這篇文章主要介紹了Java中如何將String轉(zhuǎn)JSONObject,String類型轉(zhuǎn)JSONObject，下面有兩種方式可以進(jìn)行轉(zhuǎn)換，本文結(jié)合實(shí)例代碼給大家介紹的非常詳細(xì)，需要的朋友可以參考下

String轉(zhuǎn)JSONObject

String類型轉(zhuǎn)JSONObject，下面有兩種方式可以進(jìn)行轉(zhuǎn)換

1、使用alibaba的com.alibaba.fastjson.JSONObject進(jìn)行轉(zhuǎn)換

2、使用org.json.JSONObject進(jìn)行轉(zhuǎn)換

轉(zhuǎn)換完成后，獲取key中的value值，如下代碼：獲取result中的realtime的值，可以將其轉(zhuǎn)換成string也可以將其轉(zhuǎn)成JSONObject

String jsonStr= jsonObject.getJSONObject("result").get("realtime").toString();

Java將String轉(zhuǎn)換成json對象或json數(shù)組

這里的SmartProejctEquipmentMap 是我自定的一個實(shí)體類，可以自己定義轉(zhuǎn)換。

注意：json字符串中鍵的名稱要和實(shí)體類一致。

        JSONArray jsonArray = JSONArray.parseArray(datajson);
        for(int i=0; i<jsonArray.size(); i++) {
            JSONObject object = jsonArray.getJSONObject(i);
            SmartProejctEquipmentMap myclass = JSONObject.parseObject(object.toJSONString() , SmartProejctEquipmentMap.class);// 將string類型直接封裝成對象
            System.out.println(myclass.toString());
        }
