原因两个：（当时我是第二个）

1.lib中多导入包的大原因：去掉struts2-spring-plugin-2.1.8包即可，因为没有用到spring。

2.还有的原因是用spring了，却没加监听器，在web.xml里面加上

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext*.xml</param-value>

</context-param>

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>
