JSONObject 转换 JSON复杂对象

Bean定义：

 public class GetM100DataResponse {
     private String service;//接口代码
     private String sessionId;//会话Id
     private String errorCode;//错误码
     private String errorMsg;//错误消息
     private String summary;//摘要

     private List<M100DataObject> dataPoints;    //数据列表

     //get set  略
 }

 public class M100DataObject {
     private String dataType;    //数据类型    String
     private String sendDateTime;    //发送时间    String
     private M100DataObjectKV dataKV;    //数值对象    Object
     private String serviceNo;    //用户服务号    String
     private Integer userSeq;    //用户序号    Integer
     private String eqmtNo;    //设备号    String    

     //get set  略
 }

JSON字符串：

 {
     "dataPoints":[
         {
             "dataKV":{
                 "pulse":"103",
                 "measurementTime":"2015-12-02 12:06:32",
                 "low":"91",
                 "high":"126",
                 "id":"d750fed2-0c95-4722-92ac-3078fa34390b"
             },
             "dataType":"1",
             "eqmtNo":"",
             "sendDateTime":"2015-12-02 12:06:33",
             "serviceNo":"5716b0badb4b426cbfaaebb1be7d57b3",
             "userSeq":"1"
         }
     ],
     "diagResult":"",
     "errorCode":"1",
     "errorMsg":"成功！",
     "propose":"",
     "service":"GET_M100_DATA",
     "sessionId":"1",
     "summary":""
 }

转换代码如下：

 public static JsonConfig getDecodeJSONConfig(){
     JsonConfig jsonConfig = new JsonConfig();
     jsonConfig.registerJsonValueProcessor(String.class, new JsonValueProcessor() {
             public Object processArrayValue(Object value,
                     JsonConfig arg1) {
                 // TODO Auto-generated method stub
                 return process(value);
             }

             public Object processObjectValue(String key,
                     Object value, JsonConfig arg2) {
                 // TODO Auto-generated method stub
                 return process(value);
             }

             public Object process(Object value) {
                 try {
                     if (value instanceof String) {
                         return  URLDecoder.decode(value.toString(),"UTF-8");
                     }
                     return value == null ? "" : value.toString();
                 } catch (Exception e) {
                     return "";
                 }
             }
         }
     );
     return jsonConfig;
 }
 public GetM100DataResponse parseData(String resData){//resData为JSON字符串
     JsonConfig jsonConfig = getDecodeJSONConfig();
     JSONObject json = JSONObject.fromObject(resData, jsonConfig);
     /*
      * 在JSONObject.toBean的时候，如果转换的类中有集合,
      * 可以先定义：Map<String, Class> classMap = new HashMap<String, Class>();
      * 然后在classMap中put你要转换的类中的集合名,如:
      */
     Map<String, Class> classMap = new HashMap<String, Class>();
     classMap.put("dataPoints", M100DataObject.class);//dataPoints 为 属性名称
     /*
      * 然后在toBean()的时候把参数加上, 如:
      */
     GetM100DataResponse response = (GetM100DataResponse)JSONObject.toBean(json, GetM100DataResponse.class, classMap);
     return response;
 }
