FastJson之JsonObject, JsonString, JavaBean,List快速转换

 
// 将json字符串转换为json对象
 JSONObject jsonObject = JSON.parseObject(jsonStr);     //  {"retState":"SUCCESS","retCode":"000000","retMsg":"成功", "data":[{"id":2150,"name":"合肥市","address":null}],"total":0}

// json字符串转java对象
 String data = jsonObject.getString("data");
 ComboxResponse city = JSON.parseObject(data, List<ComboxResponse>.class);

// json字符串转List集合
 ComboxResponse city = JSON.parseArray(data, ComboxResponse.class).get(0);
