问题：

Zuul从数据库服务器获取超过300条记录时抛出“com.netflix.Zuul.exception.zuuleexception:转发错误”

章绪
2023-03-14

你好，特别是乔什·朗爵士！菲律宾的问候！

我只是想就我和祖尔的问题寻求帮助。我正在使用配置服务器、Eureka Discovery、Zuul API网关和身份验证服务，为通过API网关访问资源服务的所有客户开发Spring Cloud微服务。除了通过API网关调用其中一个资源服务（在我的示例书服务中）之外，我所有这些组件都工作得非常好，API网关从数据库服务器获取数据，其中包含300多条记录。netflix。祖尔。例外ZuulException，但如果它获取的数据只有大约100条记录，则可以正常工作


Zuul API网关属性：

server.port=8080

zuul.routes.book-service.path=/book-service/**
zuul.routes.book-service.url=http://localhost:8011
zuul.routes.book-service.serviceId=book-service

security.oauth2.resource.userInfoUri=http://localhost:9192/uaa/me
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=6000

即使我加了希斯特里克斯。命令违约处决隔离线timeoutinmillizes=6000以延长超时时间，但仍然无效。

当我使用Faign Client时，也会引发相同的异常。



这里是堆栈跟踪

只需添加：

ribbon.ReadTimeout=10000

应用。zuul配置文件中的属性。这是我的工作。

异常日志显示异常是由套接字读取超时而不是由Hystrix超时发生的。因此，请尝试添加以下属性

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=10000
ribbon.ReadTimeout=10000               # (1) 
zuul.host.socket-timeout-millis=10000  # (2)

实际上，你只需要（1）或（2）。如果在zuul的routes属性中指定url，它将与SimpleHostRoutingFilter一起使用。在这种情况下，您需要属性（2）。

如果您没有在zuul路由属性中指定url，它将与RibbonRoutingFilter一起工作。在这种情况下，您需要属性（1），因为您的HTTP请求将由ribbon处理。

另外，你的财产和日志看起来不一致。您可以在属性中指定url，但日志显示RibbonRoutingFilter。所以试着把两者都加上。
