使用 com.alibaba.fastjson把json型数据解析成一个javabean

 public class CardQueryResponseBO {

     /**
      * 返回码
      */
     @JSONField(name = "code")
     private String code;

     /**
      * 业务响应
      */
     @JSONField(name = "rsp")
     private CardQueryResponseRspBO rsp;

     /**
      * 业务返回信息
      */
     @JSONField(name = "msg")
     private String msg;

     public String getMsg() {
         return msg;
     }

     public void setMsg(String msg) {
         this.msg = msg;
     }

     public String getCode() {
         return code;
     }

     public void setCode(String code) {
         this.code = code;
     }

     public CardQueryResponseRspBO getRsp() {
         return rsp;
     }

     public void setRsp(CardQueryResponseRspBO rsp) {
         this.rsp = rsp;
     }

     @Override
     public String toString() {
         return JSONObject.toJSONString(this);
     }

 }

使用

CardQueryResponseBO parseResultBean =JSON.parseObject(outParams, CardQueryResponseBO.class);
