1 format1：

// 转换成object
JSONObject jo = JSON.parseObject(result);      
// 获取object中returnAddress字段;     
jo.getString("returnAddress");                                          

2 format2

JSONArray detail = JSON.parseArray(result);
for (int i=0; i<detail.size();i++){if(detail.get(i)!=null||!detail.get(i).equals("")){JSONArray detailChild =detail.getJSONArray(i);if(detailChild.getInteger(1)>Integer.valueOf(ship.get("shiptime").toString())){ship.put("shiptime",detailChild.getInteger(1));ship.put("desc",detailChild.getString(0));}}
}

3 JSON转Bean

JSONobject=>javaBean

JSONObject contentChild = contentsArray.getJSONObject(i);
QCCustomerScore.CustomerCore customerCore = JSON.toJavaObject(contentChild, QCCustomerScore.CustomerCore.class);

String转javaBean
