SpringBoot：使用PropertySoucre与外部文件并使用java jar命令时的FileNotFoundException

Question

服务将从eclipse启动，但是如果我开始使用jar命令，同样的事情并不起作用。它只适用于我在属性源中提供绝对路径。我希望属性源能够使用相对路径。

以下是日志，服务的主要类和服务的文件结构

文件结构快照

Answer 1

config目录应该是您拥有review-service.jar文件的位置。把它放在那个jar文件旁边就可以了。

它适用于eclipse，因为在eclipse环境中，应用程序的根目录在你的项目根目录中。在独立版本上，应用程序root是jar文件（或者更确切地说是当前工作目录）的位置
