Autowired注入Service失敗!required a bean of type 'com.lncywlc.rio.service.UserService' that could not be

錯誤資訊:
Field userService in com.lncywlc.rio.controller.LoginController required a bean of type ‘com.lncywlc.rio.service.UserService’ that could not be found.

The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type ‘com.lncywlc.rio.service.UserService’ in your configuration.
這個問題主要是馬虎大意造成的。
一定要在實現類中宣告服務 @Service
在這裡插入圖片描述


當然了,如果你的問題並不是忘記宣告服務,可以將
@Autowired 改成 @Resource 試一試
