Class.getResource在错误的jar中查找资源

Question

• ClassA is located within JarA
• ResourceA is located within JarA
• ResourceB is located within JarB

Both jars are in the classpath.

ResourceA and ResourceB have the same path within their respective jars, ie "resources/somefile.txt"

Using:

ClassA.class.getResource("resources/somefile.txt");

I would expect to always get ResourceA however I am getting ResourceB.

Is this expected behaviour, and if so is there any way to garauntee returning ResourceA in this scenario?

Thanks in advance.

Answer 1

This is related to classloaders. One trick to overcome such issue is to use something like this:

A.class.getClassLoader().getResource("/yourResources")

Where A is some class in the desired archive.
