How can i have such user friendl开发者_开发知识库y urls.

I guess you are looking for Representational State Transfer (REST)

you need to use a technology named URL Rewrite, usually people put a nginx in front of tomcat, so the nginx get the request:

and nginx forward a url to tomcat which tomcat can understand:

or if you want pure java solution, then take a look at:
