Spring Boot未加载bootstrap.properties文件

我注意到，当我创建spring-cloud应用程序时，它仅从application.properties文件（或application.yml）中获取属性，因此我创建了以下演示项目来简化这种情况，但是，我仍然无法从bootstrap.propertiles文件中加载属性。我尝试将bootstrap.properties文件转换为具有相同结果的bootstrap.yml。我尝试以独立方式编译和运行微服务，结果相同。

我将这个项目留在GitHub上以演示情况：https : //github.com/bcfernandez/Mobile-app-ws.git

• 唯一可用的入口点是http：// localhost：port / users / status
• application.properties 文件为空。
• bootstrap.properties文件设置server.port为8181。
• 该应用程序正在端口8080上运行。

该pom.xml如下：

为什么这个简单的项目无法按预期工作？
