描述：
启动类中有加注解mapperscan:
@MapperScan("com.naughty.userlogin02.dao")
@SpringBootApplication
public class Userlogin02Application {
public static void main(String[] args) {
SpringApplication.run(Userlogin02Application.class, args);
}
}

再启动：
虽然能启动了但是还有报错
mapper[com.naughty.userlogin02.dao.ExamManageMapper.findAll] is ignored, because it exists, maybe from xml file
另外要记得service中有加注解：
