Java watchservice，如何找到创建文件的目录？

Path directory = Paths.get("要监视的路径");
WatchService watchService = FileSystems.getDefault().newWatchService();
directory.register(watchService, StandardWatchEventKinds.ENTRY_CREATE);

while (true) {
    WatchKey key;
    try {
        key = watchService.take();
    } catch (InterruptedException e) {
        e.printStackTrace();
        return;
    }
    
    for (WatchEvent<?> event : key.pollEvents()) {
        WatchEvent.Kind<?> kind = event.kind();
        
        // 处理创建文件事件
        if (kind == StandardWatchEventKinds.ENTRY_CREATE) {
            Path createdFile = (Path) event.context();
            Path parentDirectory = directory.resolve(createdFile).getParent();
            System.out.println("文件创建：" + parentDirectory);
        }
    }
    
    boolean valid = key.reset();
    if (!valid) {
        break;
    }
}
