我已经编写了通过套接字传输文件的代码，文件传输正确，但即使在调用.close()方法后也没有关闭。
但是文件在关闭“套接字”后关闭，但我想保持连接打开。
这里服务器将文件发送给客户端
服务器代码
public void sendFile(String sfileName) throws IOException{
try{
in = new FileInputStream(sfileName);
out = socket.getOutputStream();
transferData(in,out);
}
finally {
in.close();
in = null;
System.gc();
}
}
private void transferData(InputStream in, OutputStream out) throws IOException {
byte[] buf = new byte[8192];
int len = 0;
while(in.available()==0);
while ((len = in.read(buf)) != -1) {
out.write(buf, 0, len);
}
out.flush();
}
客户代码：
public void recieveFile(String rfileName) throws IOException{
try{
in = socket.getInputStream();
System.out.println("Reciever file : " + rfileName);
out = new FileOutputStream(rfileName);
transferData(in,out);
}
finally{
out.flush();
out.close();
out = null;
System.gc();
}
}
private void transferData(InputStream in, OutputStream out) throws IOException {
byte[] buf = new byte[8192];
int len = 0;
while(in.available()==0);
while ((len = in.read(buf)) != -1) {
out.write(buf, 0, len);
}
out.flush();
}
代码有什么问题？
