

     public String getUsername() {

         return username;

     }

     /*

     <bean id="userAction"class="com.lsz.spring.action.User" >

     <span style="white-space:pre">  </span><property name="username" value="admin"></property>

     </bean>

     */

     /**

      * 给对象赋值

      */

          private UserService ;

          public UserServicegetUserservice() {

               return userservice;

          }

          public void setUserservice(UserService userservice){

              this.userservice= userservice;

          }  

     /*

      * <!--对象的声明-->

         <bean id="userService" class="com.lsz.spring.service.UserService"></bean>  

         <bean id="userAction"class="com.lsz.spring.action.User" >
