新手学习struts2，启动失败，应该是核心拦截器无法加载
本帖最后由 hao7597566 于 2012-12-12 14:46:40 编辑 我在http://struts.apache.org/下载了Apache Struts 2.3.7 Full Distribution，然后将里面lib的85个jar包都放进测试项目的lib目录里面。
同时对web.xml做了如下配置
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
