我正在对一组 Spring Cloud + Netflix OSS 应用程序进行原型设计，但在使用 Eureka 时遇到了麻烦。在我们的设置中，我们有一个 Spring Cloud Config Server + Eureka Server，然后是 2 个利用该服务器组件进行引导和服务发现的模块。
我遇到的问题是，如果我启动 2 个 Eureka Server 实例并尝试将它们配对（基于文档中的Two Peer Aware Eureka Servers），它们不会相互同步。请参阅下面的配置和/或GitHub 上的代码。
本质上，Peer1 启动并且看起来很好。Peer2 将启动并且看起来很好，两个对等点在服务中相互显示。但是，如果“UserService”模块启动并向 Peer1 注册自身，Peer2 将永远看不到它。如果我们随后启动指向 Peer2 的“Web”模块，它永远无法解析 UserService。他们基本上是孤立地行动。
我尝试了几种serviceUrl在服务器和 Eureka 服务器实例上设置的组合，但无济于事。我只是配置错误吗？
