eclipse运行ssh项目出现"HTTP Status 500

1. 在eclipse运行ssh项目出现以下错误信息：

HTTP Status 500 - Unable to instantiate Action.......................

错误信息太多就不写了。

2. 出现以上问题可能是：

在applicationContext.xml配置文件中，把用Repository, Service, Controller注解的bean加到spring容器中， 填写的基包名与项目的基包名不一致。

 

1.  <!-- 把用Repository, Service, Controller注解的bean加到spring容器中 -->  

2. <context:component-scan base-package="base"/>  

此项目本人采用的是struts2+hibernate4+spring4写的

这是我遇到的错误，修改后可用，此方案仅供参考。
