解决问题步骤：
第一，看看是否导入Junit4这个单元测试包没，没有导入再运行。否则进入第二步
第二，jar包冲突，检查项目中的jar包是否同时有
xerce.jar和xml-apis.jar这两个jar包，有的话删除xerce.jar
第三，缺了包，检查struts.xml中是否有配置
有的话看看项目中是否有引入struts2-spring-plugin-2.1.6.jar，没有的话引入即可

这个问题只要你机子联网就可以跑起来,但是你一没网就报错了..具体如下:

解决办法：解决不联网无法启动struts2问题
*将struts.xml中的声明部分
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD StrutsConfiguration 2.1//EN"
"http://struts.apache.org/dtds/struts-2.1.dtd">
替换为 在struts2-core-2.xxx.jar包中struts-default.xml的文件声明
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD StrutsConfiguration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
****说白了也就是说要保持一致！！
