补充信息：

老师你好，我在尝试添加验证码图片的时候出现了报错，错误如下：

例外情况
javax.servlet.ServletException: Servlet[spring-dispatcher]的Servlet.init（）引发异常

根本原因:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'shopManagementController': Unsatisfied dependency expressed through field 'shopService'; 
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.imooc.o2o.service.ShopService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

根本原因：
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.imooc.o2o.service.ShopService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

同时，在添加了 kpatch 之后， ShopManagementController.java 中也出现了新的 wrong message：

1. Could not autowire. No beans of ‘ShopService’ type found.
2. Could not autowire. No beans of ‘ShopCategoryService’ type found.
3. Could not autowire. No beans of ‘AreaService’ type found.

我尝试了这个文章和评论中的方法，在视频4-5的时候可行，但是这一次都不行了：https://blog.csdn.net/u012453843/article/details/54906905

路径和文件名都没有问题，ShopManagementController 我也仔细对比了没有问题，目前不知道如何定位我的问题，不太清楚 “NoBeanAvailable" 要如何解决。

麻烦老师分析下，下一步应该从哪里 Debug？谢谢老师
