Spring boot 从Spring引导控制器返回Hystrix AsyncResult

我有以下Spring引导控制器：

@Controller
public class TestController {
    @Autowired
    private TestService service;


    @GetMapping(path="/hello")
    public ResponseEntity<String> handleGet() {
        return service.getResponse();
    }

    @GetMapping(path="/hello/hystrix")
    public Future<ResponseEntity<String>> handleGetAsync() {
        return service.getResponseAsync();
    }

    @GetMapping(path="/hello/cf")
    public Future<ResponseEntity<String>> handleGetCF() {
        return service.getResponseCF();
    }
}

当我点击/hello/cf端点时，我得到一个响应“hello” 当我点击/hello/hystrix端点时，我得到一个404错误

我能以这种方式从控制器返回AsyncResult吗？如果是，我做错了什么

谢谢。

您的服务类需要返回一个完整的未来

另外，除非您使用的是AspectJ，否则如果从同一个类中调用带有@HystrixCommand的方法，断路器将无法工作

精确的代码给了我

{cancelled:false，done:true}

。我看不到404

@Service
public class TestService {
    @HystrixCommand
    public ResponseEntity<String> getResponse() {
        ResponseEntity<String> response = ResponseEntity.status(HttpStatus.OK).body("Hello");
        return response;
    }

    @HystrixCommand
    public Future<ResponseEntity<String>> getResponseAsync() {
        return new AsyncResult<ResponseEntity<String>>() {
            @Override
            public ResponseEntity<String> invoke() {
                return getResponse();
            }
        };
    }

    public Future<ResponseEntity<String>> getResponseCF() {
        return CompletableFuture.supplyAsync(() -> getResponse());
    }
}

@EnableHystrix
@SpringBootApplication
@EnableAsync
public class HystrixApplication {
    public static void main(String[] args) {
        SpringApplication.run(HystrixApplication.class, args);
    }
}
