下面举一个代码的列子目的是实现如下功能:
[{"userId":1,"userName":"plf"},{"userId":2,"userName":"phy"},{"userId":3,"userName":"ply"}]
变成
[{"user_id":1,"user_name":"plf"},{"user_id":2,"user_name":"phy"},{"user_id":3,"user_name":"ply"}]
我们可以通过如下的代码实现：
public JSONArray getNewJSONArray(JSONArray array){ JSONArray a1=new JSONArray(); JSONObject aa=new JSONObject(); for(int i=0;i<array.size();i++){ JSONObject a= (JSONObject)array.get(i); Iterator itt = a.keys(); Set set=a.keySet(); List list=new ArrayList(set); for(int j=0;j<list.size();j++){ aa.put(isAcronym(list.get(j)+""), a.opt(list.get(j)+"")); } a1.add(aa); } return a1; }
//利用函数将userId-->>user_id public String isAcronym(String word) { StringBuffer words = new StringBuffer(); for (int i = 0; i < word.length(); i++) { char c = word.charAt(i); if (!Character.isLowerCase(c)&&i!=0) { String w=c+""; w="_"+w.toLowerCase(); words.append(w); }else{ words.append(c); } } return words.toString(); }
