出现这样的请景一般就是RestTemplate执行网络超时或者是微服务之间网络调用超时熔断

解决方式：1、调长网关熔断时间

ribbon.ConnectTimeout=20000
ribbon.ReadTimeout=20000
zuul.host.socket-timeout-millis=20000
zuul.host.connect-timeout-millis=20000
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=20000

2、配置RestTemplate连接时间

SimpleClientHttpRequestFactory simpleClientHttpRequestFactory = new  SimpleClientHttpRequestFactory();
     simpleClientHttpRequestFactory.setConnectTimeout(20000);
     simpleClientHttpRequestFactory.setReadTimeout(30000);
     restTemplate = new RestTemplate(simpleClientHttpRequestFactory);
