有木有大神知道java监听文件夹变化的方法

Question

有木有大神知道有什么效率比较高的文件监听的方法吗？我目前用的是org.apache.commons.io.monitor.FileAlterationListener，但是会有些文件会被漏掉

 DirectoryWatchService watchService = new SimpleDirectoryWatchService(); // May throw
watchService.register( // May throw
        new DirectoryWatchService.OnFileChangeListener() {
            @Override
            public void onFileCreate(String filePath) {
                // File created
            }

            @Override
            public void onFileModify(String filePath) {
                // File modified
            }

            @Override
            public void onFileDelete(String filePath) {
                // File deleted
            }
        },
        <directory>, // Directory to watch
        <file-glob-pattern-1>, // E.g. "*.log"
        <file-glob-pattern-2>, // E.g. "input-?.txt"
        ... // As many patterns as you like
);

watchService.start();
