RestEasy : GET request with multiple dynamic arguments

Question

The required URL should be something like this :

http://<host>:<port>/path/item?<arguments>

The arguments key and value supposed to be multiple and dynamic, so I cannot use @BeanParam or @QueryParam. Also I can only call this interface without implementation.

My current code is something like this :

public interface RestService {

    @GET
    @Path("/path/item")
    @Produces(MediaType.APPLICATION_JSON)
    public JsonNode method(@QueryParam("params") String params);
}

Example of arguments that I want to pass : brand=myBrand&price=myPrice

Is there any way to do something like this ?

Answer 1

Use UriInfo.getQueryParameters(), as following:

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

It returns a MultivaluedMap. Then just iterate over it.
