问题
My code:
BufferedInputStream bis =
new BufferedInputStream(getClass().getResourceAsStream("playerhit.mp3"));
This code works fine when the playerhit.mp3 file is in same package as the MP3.classit is running in. I'm running this as .jar. If though I change the file path to something like /src/data/audio/playerhit.mp3 it doesn't work anymore. Is there anyway to access different filepath than root of the package while running as .jar?
回答1:
Take a look at the Javadoc for getResourceAsStream(...).
If the argument begins with a /, then the absolute name of the resource is the portion of the name following the /. Otherwise, the absolute name is of the following form:
modified_package_name/name
Where the modified_package_name is the package name of this object with / substituted for ..
So, if your playerhit.mp3 is in the root of your package structure, you should reference it as /playerhit.mp3. If it's in /src/data/audio/, you should probably use /data/audio/playerhit.mp3 - but check the contents of your JAR file to be sure.

Check first if the file is actually in the jar.
Check the location inside the jar.
Relative path: current package
Absolute path: root of jar
