spring-boot客户端无法从Consult启动

Question

我已使用docker在系统上使用以下命令设置并运行Consult：

sudo docker run -p 8500:8500 consul:0.9.2

Consult运行良好，我可以从Consult UI中查看（图片附在下面）：

现在，我正在尝试运行我的spring-boot服务，以便使用这个Consuler实例进行服务发现和注册。但是，每当我启动时，它会给我以下例外情况：

Answer 1

通过将Consult服务器和端口配置从application.yml移动到bootstrap.yml，我能够解决我的问题。

我不太了解它是如何解决的，以及为什么它不能从application.yml读取。如果有人有关于它的一些细节，PL。让我知道。
