Question

假设这些：

ObjectOutputStream out =
    new ObjectOutputStream(new BufferedOutputStream(remote.getOutputStream()));
ObjectInputStream in =
    new ObjectInputStream(new BufferedInputStream(remote.getInputStream()));

发送“启动文件发送”消息和大小并成功读取另一端的字符串和长号后（您可以假设我已经处理过它们）我希望能够编写整个文件而无需实例新的OutputStream。到目前为止我所做的是：

InputStream buf = new BufferedInputStream(new FileInputStream(file));
out.writeUnshared(new PeerProtocol(PeerProtocol.Type.FILE, file.getName(), file.length()));
int sum = 0, len;
byte[] buffer = new byte[remote.getSendBufferSize()];
out.flush();
out.reset();
while ((len = buf.read(buffer)) > 0) {
    out.write(buffer, 0, len);
    sum += len;
    sendFileDialogController.updatePercentage((double) sum / file.length() * 100);
}
// System.out.println("done sending");
//out.flush(); didnt work neither
sendFileDialogController.updatePercentage(100);
buf.close();

问题是我总是丢失最后几个字节，因此文件已损坏且无法使用。如何解决这个问题？

使用ObjectOutputStream和ObjectInputStream
