public class Test {

	/**

	 */
	public static void main(String[] args) {

			WatchKey watchKey = watchDirPath.register(watchService,StandardWatchEventKinds.ENTRY_CREATE,StandardWatchEventKinds.ENTRY_MODIFY);
			try {

					watchKey=watchService.take();
					System.out.println("==========");
						for (WatchEvent event : watchKey.pollEvents()) {
							System.out.println("An event was found after file creation of kind" + event.kind()+". The event occurred on file" + event.context());

					watchKey.reset();

}

这个伤不起啊！！！不用了！

监测本地可用，但是监测碗盘不好用，

本来第一进入监视的话，first应该是空的，本地监控first是null，而监控贡献文件时会first不是null，还弄不明白它是在那初始化的！
