求教structs传值问题

sdliuchenhui 2017-07-07 04:38:32

用的SSH框架，之后下面的代码一直显示没有办法获取到表单中的username和Password的值，输出的值为空值。
求解决办法

之前网上说的方法都有试过，可是哪种方法都是值传不过去
主界面的代码：



<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Insert title here</title>

</head>

<body>

<form action="LoginAction" method="post">

用户名<input type="text" name="username">

密码<input type="text" name="password">

<input type="submit" value="登录">

</form>

</body>

</html>

Struts中的代码：



<package name="testactionpackage" extends="struts-default" namespace="/">

		<action name="LoginAction" class="com.action.LoginSystemAction">

			<result name="SUCCESS">/success.jsp</result>

			<result name="ERROR">/error.jsp</result>

		</action>

		

	</package>

LoginSystemAction中的代码：



package com.action;



import com.opensymphony.xwork2.ActionSupport;



public class LoginSystemAction extends ActionSupport

{

	private String username;

	private String password;

	@Override

	public String execute()throws Exception

	{

		if("test".equals(username)&&"123456".equals(password))

		{

			return "SUCCESS";

		}else{

			System.out.println(username);

			System.out.println(password);

		    return "ERROR";

		}

	}

	

	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;

	}



}
