首先添加maven依賴

1 <dependency>
2             <groupId>org.json</groupId>
3             <artifactId>org.json</artifactId>
4             <version>chargebee-1.0</version>
5 </dependency>

string轉json

1 public static JSONObject strToJson(String str) throws JSONException{
 
2         str = "{\"code\":\"0\",\"msg\":\"success\",\"data\":{\"taskStatus\":1}}";
3         JSONObject jsonObj = new JSONObject(str);
4         System.out.print(jsonObj + "\n");
5         System.out.print(jsonObj.get("code"));
6         return jsonObj;
7 }
