You need to pass the path to your file properties into a jvm using -D 您需要使用-D将文件属性的路径传递到jvm中
-Dname=$pathto yourjar anyargs..
you can get it in your application likethis : 您可以像这样在应用程序中获取它:
String location = System.getProperty(name);
You should be able to do it just like any other. 您应该能够像其他任何人一样去做。 See this on how to generate a jar file: Java creating .jar file
