<!-- 自动扫描controller bean，把作了注解的类转换为bean -->
<context:component-scan base-package="com.controller" />
这个配置你改一下，对了还想说一下，目录结构的package名最好起成三段式，eg：com.xxxx.dao com.xxxx.service

你说的这个错误我改过了 就是帮测试类中 @Resource 后面那个("stuService") 删掉了
然后就又报下面错误

serviceImpl类写的没必要，还有，你就没注意一下这个错误？
No bean named 'stuService' is defined
