 3 public class User {
 4     /**
 5      * set注入
 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 id="userAction"class="com.lsz.spring.action.User" >
16     <span style="white-space:pre">  </span><property name="username" value="admin"></property>
17     </bean>

23          private UserService ;
24          public UserServicegetUserservice() {
