Consider defining a bean of type 'com.ge.information.mapper.UserMapper' in your configuration.

解决办法：

一：加入@MapperScan(value="com.ge.information.mapper")

@MapperScan(value="com.ge.information.mapper")
public class InformationApplication {

    public static void main(String[] args) {
        SpringApplication.run(InformationApplication.class, args);
    }

}

或者二：加入

@Mapper

@Mapper
public interface UserMapper extends BaseMapper<UserEntity> {xxx}
