从Restlet请求获取HTTP GET参数

Question

I am trying to figure out how to get the parameters from a Restlet request object.

my request comes in as /customer?userId=1 and I want to grab the parameter to pass to my DAO for the query.

public class CustomerResource extends ServerResource
{
  @Get("xml")
  public Representation toXml() throws ResourceException, Exception
  {
      try
      {
          //get param from request
         //call DAO with parameter
      }
      catch(Exception e)
      {
          throw e;
      }
  }
}

Please not that there is a shortcut method for that:

String paramValue = getQueryValue("userId");

Hope it helps you.
