关于Map转LinkedHashMap的解决办法

代码非常的简单哈，对于Map中存在的子Map，采用递归形式将各个子Map都转换

/**
	 * 将Map转换为LinkedHashMap（带key）
	 * @param dataMap
	 * @param keyName
	 * @return
	 */
	public static LinkedHashMap getMapValueForLinkedHashMap(Map dataMap, String keyName) {
		LinkedHashMap returnMap = new LinkedHashMap();
		if (MapUtil.isEmpty(dataMap)) {
			return returnMap;
		}
		Object valueObj = dataMap.get(keyName);
		if (valueObj instanceof Map) {
			Map objMap = (Map) valueObj;
			Iterator iterator = objMap.keySet().iterator();
			while (iterator.hasNext()) {
				Object objKey = iterator.next();
				Object objValue = objMap.get(objKey);
				if (objValue instanceof Map) {
					returnMap.put(objKey, getMapValueForLinkedHashMap((Map)objValue));
				} else {
					returnMap.put(objKey, objValue);
				}
			}
		}
		return returnMap;
	}

	/**
	 * 将Map转换为LinkedHashMap（不带key）
	 * @param dataMap
	 * @return
	 */
	public static LinkedHashMap getMapValueForLinkedHashMap(Map dataMap) {
		LinkedHashMap returnMap = new LinkedHashMap();
		if (MapUtil.isEmpty(dataMap)) {
			return returnMap;
		}
		Iterator iterator = dataMap.keySet().iterator();
		while (iterator.hasNext()) {
			Object objKey = iterator.next();
			Object objValue = dataMap.get(objKey);
			if (objValue instanceof Map) {
				returnMap.put(objKey, getMapValueForLinkedHashMap((Map) objValue));
			} else {
				returnMap.put(objKey, objValue);
			}
		}
		return returnMap;
