如何修复ZUUL异常转发错误

问题描述 投票：0回答：1

我正在使用 springboot 微服务项目。我有网关、发现和更多项目。 我将其部署在 aws cloud front 容器中。 部署后，我随机遇到一些 zuul 异常。它不是一直发生，而是在我第一次调用 api 时随机发生。第二次工作正常。我只在网关中收到错误。 我们正在使用依赖：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
    <version>2.2.9.RELEASE</version>
</dependency>

错误：

          semaphore:
            maxConcurrentRequests: 2000
        timeout:
          enabled: false

尝试将zuul版本更改为2.2.10.RELEASE和2.2.8.RELEASE，但没有成功。 还尝试更改一些超时，但这也没有成功。

看起来 Zuul 和 Ribbon 是这里的问题

让我解决这个问题

增加 Zuul 和 Ribbon 的连接和套接字超时值。您可以尝试将值增加到比当前值更大的值，看看是否可以解决问题 在 Eureka 配置中将 eureka.client.registerWithEureka 属性设置为 true 这将向 Eureka 注册网关服务，这可能有助于服务发现和路由 在 Ribbon 配置中将 Ribbon.eureka.enabled 属性设置为 false 这将禁用通过 Eureka 的服务发现，并使用 zuul.routes 配置中指定的 URL 如果服务发现或注册出现问题，这会有所帮助 将 hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds 属性设置为更高的值这将增加 Hystrix 命令的超时，如果下游服务响应缓慢，这可能会有所帮助 考虑在下游服务之前使用 NGINX 或 HAProxy 等负载均衡器来分配流量并提高性能 以下是如何根据上述建议修改配置的示例

服务器： 端口：8122 雄猫： 连接超时：180000

管理： 端点： 服务注册表： 启用：真 重新开始： 启用：真 关闭： 启用：真 健康： 启用：真

祖尔： 忽略标头：访问控制允许凭据、访问控制允许来源 主持人： socket-timeout-millis: 600000 # 增加套接字超时 connect-timeout-millis: 600000 # 增加连接超时 路线： 服务一： 网址::8123 服务二： 网址::8124 服务三： 网址: :8125
服务四： 网址::8126 服务五： 网址::8127 丝带： 尤里卡： 急切加载：true enabled: false # 禁用 Eureka 服务发现 丝带： 读取超时：600000 连接超时：1000000 最大自动重试次数：1 最大自动重试下一个服务器：1

尤里卡： 实例： 应用程序名称：发现服务 客户： 服务网址： 默认区域：：8121/尤里卡/ registerWithEureka: true # 向 Eureka 注册网关服务

hystrix： 命令： 默认： 执行： 隔离： 策略：线程 线： 超时毫秒：1000000 信号： 最大并发请求数：2000 暂停： 启用：假

稍后谢谢我 这花了这么长时间
