Answer 1

Actually, the most easiest way is to put application.properties and your.jar into the same directory, and just java -jar your.jar will automatically load this external config file.

And if you are trying to load some context/files from resource folder via ClassPathResource, when you read the file don't use pathResource.getFile(), instead use pathResource.getInputStream(), getFile() works well within your IDE, however it doesn't work with the standalone jar.
