客户端代码：
//1,创建客户端socket。
Socket s = new Socket("172.18.24.57",10006);
//2,读取客户端要上传的图片文件。
FileInputStream fis = new FileInputStream("c:\\0.bmp");
//3,获取socket输出流，将读到图片数据发送给服务端。
OutputStream out = s.getOutputStream();
byte[] buf = new byte[1024];
int len = 0;
while((len=fis.read(buf))!=-1){
out.write(buf,0,len);
}
s.shutdownOutput();
//读取服务端发回的内容。
InputStream in = s.getInputStream();
byte[] bufIn = new byte[1024];
int lenIn = in.read(buf);
String text = new String(buf,0,lenIn);
System.out.println(text);
fis.close();
s.close();
服务端代码：
ServerSocket ss = new ServerSocket(10005);
//2,
Socket s = ss.accept();
System.out.println(s.getInetAddress().getHostAddress()+".....connected");
//3,
BufferedReader bufIn = new BufferedReader(new InputStreamReader(s.getInputStream()));
//4,
BufferedWriter bufw = new BufferedWriter(new FileWriter("c:\\server.txt"));
String line = null;
while((line=bufIn.readLine())!=null){
// if("over".equals(line))
// break;
bufw.write(line);
bufw.newLine();
bufw.flush();
}
PrintWriter out = new PrintWriter(s.getOutputStream(),true);
out.println("上传成功");
bufw.close();
s.close();
ss.close();

问题描述：客户端执行 s.shutdownOutput();已经关闭了socket输出流，为什么服务端还可以向socket管道out.println("上传成功");写数据？http://ask.csdn.net/#
