json字符串拼接(目前使用过两种方式)：

1.运用StringBuilder拼接

StringBuilder json = new StringBuilder();

json.append("{");

json.append("\"uuid\":" + "\"" + uuid + "\",");

json.append("\"phone\":" + "\"" +

list.get(i).get("DEST_NUMBER") + "\",");

json.append("\"tempTypeId\":\"6\",");

json.append("\"tempStatus\":\"0\",");

json.append("\"account\":" + "\"" +

list.get(i).get("DEST_NUMBER") + "\",");

json.append("\"amount\":" + "\"" +

Integer.parseInt(list.get(i).get("AMOUNT") + "") / 100 +

"\",");

json.append("\"result\":\"0\",");

json.append("\"source\":\"JF\",");

json.append("\"first\":\"\",");

json.append("\"url\":\"\",");

json.append("\"remark\":\"\"");

json.append("}");

String jsonstr = json.toString();

2.运用JSONArray(JsonObject)

JSONObject jo= new JSONObject(); //

对象{}

JSONArray json = new JSONArray();// 数组[]

jo.put("id",

Convert.convertNull(hm.get("cost_center_id")));

jo.put("Pid",

Convert.convertNull(hm.get("parent_center_id")));

jo.put("name",

Convert.convertNull(hm.get("cost_center_name")));

jo.put("isParent",

Long.parseLong(Convert.convertNull(hm.get("count"))) > 0 ? true

: false);

jo.put("levelId",Convert.convertNull(hm.get("level")));

String jsonObj = jo.toString();

json.put(jo);

String jsonArr = json.toString();

json解析：

1.List idList = (List)

JSONUtil.deserialize(agreementIds);

2.运用JSONObject

注：

json.append("msg", "a1")

json.append("msg", "a2")

{"msg":["a1", "a2"]}

---数组追加

json.put("msg", "a1")

json.put("msg", "a2")

{"msg":"a2"}

---ojbect替换
