ObjectNode ArrayNode JsonNode

private static JsonNodeFactory factory = new JsonNodeFactory(false);

    ObjectNode objectNode = factory.objectNode();
    ObjectNode dataObjectNode = JsonNodeFactory.instance.objectNode();

    ArrayNode members = JsonNodeFactory.instance.arrayNode();

ArrayNode extends ContainerNode

ContainerNode extends ObjectNode

eg(调用的是云通讯,添加群组成员):

public static String addUserGroupByTm(String groupid, String userprimarykey, int Silence) {
       String result = "";
       ObjectNode objectNode = factory.objectNode();
       ObjectNode dataObjectNode = JsonNodeFactory.instance.objectNode();
       // check appKey format
       if (!JerseyUtils.match("^(?!-)[0-9a-zA-Z\\-]+#[0-9a-zA-Z]+", APPKEY)) {
           LOGGER.error("Bad format of Appkey: " + APPKEY);
           throw new BizException(ExceptionCode.MESSAGE_APPKEY_ERROR);
           // objectNode.put("message", "Bad format of Appkey");

           // return objectNode;
       }
       if (groupid == null || userprimarykey == null) {
           throw new BizException(ExceptionCode.REQUEST_PARAMS_MISS, ExceptionCode.REQUEST_PARAMS_MISS_MSG);
       }
       ArrayNode members = JsonNodeFactory.instance.arrayNode();
       members.add(objectNode.put("Member_Account", userprimarykey));
       dataObjectNode.put("GroupId", groupid);
       dataObjectNode.put("Member_Account", userprimarykey);
       dataObjectNode.put("Silence", Silence);
       dataObjectNode.put("MemberList", members);
       try {
           JerseyWebTarget webTarget = null;
           String sig = SigUtils.getSig(Long.valueOf(Constants.TM_APP_ID),

                   Constants.TM_APP_IDENTIFIER);
           Random r = new Random();
           int ran = r.nextInt();
           webTarget = EndPoints.TM_GROUP_TARGET.path("add_group_member").queryParam("usersig", sig)
                   .queryParam("identifier", Constants.TM_APP_IDENTIFIER).queryParam("sdkappid", Constants.TM_APP_ID)
                   .queryParam("random", String.valueOf(ran)).queryParam("contenttype", "json");

           ObjectNode resNode = factory.objectNode();
           resNode = JerseyUtils.sendRequestForTencent(webTarget, dataObjectNode, credential,

                   HTTPMethod.METHOD_POST, null);
           int ErrorCode = resNode.get("ErrorCode").asInt();
           JsonNode tempFlag = resNode.get("MemberList");
           int y = tempFlag.path(0).get("Result").asInt();

//tempFlag
           if (ErrorCode == 10019) {
               throw new BizException("B-123555", "被添加用户的帐号不存在！");
           } else if (y == 2) {
               throw new BizException("B-456122", "已经是群成员！");
           }else if (y == 1) {
               result = "success";
           } else {
               Thread.currentThread().sleep(300);
           }
       } catch (Exception e) {
           result = "error";
           e.printStackTrace();
       }

       return result;
   }

JsonNode有两个path方法(抽象),两个参数方法;一个用字符串取值,一个是int获取对象

Array与ArrayNode

Array是数组

ArrayNode与数组存储相同
