Description:

Field service in com.demo.springcloud.controller.Controller required a bean of type 'com.demo.springcloud.service.DeptService' that could not be found.


Action:

Consider defining a bean of type 'com.demo.springcloud.service.DeptService' in your configuration.

原因

在控制器类中注入了DeptService类

但是DeptService并没有注册成为Bean，交由Spring容器管理。

解决

在DeptService接口的实现类上添加@Service注解，注册成为Bean。
