推荐答案
最好的解决办法我能想到的是要做到这一点就像你在用java做://www.javabeat:在的这个链接描述如下:
The best solution I can think of is to do it like you do in java: An example in this link describes as follows:
import java.io.*;
import java.nio.channels.FileChannel;
import java.nio.channels.FileLock;
public class FileLockTest {
public static void main(String[] args) throws Exception {
RandomAccessFile file = null;
FileLock fileLock = null;
try
{
file = new RandomAccessFile("FileToBeLocked", "rw");
FileChannel fileChannel = file.getChannel();
fileLock = fileChannel.tryLock();
if (fileLock != null){
System.out.println("File is locked");
accessTheLockedFile();
}
}finally{
if (fileLock != null){
fileLock.release();
}
}
}
static void accessTheLockedFile(){
try{
FileInputStream input = new FileInputStream("FileToBeLocked");
int data = input.read();
System.out.println(data);
}catch (Exception exception){
exception.printStackTrace();
}
}
}
