struts2.0学习笔记二(struts2.0第一个程序)
前提配置完后台struts2.0的运行环境
1.helloworld.jsp
<%@ page language="java" import="java.util.*" pageEncoding="gbk"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!--该taglib标签默认包含在了struts2.0的包中了-->
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<s:form action="login">
<s:textfield name="user" label="username"></s:textfield>
<s:textfield name="pwd" label="password"></s:textfield>
<s:submit label="submit"></s:submit>
</s:form>
</body>
</html>
2.配置struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="struts2" extends="struts-default">
<action name="login" class="com.test.action.LoginAction">
<result name="success">/result.jsp</result>
<result name="input">/index.jsp</result>
</action>
</package>
<!--该LOGIN和你页面提交的login要相对应-->
</struts>
3.编写com.test.action.LoginAction
package com.test.action;
import com.bean.Point;
import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport {
String username;
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;
}
@Override
public String execute() throws Exception {
return "success";
}
}
4.显示的result.jsp
<%@ page language="java" import="java.util.*" pageEncoding="gbk"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
username:<s:property value="username"/>
password:<s:property value="password"/>
<!--该username和password和你action中的属性名一定要对应,他相当于是调用了action中相对应属性的get方法-->
</body>
</html>
