解决方案

您已将 application.properties 文件外部化。有多种方法可以解决这个问题，我在下面写下其中两个：---

第一种解决方法：--

创建一个配置文件夹，在其中放置 jar 文件 n 将 application.properties 放入配置文件夹中。

Ex- 
if your jar is inside /home/user folder
then your property file should be inside /home/user/config/application.properties

然后运行：

java -jar <yourjar>

第二种解决方法：--

给出正确的路径位置：--

java -jar <yourjar> --spring.config.location=<property file path>
