搭建struts2项目的一些简单易于理解的操作

操作方法

01

从网上下载struts2需要的jar包，以下是需要用到的jar包
02

1.在myeclipse中新建web工程，随便起名字，例如我的是叫logintest
03

2.导入需要引用的jar包，在logintest项目上右键->build path->configure bulid path,点击libraries,点击add external jars...,选择你的struts2需要用到的jar包的位置添加进来，点击ok
04

3.在WebRoot下找到web.xml文件进行配置，将下面的代码粘贴过去 <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" 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_2_5.xsd">  <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class> </filter>  <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
05

在src里面新建一个xml文件命名为struts.xml,然后将下面的代码粘贴到此文件中 <?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" namespace="/demo"> <action name="login" class="com.action.LoginAction" > <result>/loginsuccess.jsp</result> </action> </package> </struts>
06

在src中新建一个包，命名为com.action,在此包下新建一个类命名为LoginAction，将下面的代码站提过去 package com.action; import com.opensymphony.xwork2.ActionSupport; public class LoginAction extends ActionSupport{ 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; } public String execute(){ System.out.println("走进action"); return SUCCESS; } public String login(){ return SUCCESS; } }
07

在WebRoot下新建一个jsp，命名为login.jsp，将下面的代码复制过去 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'login.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">  </head> <body> <form action="/attendance_book/demo/login.action" method="post"> 账号：<input type="text" name="username"/><br/> 密码:<input type="text" name="password"/><br/> <input type="submit" value="确定"> </form> </body> </html>
