feign.FeignException：在微服务调用中读取状态 404

Question

当我像这样调用微服务 rest api 时：

Response<List<RoomPlay>> response = reportRoomHappyBombDetailController.happybombRoomDetailAnalysis(BizAnalysisConstant.DEFAULT_ANALYSIS_PREV_DAY, roomPlay.getId());

抛出此错误：

2020-04-01 23:46:00.954 ERROR 1 --- [cTaskExecutor-1] c.s.s.r.c.room.RoomCreateMessageHandler  : 统计执行遇到问题

这是我的服务器端代码：

@RequestMapping(value = "/analysis/app/happybomb/room")
@FeignClient(name = "soa-report-analysis-service")
public interface IReportRoomHappyBombDetailController {
    @GetMapping("/overview")
    Response<List<RoomPlay>> happybombRoomDetailAnalysis(@RequestParam(required = false, defaultValue = "2", value = "lastDay") Integer lastDay,
                                                         @RequestParam(required = false, value = "roomPlayId") Long roomPlayId);
}

服务可以成功接收请求和响应，但是客户端抛出这个错误messsage.I我很困惑哪里出了问题？Spring引导版本2.1.3，Spring云Version:Greenwich.SR1.

将实现此接口的注释由@Controller更改为@RestController，或添加@ResponseBody注释。有效！
