数据获取

Question

小弟最近学习struts  ，做了一个用户登录的小练习，但是输入用户名和密码后，获取不到输入的数据。首先在struts.xml中配置：

   
        <action name="index">
            <result >
                /Loginform.jsp
            </result>
        </action>
        
      <action name="LoginAction" class="org.action.LoginAction" method="excute">
      
            <result name="success" >
                /success.jsp
            </result>
</action>

 主界面jsp页面：

<p><h1>用户登录</h1></p>
  <form name="Login" action="LoginAction" method="post">
   用户名：<input type="text" name="username"/><br>
   密码:<input type="password" name="password"/><br>
   <tr colspan="2">
   <td><input type="submit" value="登录"/></td>
   <td><input type="reset" value="取消"/></td>
   </tr>
  </form>

创建一个USER类 ，包含了username和password ：

public class USER {
 private String username;
 private String password;
 
public String getUsername() {
    return username;
}
public void setUsername(String username) {
    this.username = username;
}
public String getPassword() {
    return password;
}
public void setPassword(String password) {
    this.password = password;
}
public USER(){
    //setUsername(getUsername());
    //setPassword(getPassword());
}
public String toString()
{
    return getUsername()+getPassword();
}

}

 action java文件：

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport{

    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    private USER User;

    public USER getUser() {
        return User;
    }
    public void setUser(USER user) {
        User = user;
    }
    
    public String excute() throws Exception{
    
        User=new USER();
        
        //User.username="www";
        //User.password="dede";
        return "success";
    }
}

 最后跳到显示信息的jsp页面success.jsp：只是显示我输入的数据

<s:property value="User" />

 

Answer 1

页面form改为

用户名：


密码:

public String excute() throws Exception{

    System.out.println(User.getUsername());

    //User.username="www";  
    //User.password="dede";  
    return "success";  
}
