服务远程调用成功但还是404

Question

​
今天在做谷粒学院的项目,用到远程调用,被调用的服务sql都执行了,但就是不知怎么滴就是说404

@FeignClient(name = "service-ucenter")
@Component
public interface UcenterClient {
     @GetMapping("/ucenter/member/countRegister/{day}")
     R countRegister(@PathVariable("day") String day);
}

 到方法内第一行就卡住了

@Service
public class StatisticsDailyServiceImpl extends ServiceImpl<StatisticsDailyMapper, StatisticsDaily> implements StatisticsDailyService {
    @Autowired
    UcenterClient ucenterClient;

    @Override
    public void registerC1ount(String day) {
        R r = ucenterClient.countRegister(day);
        Integer count = (Integer) r.getData().get("countRegister");

 这个被调用的方法的sql执行了,也能获取到结果

@RequestMapping("/ucenter/member")
@CrossOrigin
@Controller
public class UcenterNumberController {
    @Autowired
    MemberService memberService;
    //查询某一天的注册人数
    @GetMapping("/countRegister/{day}")
    public R countRegister(@PathVariable("day") String day){
        Integer integer = memberService.countResister(day);
        System.out.println(integer+"memberService.countResister(day)");
        return R.ok().data("countRegister",integer);
    }
}

 这是报错信息

你的controller 要么在方法上加上 @ResponseBody 注解，要么把 @Controller 换成 @RestController
