我想锁定特定文件夹，并且我有代码，但发现“java.io.FileNotFoundException：（访问被拒绝）”错误
public class Folder_Lock {
public static void main(String[] args) {
FileLock lock = null;
FileChannel channel = null;
try {
// Get a file channel for the file
File file = new File("C:\\Users\\kaizen\\Desktop\\mani1");
channel = new RandomAccessFile(file, "rw").getChannel();
// Use the file channel to create a lock on the file.
// This method blocks until it can retrieve the lock.
lock = channel.lock();
// Try acquiring the lock without blocking. This method returns
// null or throws an exception if the file is already locked.
try {
lock = channel.tryLock();
} catch (OverlappingFileLockException e) {
// File is already locked in this thread or virtual machine
}
// Release the lock
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (lock!=null) try { lock.release(); } catch (IOException e) { }
// Close the file
if (channel!=null) try { channel.close(); } catch (IOException e) { }
}
}
}
任何人都可以解决这个问题
