使用WatcherMonitor监控某个目录下文件的创建

WatcherMonitorExample.java

    public static void main(String[] args) {
        WatchMonitor watchMonitor = WatchMonitor.create("/Users/duqi/", WatchMonitor.ENTRY_CREATE, WatchMonitor.ENTRY_DELETE);
        watchMonitor.setWatcher(new Watcher() {
            @Override
            public void onCreate(WatchEvent<?> event, Path currentPath) {
                System.out.println("create1 current time:" + System.currentTimeMillis());
                System.out.println("文件创建：" + currentPath);
                System.out.println("create2 current time:" + System.currentTimeMillis());
            }

            @Override
            public void onModify(WatchEvent<?> event, Path currentPath) {
                System.out.println("文件修改：" + currentPath);
            }

            @Override
            public void onDelete(WatchEvent<?> event, Path currentPath) {
                System.out.println("文件删除：" + currentPath);
            }

            @Override
            public void onOverflow(WatchEvent<?> event, Path currentPath) {
                System.out.println("文件移除：" + currentPath);
            }
        });
        watchMonitor.start();

        System.out.println("copy1 current time:" + System.currentTimeMillis());
        FileUtil.copy("/Users/duqi/Downloads/hprof/b.hprof", "/Users/duqi/b.hprfo", true);
        System.out.println("copy2 current time:" + System.currentTimeMillis());
        try {
            Thread.sleep(100000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

文件拷贝结束后，才会创建新文件，才会引发文件创建事件
