OpenFeign超时控制

超时设置，故意设置超时演示出错情况什么是超时控制YML文件里开启OpenFeign客户端超时控制 为了方便只演示7001/8001，不使用集群，但是是同理的

超时设置，故意设置超时演示出错情况

1、服务提供方8001故意写暂停程序

@GetMapping(value = "/payment/feign/timeout") public String paymentFeignTimeout(){ try { TimeUnit.SECONDS.sleep(3); }catch (Exception e) {e.printStackTrace();} return serverPort; }

2、服务消费方80添加超时方法PaymentFeignService

@Component @FeignClient(value = "CLOUD-PAYMENT-SERVICE") public interface PaymentFeignService { /** * 相当于在消费者Controller和生产者Controller中加了一层Service * * Controller(consumer)--->Service(Feign)-->Controller(Provider) * @param id * @return */ @GetMapping(value = "/payment/get/{id}") public CommonResult getPaymentById(@PathVariable("id") Long id); @GetMapping(value = "/payment/feign/timeout") public String paymentFeignTimeout(); }

3、服务消费方80添加超时方法OrderFeignController

@GetMapping(value = "/consumer/payment/feign/timeout") public String paymentFeignTimeout(){ return paymentFeignService.paymentFeignTimeout(); }

4、http://localhost/consumer/payment/feign/timeout

什么是超时控制

OpenFeign默认等待一秒钟，超过后报错

OpenFeign默认支持Ribbon

YML文件里开启OpenFeign客户端超时控制

ribbon: ReadTimeout: 5000 ConnectTimeout: 5000
