我在Mac OS X上运行spring cloud配置服务器的简单演示。应用程序具有本机作为活动配置文件，并使用本地文件夹作为配置文件而不是git。当我启动应用程序时，它抛出异常：

Answer 1

一般情况下，当maven下载依赖项时，弹出的那些错误会出错。要解决这个问题，请从borked依赖项中清除本地存储库。

你基本上有两种解决方法

直接删除完整的~/.m2/repository目录，删除所有本地依赖项
从mvn dependency:purge-local-repository目录中删除所有项目依赖项的细微~/.m2/repository。

之后只需重新构建应用程序mvn package即可再次下载依赖项。

Answer 2

在application.yaml的最后一行使用searchLocations而不是搜索位置。
