在SSH整合项目时候出现以下问题

原来问题出在这个文件的配置，该文件明确表明了会检索以action,actions,struts,struts2的名字检索对应的jar包，那么org.apache.struts.Action自然而然会被解析。

发生异常也是理所当然的，那么我们打开自己的struts.xml文件修改常量，因为项目的struts.xml的配置是高于

插件配置的，更改如下:

<constant name="struts.convention.package.locators" value="actions,struts2"/>

表示插件只对actions和struts2包感兴趣，于是乎异常被解决了。
当然如果表示对使用（struts-convention-plugin.jar）压力很大的童鞋们，可以考虑直接删除该jar包不使用，异常一样可以解决。

发生这个异常也不要想当然的认为将所有Action类得名字中去除Action关键字就能解决。
