同学好，跟监听器无关吧。。主要异常是

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.imooc.o2o.service.ShopCategoryService' available: expected at least 1 bean which qualifies as autowire candidate.

ShopCategoryService 没有实现类，或者实现类头部没有添加@Service标签。。

同学好，出现的是哪个错误？是这个？org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.imooc.o2o.service.ShopCategoryService' available: expected at least 1 bean which qualifies as autowire candidate. 这个的话就是说的是接口找不到对应的实现类bean呢，如果还是这个，难道是扫描的时候没有扫到你的实现类？
