由于自己平常做项目时喜欢喜欢各种尝试，所有特别多奇葩错误！今天遇到了这个问题搞了半天，在网上也看了下别人的错误，和我的有点不一样，突然想到配置springMvc只配置了controller扫描注入，未配置service扫描注入，所以使用@Autowired无法注入报错!分享一下，也给以后留个答案！
在springMvc文件中配置以下代码就可以了:
<!-- 扫描controller,service（controller,service层注入） -->
<context:component-scan base-package="com.chaoge.controller"/>
<context:component-scan base-package="com.chaoge.service"/>
