两个JSON之间的差异

Question

我正在使用spring MVC来实现返回Object Response

的Web服务

类JAVA Reponse

   @XmlRootElement(name="response")
        public class Response {

        private String request ;
        private List<ListResponse> responses;

         }

类JAVA ListResponse

  @XmlRootElement(name="response")
    public class ListResponse {

    private String param ;
    private List<Param> values;

     }

类JAVA Param

  public class Param {
    private String ID;
    private String VALUE;
    private String LIBELLE;  
    }

Web服务的结果就是这个JSON：

{
 "request": "DEP",
 "response": {
   "param": "DEP",
   "values": [
     {
       "ID": 1000016,
       "LIBELLE": "AIN",
       "VALUE": "010"
     }
   ]
 }
}

但这对我不利，我希望Reponse为List，就像这样

{  
   "request":"DEP",
   "response":[  
      {  
         "param":"DEP",
         "values":[  
            {  
               "ID":1000016,
               "LIBELLE":"AIN",
               "VALUE":"010"
            }
         ]
      }
   ]
}

那么，对此有什么解决方法吗？
