如何解决Spring Cloud Gateway 和 Netflix/Eureka - 主机 lb:// 无效？

开发过程中遇到Spring Cloud Gateway 和 Netflix/Eureka - 主机 lb:// 无效的问题如何解决？下面主要结合日常开发的经验，给出你关于Spring Cloud Gateway 和 Netflix/Eureka - 主机 lb:// 无效的解决方法建议，希望对你解决Spring Cloud Gateway 和 Netflix/Eureka - 主机 lb:// 无效有所启发或帮助；

我正在进入 Spring Cloud 2020.0.0 的世界。

我有一个配置服务器、网关服务器、eureka 服务器和第一个微服务设置，并部署在一个开发环境中，它们都可以相互通信。它们是 config-first，并且都成功地从 config 服务器拉下属性源，然后注册到 eureka 服务器。因为我至少现在没有为我的服务应用设置 DNS，所以我有 preferIpaddress: true。

Eureka Instance Registrations

跟踪 spring-cloud-gateway 的日志级别，我看到发现客户端选择了这些 eureka 注册的应用程序：

    2021-01-28 14:49:28.438 DEBUG 14432 --- [           main] o.s.c.g.r.RouteDeFinitionRouteLocator    : RouteDeFinition ReactiveCompositediscoveryClIEnt_CLOUD-serviCES-CONfig applying {pattern=/CLOUD-serviCES-CONfig/**} to Path
    
    2021-01-28 14:49:28.476 DEBUG 14432 --- [           main] o.s.c.g.r.RouteDeFinitionRouteLocator    : RouteDeFinition ReactiveCompositediscoveryClIEnt_CLOUD-serviCES-CONfig applying filter {regexp=/CLOUD-serviCES-CONfig/(?<remaining>.*),replacement=/${remaining}} to RewritePath
    
    2021-01-28 14:49:28.509 DEBUG 14432 --- [           main] o.s.c.g.r.RouteDeFinitionRouteLocator    : RouteDeFinition matched: ReactiveCompositediscoveryClIEnt_CLOUD-serviCES-CONfig
and so on...

在本地运行 API 网关（我也有一个已部署的实例），Postman GET @ http://localhost:8080/DATA-serviCES-PERSON-1_0 导致 Route matched: ReactiveCompositediscoveryClIEnt_DATA-serviCES-PERSON-1_0 以及

我已经查看了几乎所有指南，其中似乎最有意义，因为 2020.0.0 仍然是新发布的。我在这里缺少什么？我已经尝试了几乎所有跟在应用程序名称后面的资源路径，包括一个应该是服务控制器将要访问的资源路径。全部返回到无效主机：lb://..

解决方法

我想通了，这是因为为 DATA-serviCES-PERSON-1_0 注册到 Eureka 的 Spring 应用程序名称有一个下划线。删除/替换该字符解决了问题，现在可以正确路由。

大佬总结

以上是大佬教程为你收集整理的Spring Cloud Gateway 和 Netflix/Eureka - 主机 lb:// 无效全部内容，希望文章能够帮你解决Spring Cloud Gateway 和 Netflix/Eureka - 主机 lb:// 无效所遇到的程序开发问题。

如果觉得大佬教程网站内容还不错，欢迎将大佬教程推荐给程序员好友。
