100分求mq发送和接收文件的java代码或者实例

[zxggwan]

我把文件转换成类发出去 那边也能收到 也有字节数 可是写个程序把消息接收过来转换成文件就成了0字节到底为什么啊

这是我毕业设计中的关于文件传输用的代码，你可以参考参考
import java.io.*;
import java.net.*;
import java.util.zip.*;

public class FileServer extends Thread{
private String fileName;
private int port;
private File file;
private FileInputStream fis;
private ServerSocket ss;
private Socket client;
private OutputStream os;
private ZipOutputStream zos;
private DataOutputStream dos;
private byte[] buf;

public FileServer(String _fileName, int _port){
fileName=_fileName;
port=_port;
}

public void run(){
try{
file=new File(fileName);
fis=new FileInputStream(file);
}
catch(FileNotFoundException e1){
System.out.println("错误1:文件未找到！");
}

try{
ss=new ServerSocket(port);
client=ss.accept();
os=client.getOutputStream();
zos=new ZipOutputStream(os);
zos.setMethod(ZipOutputStream.DEFLATED);
zos.putNextEntry(new ZipEntry("zip"));
dos=new DataOutputStream(zos);
buf=new byte[2048];
int num=fis.read(buf);
while(num!=(-1)){
dos.write(buf,0,num);
dos.flush();
num=fis.read(buf);
}
fis.close();
dos.close();
}
catch(IOException e2){
System.out.println("错误2：IOException!"+e2);
}
}

/*测试用代码
public static void main(String[] args)throws Exception{
FileServer fs=new FileServer("F:\\graduation project\\思路.txt",3108);
fs.start();
}
*/
}

可以传输文件，由于还在测试，可能还有问题未找出
贴出来，大家共同讨论

顶。学习一下

楼上的你这是socket 通信，不是mq的消息通信吧！
