package com.lsz.spring.action;

public class User {
    /**

     */
    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>
