在struts.xml 里面配置一下文件 


<package name="default" namespace="/" extends="struts-default">
<action name="LoginAction" method="login" class="com.LoginAction">
<result>/success.jsp</result>
</action>
</package>
2.编写一个Login.jsp
   <form action="LoginAction.action" method="post">
       用户名:<input type="text" name="username">
       密码:<input type="password" name="password">
       <input type="submit" value="提交">
3.编一个success.jsp
4.编写一个LoginAction.java类（这里使用的是ModelDriver实现的）
主要代码
public class LoginAction extends ActionSupport implements ModelDriven<User> {
    
    private User user=new User();


    public String login(){
    System.out.println(user.getUsername());
        
        return SUCCESS;
    }


    public User getModel() {
    
        return user;
    }

}

5.编写一个User.java类

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;
    }

}
