Can I use Map<> in query params?

Question

Can I use Map in query params? I have a number of resources for REST and I want to change list of query params in one place, I have a such source:

@GET
@Path("...")
@Produces({MediaType.APPLICATION_JSON})
public String getPath(
        @PathParam("...") String path, 
        @QueryParam("headers") Map<String, String> headers // error!

How to use dynamic list of query params? Because headers will change in the future

and what is the error? But this might help: http://stackoverflow.com/questions/2745265/is-listdog-a-subclass-of-listanimal-why-arent-javas-generics-implicitly-p — Tom, Jul 21 '16 at 13:39

From Oracle's documentation on extracting request parameters, you should be able to use the @Context annotation to pass headers into your method:

@GET
@Path("...")
@Produces({MediaType.APPLICATION_JSON})
public String getPath(
    @PathParam("...") String path, 
    @Context HttpHeaders headers) {
...

and then access the headers and cookies via methods on the HttpHeaders instance. I haven't tried this, but it looks like it should work.
