java出现Error creating bean with name xxController Unsatisfied dependency expressed through fieldxx

今天在写项目时，遇到了一个500的错误，废话不多说，直接上图

错误信息如下：

Error creating bean with name ‘mainController’: Unsatisfied dependency expressed through field ‘movieService’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘com.offcn.movie.service.MovieService’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
翻译为：创建名为“mainController”的bean时出错:通过字段“movieService”表达的不满足的依赖关系;

导致这个错误的原因是因为在movieService接口的实现类里面没有加注解
正确做法是在实现类中加入@Service注解，再刷新一遍问题就解决了。

输入可能飘红线 ，按‘alt’+‘/’ 导入即可。
