首先因为没配数据源的问题在Application启动类上加了@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class}),解决启动报错的问题,后来数据源配好忘了去掉,所以后来变报了这个错,花了不少时间找原因。
启动报这个错
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 'xx.xx.dao.UserDao' that could not be found.
Action:
Consider defining a bean of type 'xx.xx.dao.UserDao' in your configuration.
Process finished with exit code 1
一开始以为注入有问题,但@Mapper注解也有,因为用的是idea所以注入时有警告
解决办法在@Mapper下加@Component注解
最后把此前启动类上的@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})改回@SpringBootApplication
启动成功
