该语句是以下意思

(启动ApplicationContext时出错。若要显示条件报告，请在启用“调试”的情况下重新运行应用程序。)

Description:

Field seanceRepository in com.meeting.service.SeanceService required a bean of type ‘com.meeting.dao.SeanceRepository‘ 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.meeting.dao.SeanceRepository‘ in your configuration.

Disconnected from the target VM, address: ‘127.0.0.1:55911‘, transport: ‘socket‘

Process finished with exit code 1

主要报错:

 

 

 Error starting ApplicationContext. To display the conditions report re-run your application with ‘debug‘ enabled.

(启动ApplicationContext时出错。若要显示条件报告，请在启用“调试”的情况下重新运行应用程序。)

 

Consider defining a bean of type ‘com.meeting.dao.SeanceRepository‘ in your configuration.

考虑在配置中定义“com.meeting.dao.seancerepository”类型的bean。

 

Field SeanceRepository in com.meeting.service.SeanceService required a bean of type ‘com.meeting.dao.SeanceRepository‘ that could not be found.

com.meeting.service.SeanceService 中的字段SeanceRepository需要类型为“com.meeting.dao.SeanceRepository”的bean，但找不到该bean。

 

这是SeanceService 调用SeanceRepository时找不到 SeanceRepository 

最简单的解决办法:

在接口上添加@Mapper注解。

@Mapper
public interface UserMapper {
}
