看到同学的同学的controller是在com.imooc.controller包下是吗?

http://img1.sycdn.imooc.com//climg/5c764b1e000164b803030047.jpg

建议把包路径改成：com.imooc.sm.controller 试试，因为同学在配置文件中就是扫描的这个包。有可能是controller没有被注解扫描到从而没有交给spring

如果我的回答解决了你的疑惑，请采纳！祝学习愉快！

    配置代码写的也是没有问题，还有一个可能是，你的spring.xml文件有没有放到resource文件夹中呢？如果没有建议你放到resource文件中试试。祝学习愉快~
