How to get a path name as a parameter in JAX-RS @Path

Question

I want to create a REST service where the parameter is a path with a non-fixed number of terms. For example:

@Path("obj") public class ObjectResource { @GET @Path(???) public Response getObj(@Param(???) String path) { .... } }

If the request URL is like:

http://myhost.xyz/app/obj/var/share/www

The method getObj would get as its path parameter the String

var/share/www

Alternatively it would be OK to get an array (or Collection) with "var" "share" "www" in separate ordered elements. (I would just do a String.split() on the single string anyway.)

Can this be done?

@RomanVottner Well that was absurdly easy. If you want to write that up as an answer I'll mark it for you. — AlanObject

You can try with PathSegment.

@Path("obj") public class ObjectResource { @GET @Path("{var: \\.+}") public Response getObj(@PathParam("var") final PathSegment path) { final String value = path.getPath(); } }

Edit: What actually works is the following:

@GET @Path("obj") public class ObjectResource { @Path("{part: .*}") @Produces(MediaType.APPLICATION_JSON) public Response getObj(@PathParam("part") String pathpart) { // just return the path return Response.ok(pathpart).build(); } }
