List of all (also optional) query parameters in java rest web service

Question

I want to have all query parameters in a list. As well those that were not used in the get method. My method:

@GET
@Produces({"text/csv"})
@Path("/somesearch/")
public Response method1(
        @DefaultValue("0") @QueryParam("param1") float param1,
        @DefaultValue("0") @QueryParam("param2") float param2,
        // further optional parameters... not only floats){
    ArrayList<Object> parameters = new ArrayList<Object>();
    parameters.add(param1);
    parameters.add(param2);
    // add further query parameters
    // do something ...
 }

so is there a possibility to obtain all the parameters (even those not set in the GET request) in a list? I can't use the @context uriInfo with its getQueryParameters() method because it lists the parameters used in the url

Answer 1

Not sure about the @DefaultValue annotation, but if I had to do it I would have done it something like this..

 @GET
    @Produces({"text/csv"})
    @Path("/somesearch/")
    public Response method1(@Context UriInfo uriInfo){
        MultivaluedMap<String, String> multiParameters = uriInfo.getQueryParameters();
       // multiParameters contains all the parameters in key-value pairing format
     }
