struts2环境搭建

搭建一个最简单的struts2的环境:

一、MyEclipse右键new一个Web Project。

二、将struts2的jar复制黏贴到lib文件夹中。

 

三、Web.xml文件,从demo中复制黏贴<filter>和<filter-mapping>内容,其中<url-pattern>,默认写 “/*”,约定俗成、

<?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>
View Code

四、从demo中复制struts.xml文件到src文件夹中,

  <struts>标签中所有内容都注释掉,留下以备参考,

  复制<package>的内容,去掉  <default-action-ref name="index" />
  将<action> 标签内容修改如下,

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

  将index.jsp改名hello.jsp

  修改hello.jsp的body内容

<%@ 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>
View Code

 

五、把项目部署到tomcat中

六、访问http://localhost:8080/Struts2_0100/hello.action,其中Struts2_0100为项目名称,hello.action一定要写,可以简写为hello
