Spring Boot (ConfigServer) 一直在重新启动
Spring Boot (ConfigServer) is restarting all the time
我们有一个非常简单的 Spring 引导服务 (@EnableConfigServer) 运行 在 nginx 代理后面。
服务基本正常，但一直在重启（context关闭后不断启动）
在此处查看日志文件：http://pastebin.com/GErCF5x6
设置基本上只有一个 Java Class 和两个配置（bootstrap.properties 以及 application.properties）。

所以，配置服务器没有重新启动。它使用一个新的 Spring 应用程序上下文并将它从 git 抓取的文件加载到一个新的上下文中，并对值进行格式化以发送回客户端。以下是来自我的配置服务器的一个客户端连接的日志。日志看起来很混乱，好像正在重新启动。

这很正常。启动和停止的不是应用程序，它只是用于为远程客户端创建配置资源的微型上下文。完全无害。
我在这里发现了我面临的问题。基本上，我们在 AWS 上有两个远程服务 运行 和一个已配置的 Load Balanacer，它会持续检查 /health 端点。通过调用此方法，ConfigServerClient 始终调用我们的 ConfigServer。
我不明白为什么 ConfigServer 有一个 HealthIndicator，有没有办法禁用这个 HealthIndicator，因为对该端点的每个请求都会一次又一次地查询我们的配置服务器。另一个缺点是，/health 请求不再尽可能快地响应，这会导致负载均衡器超时（默认 2s）。
