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" >
            <property name="userservice" ref="userService"></property>
         </bean>
      */

 }
