如何解决Timeout FeignClient

Question

使用在SQL Server中执行查询的服务时,我的应用程序遇到错误FeignClient.

错误:

线程"pool-10-thread-14"中的异常feign.RetryableException:读取超时执行GET http://127.0.0.1:8876/processoData/search/buscaProcessoPorCliente?cliente=ELEKTRO+-+TRABALHISTA&estado=SP

我的消费者服务:

@FeignClient(url="http://127.0.0.1:8876")
public interface ProcessoConsumer {

@RequestMapping(method = RequestMethod.GET, value = "/processoData/search/buscaProcessoPorCliente?cliente={cliente}&estado={estado}")
public PagedResources<ProcessoDTO> buscaProcessoClienteEstado(@PathVariable("cliente") String cliente, @PathVariable("estado") String estado);

}

我的YML:

server:
  port: 8874

endpoints:
  restart:
    enabled: true
  shutdown:
    enabled: true
  health:
    sensitive: false

eureka:

  instance: 
    preferIpAddress: true

ribbon:
  eureka:
    enabled: true

spring:
  application:
    name: MyApplication
  data:
    mongodb:
      host: xxx.xx.xxx.xx
      port: 27017
      uri: mongodb://xxx.xx.xxx.xx/recortesExtrator
      repositories.enabled: true
    solr:
      host: http://xxx.xx.xxx.xx:8983/solr
      repositories.enabled: true

有谁知道如何解决这个问题？

谢谢.

Answer 1

在Application.properties文件中添加以下属性.

feign.client.config.default.connectTimeout: 160000000
feign.client.config.default.readTimeout: 160000000

Answer 2

我正在使用Feign.builder()实例化我的 Feign 客户端。

为了设置connectTimeoutand readTimeout，我使用以下内容：

Feign.builder()
     ...
     .options(new Request.Options(connectTimeout, readTimeout))
     .target(MyApiInterface.class, url);

使用它我可以为不同的 API 配置不同的超时。

Answer 3

刚刚也遇到了这个问题。正如@spencergibb 所建议的，这里是我正在使用的解决方法。见链接

在 application.properties 中添加这些。

# Disable Hystrix timeout globally (for all services)
hystrix.command.default.execution.timeout.enabled: false

# Increase the Hystrix timeout to 60s (globally)
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 60000

Add this in the Java configuration class.

import feign.Request;

@Configuration
@EnableDiscoveryClient
@EnableFeignClients(basePackageClasses = { ServiceFeignClient.class })
@ComponentScan(basePackageClasses = { ServiceFeignClient.class })
public class FeignConfig {

    /**
     * Method to create a bean to increase the timeout value, 
     * It is used to overcome the Retryable exception while invoking the feign client.
     * @param env,
     *            An {@link ConfigurableEnvironment}
     * @return A {@link Request}
     */
    @Bean
    public static Request.Options requestOptions(ConfigurableEnvironment env) {
        int ribbonReadTimeout = env.getProperty("ribbon.ReadTimeout", int.class, 70000);
        int ribbonConnectionTimeout = env.getProperty("ribbon.ConnectTimeout", int.class, 60000);

        return new Request.Options(ribbonConnectionTimeout, ribbonReadTimeout);
    }
}

看看这个答案。它对我有用。我还做了一些研究，在这里找到了属性文档：
