JavaEE Web JAX-RS: how to match Query params

JAX-RS allows to match PathParams using regex like this:

@GET
@Path("/users/{username : [a-zA-Z][a-zA-Z_0-9]}")
public Response getUserByUserName(@PathParam("username") String username) {
     ... 
}

But does it allow to match QueryParams as well somehow?

Unfortunately there is no such way of protecting the QueryParams. What you could do is to use an auxiliary method on your server side class to check their values.

@GET
@Path("/myPath")
public Response yourMethod(@QueryParam("code") long code, @QueryParam("description") String desc){
    if(isParametersValid(code,desc)){
        //proceed with your logic
    }else{
       return Response.status(Response.Status.FORBIDDEN).entity("The passed parameters are not acceptable").build();
    }
}  

private boolean isParametersValid(long code, String desc){
    //check
}

You are not allowed to specify regex for QueryParams. As a workaround: just define your own Java data type that will serve as a representation of this query param and then convert this to String if you have to deal with Strings
