字符串到Json对象到Java中的Json数组

需要将下面的json响应转换为json对象，然后将“更新”字段转换为json数组。 基本上需要获取每个键、值对

 {
"Response": [
    {
        "TicketID": "200",
        "update": [
            {
                "Type": "Group",
                "user": "ABC",
                "groupName": "RTT",
                "updatetime": "1465367505863"
            },
            {
                "Type": "status",
                "user": "ABC",
                "status": "Open",
                "updatetime": "1465367505858"
            },
            {
                "Type": "comment",
                "user": "ABC",
                "comments": "Updating ",
                "updatetime": "1465367505854"
            }
        ]
    },
    {
        "TicketID": "300",
        "update": [
            {
                "Type": "Group",
                "user": "ABC",
                "groupName": "RTT",
                "updatetime": "1465367505863"
            },
            {
                "Type": "status",
                "user": "ABC",
                "status": "Open",
                "updatetime": "1465367505854"
            },
            {
                "Type": "comment",
                "user": "ABC",
                "comments": "Updating Group",
                "updatetime": "1465367505834"
            }
        ]
    }
]
}

我尝试了以下代码：-

                    InputStream is = new ByteArrayInputStream(ticket.getBytes());
    // create json reader from json
    JsonReader reader = Json.createReader(is);

    // get the jsonobject structure from JsonReader
    JsonObject ticObj = reader.readObject();

    JsonArray arrTicket = ticObj.getJsonArray("update");
    String tktid=ticObj.getString("TicketID");
    System.out.println("Ticket id is "+tktid);

    System.out.println("ticket Id =>");

    for (javax.json.JsonValue value : arrTicket) {
        String ticketid = value.toString();
        System.out.print(" " + ticketid + "\n");

    }

将下面的错误获取为“javax.json.stream.JsonParsingException:Unexpected char 84 at（行号=1，列号=16，偏移量=15）”

如下操作：

        JSONObject jsonObject = new JSONObject("{" +

JSONArray JSONArray=jsonObject.optJSONArray（“响应”）；

解析JSON响应并将它们添加到响应列表模型中，以后可以根据需要查询这些模型。由于响应不一致，请确保在每次解析响应时检查键，以避免崩溃

String response = "JSON Response String";

    ArrayList<ResponseModel> responseModelArrayList = new ArrayList<>();

    try {
        JSONObject rootJsonObject = new JSONObject(response);
        JSONArray responseJsonArray = new JSONArray(rootJsonObject.getString("Response"));

        for (int i = 0; i < responseJsonArray.length(); i++) {
            JSONObject childJsonObject = new JSONObject(responseJsonArray.get(i).toString());
            String str_ticketID = childJsonObject.getString("TicketID");
            JSONArray jsonArray = new JSONArray(childJsonObject.getString("update"));

            for (int j = 0; j < jsonArray.length(); j++) {
                JSONObject updateChildJsonObject = new JSONObject(jsonArray.get(j).toString());

                ResponseModel responseModel = new ResponseModel();
                responseModel.type = updateChildJsonObject.getString("Type");
                responseModel.user = updateChildJsonObject.getString("user");

                if (updateChildJsonObject.has("groupName"))
                    responseModel.groupName = updateChildJsonObject.getString("groupName");

                if (updateChildJsonObject.has("status"))
                    responseModel.status = updateChildJsonObject.getString("status");

                if (updateChildJsonObject.has("comments"))
                    responseModel.comments = updateChildJsonObject.getString("comments");

                responseModel.updateTime = updateChildJsonObject.getString("updatetime");

                responseModelArrayList.add(responseModel);
            }
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

class ResponseModel implements Serializable {
    private String type;
    private String user;
    private String groupName;
    private String status;
    private String comments;
    private String updateTime;

}

String response=“JSON响应字符串”；
ArrayList responseModelArrayList=新建ArrayList（）；
试一试{
JSONObject rootJsonObject=新JSONObject（响应）；
JSONArray responseJsonArray=新的JSONArray（rootJsonObject.getString（“Response”）；
对于（int i=0；i

update
