        System.out.println(root.get("questionnaireID").toString());//直接取的根节点值 

        JsonArray AnswerList = root.getAsJsonArray("answerResults");//取数组 

        for (int i = 0; i < AnswerList.size(); i++) { 
            System.out.println(AnswerList.get(i).getAsJsonObject().get("questionID").toString()); 
            System.out.println(AnswerList.get(i).getAsJsonObject().get("anserContent").toString());
