搭建struts2+tomcat 开发环境

1.本着穿一手鞋的原则去struts官网上载struts-2.3.15.1-all

2.环境准备由于我比较赖直接用myeclipse

3.struts-2.3.15.1-all\struts-2.3.15.1\apps\struts2-blank.war 这个是基本的把它解压

（1）struts2-blank\WEB-INF\lib strut2用的jar包 搞定

（2）struts2-blank\WEB-INF\web.xml 复制一下

（3）WEB-INF\classes\example.xml 和 struts.xml 复制到根目录src 复制 jsp java 类

4.myeclipse 新建项目

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

5.部署一下tomcat

访问一下地址：http://localhost:9999/struts2/example/HelloWorld.action 好吧可以了。
