在之后添加zuul。

配置：

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=3000

请求控制器：

@HystrixCommand(fallbackMethod="helloFallback")

  

无效

HelloServiceImpl.java

@HystrixCommand(fallbackMethod="helloFallback")
public String helloService() throws InterruptedException {
    ResponseEntity<String> responseEntity = restTemplate.getForEntity("http://eureka-server/helloParam?username={1}", String.class, "didi");
    String body = responseEntity.getBody();

    int sleepTime= new Random().nextInt(4000);
    logger.info("sleepTime:" + sleepTime);
    Thread.sleep(sleepTime);
    logger.info("/hello, host:" + registration.getHost() + ", service id:" +registration.getServiceId());
    return body;    
}


 public String helloFallback() {
        return "error";
 }

现在页面显示

  

com.netflix.zuul.exception.ZuulException：Hystrix读取超时504

我要fallbackMethod返回“错误”；
