如果你的struts.xml和applicationContext.xml都配置正确,还报以上的错误,那么可以判断你的项目缺少jar包：
struts2-spring-plugin-2.0.11.1.jar、commons-fileupload-1.2.1.jar和commons-io-1.3.2.jar
导入这些jar包就行了,这些jar可以在struts-2.2.1的lib下找到.
在搭工程的时候,commons-fileupload-1.2.1.jar和commons-io-1.3.2.jar要是忘记了,报错很容易就看出来少哪些jar包,
但是struts2-spring-plugin-2.0.11.1.jar不太容易发现.
