Best Practices

User-Specific Properties Files

You can have any number of Properties.username files in your project's Resources directory in-addition-to the default Properties file. These Properties.username files will automatically load based on which user is launching the application. This allows you to have custom logging, email, database, etc configuration settings for each developer.

This capability can also be (ab)used in combinination with the Launch parameter -Duser.name to specify Production vs Staging/Development properties. For example: a launch parameter of -Duser.name=deployment will cause Properties.deployment to be read when the application in launched.

This can be very useful for automatically changing database connection configurations based on whether or not an application is being run in Production or Development.
