struts2.0

struts2.0起步

想看第一个简单的struts2.0项目

1、新建项目，引入struts相关的jar包

2、配置web.xml和struts.xml文件

web.xml 
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  
  <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

  <welcome-file-list>
    <welcome-file>login.jsp</welcome-file>
  </welcome-file-list>
</web-app>
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="default"  extends="struts-default">
        <action name="login" class="com.itime.action.LoginAction" method="Test">
            <result name="success">/welcome.jsp</result>
            <result name="login">/login.jsp</result>
        </action>
    </package>

</struts>

3、登录界面login.jsp 和处理action及登录成功页面

login.jsp 
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
   
    <title>Login</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">

  </head>
 
  <body>
   
   <s:form action="login" method="post">
    <s:label value="系统登陆"></s:label>
    <s:textfield name="username" label="账号" />
    <s:password name="password" label="密码" />
    <s:submit value="登录" />
   </s:form>
 
  </body>
</html>
LoginAction 
package com.itime.action;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {
    private static final long serialVersionUID = 1661426853473626469L;

    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;
    }

    @Override
    public String execute() throws Exception {

        if ("邹腾".equals(username) && "admin".equals(password))// 如果登录的用户名=haha并且密码=hehe，就返回SUCCESS；否则，返回LOGIN
        {
            return SUCCESS;
        } else {
            return LOGIN;
        }
    }

    public String Test() throws Exception {
        if ("邹腾".equals(username) && "admin".equals(password))// 如果登录的用户名=haha并且密码=hehe，就返回SUCCESS；否则，返回LOGIN
        {
            return SUCCESS;
        } else {
            return LOGIN;
        }
    }
}
welcome.jsp 
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>welcome</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">
