點(diǎn)擊啟動APP，報(bào)錯(cuò)No active profile set, falling back to default profiles: default；

APP類的代碼如下：

/**
?*?Hello?world!
?*
?*/
@SpringBootApplication(scanBasePackages??=?{"com.miaoshaproject"})
@RestController
@MapperScan("com.miaoshaproject.dao")
//@EnableAutoConfiguration
public?class?App?
{
????@Autowired
????private?UserDoMapper?userDoMapper;

????@RequestMapping("/")
????public?String?home(){
????????UserDo?userDo?=?userDoMapper.selectByPrimaryKey(1);
????????if(userDo?==?null){
????????????return??"用戶對象不存在";
????????}else?{
????????????return?userDo.getName();
????????}
????}

????public?static?void?main(?String[]?args?)
????{
????????System.out.println(?"Hello?World!"?);
????????SpringApplication.run(App.class,args);
????}
}
