 1 package com.lsz.spring.action;

 3 public class User {

 6      */
 7     private String username;
 8     public void setUsername(String username) {
 9         this.username=username;
10     }
11     public String getUsername() {
12         return username;
13     }    
14     /*
15     <bean  >  
16     <span style="white-space:pre">  </span><property name="username" value="admin"></property>  
17     </bean>

19     /**

21      */
22     
23          private UserService ;  
24          public UserServicegetUserservice() {

26          }  
27          public void setUserservice(UserService userservice){  
28              this.userservice= userservice;  
29          }
