How do I access a resource file using a relative p

问题:

How do I access a resource file relative to a Play application path (even when packaged into a distribution zip)?

This is the same problem as this, but in Play 2, which has no VirtualFile class in its api.

Thanks.

Check out play.api.Play.getFile() and play.api.Play.getExistingFile(), which get files from the file system relative to the application directory.

A similar technique that works for me is simply to add a resource directory (or jar) to the classpath in the play start script. I can then use Play.getResourceAsStream() to load files from that directory, or specify the resource as a JVM parameter in the start script (e.g. -Dconfig.resource=/my_conf/prd.conf)
