OpenFign-超时处理

OpenFign-超时实现

OpenFign调用超时实现步骤：
1.provider     timeout处理 改controller
2.Consumer timeout处理 改service 和controller
3.改application.yml配置

OpenFign调用超时实现步骤：
1.provider     timeout处理 改controller
 

@RestController
@Slf4j
public class PaymentController
{
 @GetMapping(value = "/payment/feign/timeout")
    public String paymentFeignTimeout()
    {
        // 业务逻辑处理正确，但是需要耗费3秒钟
        try { TimeUnit.SECONDS.sleep(3); } catch (InterruptedException e) { e.printStackTrace(); }
        return serverPort;
    }
}
 

2.Consumer timeout处理 改service 和controller
    service 

@Component
@FeignClient(value = "CLOUD-PAYMENT-SERVICE")
public interface PaymentFeignService
{
    @GetMapping(value = "/payment/feign/timeout")
    public String paymentFeignTimeout();
}
 

controller
@RestController
@Slf4j
public class OrderFeignController
{
    @Resource
    private PaymentFeignService paymentFeignService;
 
    @GetMapping(value = "/consumer/payment/feign/timeout")
    public String paymentFeignTimeout()
    {
        // OpenFeign客户端一般默认等待1秒钟
        return paymentFeignService.paymentFeignTimeout();
    }
}

3.application.yml文件
 

#设置feign客户端超时时间(OpenFeign默认支持ribbon)
ribbon:
  #指的是建立连接所用的时间，适用于网络状况正常的情况下,两端连接所用的时间
  ReadTimeout: 5000
  #指的是建立连接后从服务器读取到可用资源所用的时间
  ConnectTimeout: 5000

openFeign解决服务间调用超时问题

解决

1、 新建配置类 ServiceFeignConfiguration

import feign.Request;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ServiceFeignConfiguration {

    @Value("${service.feign.connectTimeout:60000}")
    private int connectTimeout;

    @Value("${service.feign.readTimeOut:60000}")
    private int readTimeout;

    @Bean
    public Request.Options options() {
        return new Request.Options(connectTimeout, readTimeout);
    }
}

 

2、在需要使用 feign 的接口上使用配置

import com.landscape.landscape.service.user.config.ServiceFeignConfiguration;
import com.landscape.landscape.service.user.service.fallback.FeignImServiceFallback;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;

@Component
@FeignClient(value = "landscape-service-im", configuration = ServiceFeignConfiguration.class, fallback = FeignImServiceFallback.class)
public interface FeignImService {

  
    @PostMapping("/im/user/import")
    String importUser(@RequestBody String json);
}
