您可以在FeignClientConfig中添加Retryer

@Configuration
public class FeignClientConfig {

    @Bean
    public Retryer retryer() {
        return new Custom();
    }

}

class Custom implements Retryer {

    private final int maxAttempts;
    private final long backoff;
    int attempt;

    public Custom() {
        this(2000, 3);
    }

    public Custom(long backoff, int maxAttempts) {
        this.backoff = backoff;
        this.maxAttempts = maxAttempts;
        this.attempt = 1;
    }

    public void continueOrPropagate(RetryableException e) {
        if (attempt++ >= maxAttempts) {
            throw e;
        }

        try {
            Thread.sleep(backoff);
        } catch (InterruptedException ignored) {
            Thread.currentThread().interrupt();
        }
    }

    @Override
    public Retryer clone() {
        return new Custom(backoff, maxAttempts);
    }
}

使用基于Retryer.Default的Retryer示例配置进行了更新。

如果使用功能区，则可以设置属性，可以使用以下属性进行重试：

myapp.ribbon.MaxAutoRetries=5
myapp.ribbon.MaxAutoRetriesNextServer=5
myapp.ribbon.OkToRetryOnAllOperations=true

注意：“myapp”是您的服务ID。
查看此Github implementation以获取工作示例

只是新的一个constructor Default

@Configuration
public class FeignClientConfig {
    @Bean
    public Retryer retryer() {
        return new Retryer.Default(100, 2000, 3);
    }
}

如果能帮到人的话就加上这个。我正在使用feign重置连接，因为一些未知的进程正在该端口上运行。尝试更改端口。Refer this to find the process running on a port

我准备了一篇关于使用Spring Retry与Feign Client方法的博客文章。您可以考虑检查Post。所有步骤都在帖子中解释过了。

这是我的配置。在 Spring Boot 2中测试正常。2.0.RELEASESpring Cloud霍克斯顿。M3

feign.hystrix.enabled=true
MY-SPRING-API.ribbon.MaxAutoRetries=2
MY-SPRING-API.ribbon.MaxAutoRetriesNextServer=2
MY-SPRING-API.ribbon.OkToRetryOnAllOperations=true
MY-SPRING-API.ribbon.retryableStatusCodes=404,500

feign.client.config.PythonPatentClient.connectTimeout=500
feign.client.config.PythonPatentClient.readTimeout=500

hystrix.command.PythonPatentClient#timeTest(String).execution.isolation.thread.timeoutInMilliseconds=5000

java代码是：

@FeignClient(name = "MY-SPRING-API",configuration = {PythonPatentConfig.class},fallbackFactory = FallBack.class)
public interface PythonPatentClient 
@RequestLine("GET /test?q={q}")
    void timeTest(@Param("appNo") String q);

控制器为：

@RequestMapping(value = "/test",method = {RequestMethod.POST,RequestMethod.GET})
    public Object test() throws InterruptedException {
        log.info("========important print enter test========");
         TimeUnit.SECONDS.sleep(10L);

pom.xml additon add：

<dependency>
            <groupId>org.springframework.retry</groupId>
            <artifactId>spring-retry</artifactId>
   </dependency>

可选：

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aspects</artifactId>
    </dependency>

@EnableRetry
@SpringBootApplication
public class ApiApplication

我通过在ServiceClient之上创建一个 Package 器解决了这个问题

@Configuration
public class ServiceClient {

@Autowired
ServiceFeignClient serviceFeignClient;

@Retryable(value = { ClientReprocessException.class }, maxAttemptsExpression = "#{${retryMaxAttempts}}", backoff = @Backoff(delayExpression = "#{${retryDelayTime}}"))

public void addPayment( AddPaymentRequest addPaymentRequest){
    return serviceFeignClient.addPayment(addPaymentRequest);
 }    
}
