Consider defining a bean of type 'xx.xx.dao.UserDao' in your configuration.

首先因為沒配資料來源的問題在Application啟動類上加了@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class}),解決啟動報錯的問題,後來資料來源配好忘了去掉,所以後來變報了這個錯,花了不少時間找原因。 啟動報這個錯

ERROR 13304 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   :

APPLICATION FAILED TO START

Description:

Field userDao in cn.first.service.ServiceImp.UserServiceImp required a bean of type 'cn.first.dao.UserDao' that could not be found.


Action:

Consider defining a bean of type 'cn.first.dao.UserDao' in your configuration.


Process finished with exit code 1

一開始以為注入有問題,但@Mapper註解也有,因為用的是idea所以注入時有警告 Could not autowire. No beans of 'UserDao' type found. more... (Ctrl+F1) 解決辦法在@Mapper下加@Component註解

最後把此前啟動類上的@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})改回@SpringBootApplication 啟動成功
