搭建一個最簡單的struts2的環境：css

1、MyEclipse右鍵new一個Web Project。html

2、將struts2的jar複製黏貼到lib文件夾中。java

3、Web.xml文件，從demo中複製黏貼<filter>和<filter-mapping>內容，其中<url-pattern>，默認寫「/*」，約定俗成、web

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>Struts2_0100</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  <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>
</web-app>

4、從demo中複製struts.xml文件到src文件夾中，apache

　　<struts>標籤中全部內容都註釋掉，留下以備參考，tomcat

　　複製<package>的內容，去掉 <default-action-ref name="index" />
　　將<action> 標籤內容修改以下，app

　　<action name="hello">
            <result>
                /hello.jsp
            </result>
        </action>jsp

　　將index.jsp更名hello.jspide

　　修改hello.jsp的body內容ui

<%@ 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>hello!</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>
    hello !!! <br>
  </body>
</html>

5、把項目部署到tomcat中

6、訪問http://localhost:8080/Struts2_0100/hello.action，其中Struts2_0100爲項目名稱，hello.action必定要寫，能夠簡寫爲hello
