Question

信息：

spring-cloud.version=Dalston.SR5
spring-boot-starter-parent=1.5.7.RELEASE
zuul-core=1.3.0

当一个客户端的状态为down（我的意思是杀死它），但是zuul也可以有实例信息的缓存，所以请求将路由到down客户端，但是没有正确的响应。所以zuul会重试，路由请求到另一个客户端并获得正确的响应。这种情况就像重新启动我的客户端一样。

所以我有一些配置：

ribbon:
    MaxAutoRetries: 1
    MaxAutoRetriesNextServer: 2
    OkToRetryOnAllOperations: true
    ReadTimeout: 1000
    ConnectTimeout: 250
    ServerListRefreshInterval: 1000
zuul:
  retryable: true

我使用spring-retry jar：

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

但它不像我想的那样有用。所以我调试代码。当zuul路由请求时将使用RetryableRibbonLoadBalancingHttpClient。

的例外情况

org.springframework.cloud.netflix.ribbon.apache.RetryableRibbonLoadBalancingHttpClient#execute
final HttpResponse httpResponse = RetryableRibbonLoadBalancingHttpClient.this.delegate.execute(httpUriRequest);

我在它之后找到了重试代码，因此无法重试逻辑。你能给出一些建议来解决这个问题吗？例外信息：

我建议您添加以下配置并检查它是否有效：

使用功能区时，拒绝连接无法使用重试
