一、理由

使用JNotify监测的更全面，更快速。

二、参考代码

import net.contentobjects.jnotify.JNotify;import net.contentobjects.jnotify.JNotifyException;import net.contentobjects.jnotify.JNotifyListener;public class Main implements JNotifyListener {    public static void main(String[] args) throws JNotifyException, InterruptedException {        // path to watch        String path = "/weatherdata";        System.out.println(System.getProperty("java.library.path"));        // watch mask, specify events you care about,        // or JNotify.FILE_ANY for all events.        int mask = JNotify.FILE_CREATED                | JNotify.FILE_DELETED                | JNotify.FILE_MODIFIED                | JNotify.FILE_RENAMED;        // watch subtree?        boolean watchSubtree = true;        // add actual watch        int watchID = JNotify.addWatch(path, mask, watchSubtree, new Main());        // sleep a little, the application will exit if you        // don't (watching is asynchronous), depending on your        // application, this may not be required        Thread.sleep(1000000);        // to remove watch the watch        boolean res = JNotify.removeWatch(watchID);    }    int count = 0;    @Override    public void fileCreated(int i, String s, String s1) {        System.out.println("fileCreated s=" + i + " i=" + s + " s1=" + s1);    }    @Override    public void fileDeleted(int i, String s, String s1) {        System.out.println("fileDeleted s=" + s + " i=" + i + " s1=" + s1);    }    @Override    public void fileModified(int i, String s, String s1) {        System.out.println("fileModified s=" + s + " i=" + i + " s1=" + s1);    }    @Override    public void fileRenamed(int i, String s, String s1, String s2) {        System.out.println("fileRenamed s=" + s + " i=" + i + " s1=" + s1 + " s2=" + s2 + " count:" + (++count));    }}

三、说明

如果启动时报找不到JNotify库(https://sourceforge.net/projects/jnotify/files/jnotify/jnotify-0.94/ 下载)，请复制JNotify的最新版本库到系统相应库目录下。
