JSONObject和JSONArray的排序

运行环境：java1.8

方法：

/** * 对jsonarray做比较：size不同，返回false; 排序后的String对比，不相同返回false; * @param expect * @param actual * @return */public static boolean compareJsonArray(JSONArray expect, JSONArray actual) {int expect_size = expect.size();int actual_size = actual.size();if (expect_size != actual_size) {logger.error("the two JSONArrays' size is not equal >>"+ "expect JSONArray's size  is [[" + expect.size()+ "]], but actual JSONArray's size is [[" + actual.size()+ "]]");return false;}if (!sortJsonArray(expect).toString().equals(sortJsonArray(actual).toString())) {logger.error("the two JSONArrays' value is not equal >>"+ "expect is \r\n" + expect + ", \r\nbut actual  is \r\n"+ actual);return false;}return true;}/** * JSONObject排序 *  * @param obj * @return */@SuppressWarnings("all")public static JSONObject sortJsonObject(JSONObject obj) {Map map = new TreeMap();Iterator<String> it = obj.keys();while (it.hasNext()) {String key = it.next();Object value = obj.get(key);if (value instanceof JSONObject) {// System.out.println(value + " is JSONObject");map.put(key, sortJsonObject(JSONObject.fromObject(value)));} else if (value instanceof JSONArray) {// System.out.println(value + " is JSONArray");map.put(key, sortJsonArray(JSONArray.fromObject(value)));} else {map.put(key, value);}}return JSONObject.fromObject(map);}/** * JSONArray排序 *  * @param array * @return */@SuppressWarnings("all")public static JSONArray sortJsonArray(JSONArray array) {List list = new ArrayList();int size = array.size();for (int i = 0; i < size; i++) {Object obj = array.get(i);if (obj instanceof JSONObject) {list.add(sortJsonObject(JSONObject.fromObject(obj)));} else if (obj instanceof JSONArray) {list.add(sortJsonArray(JSONArray.fromObject(obj)));} else {list.add(obj);}}list.sort((o1, o2) -> o1.toString().compareTo(o2.toString()));return JSONArray.fromObject(list);}
