如何在Java中获取"ShareDenyWrite“文件锁

import java.io.File;
import java.io.RandomAccessFile;
import java.nio.channels.FileChannel;
import java.nio.channels.FileLock;

public class FileLockExample {
    public static void main(String[] args) {
        try {
            // 打开文件
            File file = new File("example.txt");
            RandomAccessFile randomAccessFile = new RandomAccessFile(file, "rw");
            FileChannel channel = randomAccessFile.getChannel();

            // 获取共享读锁（ShareDenyWrite）
            FileLock lock = channel.lock(0, Long.MAX_VALUE, true);

            System.out.println("File is locked for writing by this process.");

            // 在此处执行文件操作...

            // 释放锁
            lock.release();
            System.out.println("File lock released.");

            // 关闭文件通道
            channel.close();
            randomAccessFile.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
