REST Web Service - Dynamic Query Parameters

Question

I have a requirement to send dynamic query parameters to REST web service GET method [as shown below].

host:port/app?field1=XXX&value1=VVV&field2=XXX&value2=XXX ....

The consumer can send parameters up to fieldn and valuen. Each field maps to the value.

With this type of requirement, I can't code a finite set of QueryParams on the server side method.

Is there any type of REST library that supports this? I checked RESTEasy and Jersey, and they both don't seem to support this [as far as I checked].

Thanks.

jersey sure does, check stackoverflow.com/questions/6154861/… — user311174

Thanks for your response. But that solution is for getting query parameters of same name. But in my case, the names will be different as in field1, field2, field3 and so on. — Arav Vijay

Use UriInfo.getQueryParameters(), as following:

@GET
@Path("/foo")
@Produces(MediaType.APPLICATION_JSON)
public Response foo(@Context UriInfo uriInfo) {
    MultivaluedMap<String, String> queryParams = uriInfo.getQueryParameters(); 
    ...
}

It returns a MultivaluedMap. Then just iterate over it.
