struts2实现登陆主要是为了学习获取请求参数,以及向页面回传数据
jsp代码
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path = request.getContextPath() + "/";
%>
<!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=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form action="<%=path %>user/login.action" method="post">
账号:<input type="text" name="account"><br>
密码:<input type="password" name="pwd"><br>
<input type="submit" value="登陆"><br>
</form>
</body>
</html>
action类代码
package com.xingxue.action;
public class UserAction {
public String account;
public String pwd;
public String msg;
public String userLogin() {
if("admin".equals(account) && "123123".equals(pwd)) {
msg = "loign ok!";
return "OK";
}else {
msg = "loign no!";
return "NO";
}
}
}
主要:此处只要保证属性为public,名字和页面上传的参数名相同,strus2会自动将请求参数注入到我们的action的属性中,及获取到了请求参数
跳转页面代码
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path = request.getContextPath() + "/";
%>
<!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=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
nononoon
${msg }<br>
${account }<br>
${pwd }<br>
</body>
</html>
只要是action的属性 在跳转页面都可以进行获取,此处struts2在跳转页面的时候会自动将参数传入request对象中,然后在跳转页面
