how to get all *.json files in a jar programatically?

Question

say under my src/main/resources folder I have several .json files, how can I write java code to retrieve a list containing all those files?

it seems that getClass().getClassLoader().getResources doesn't support wildcard matching.

Not sure if this is worth an answer given the duplicates, but you can use this answer to get a list of resource files from the JAR, and then while iterating though the list check if the file is a json file using zip.getNextEntry().getName().endsWith(".json")... if it is, add it to your new list.
