我正在尝试构建一个聊天应用程序。我有一个将数据从客户端发送到服务器的代码。当一个或多个客户端登录时(当客户端程序运行一次或多次时)。服务器将不接受除第一次连接之外的其余连接。请帮我解决这是我的代码:
public class Server
{
//Creating non blocking socket
public void non_Socket() throws Exception {
ServerSocketChannel ssChannel = ServerSocketChannel.open();
int port = 80;
int i=0;
ssChannel.socket().bind(new InetSocketAddress(port));
ssChannel.configureBlocking(false);
while(true)
{
SocketChannel sc = ssChannel.accept();`
if (sc == null)
{
System.out.println("Socket channel is null");
Thread.sleep(5000);
}
else
{
System.out.println("Socket channel is not null");
System.out.println("Received an incoming connection from " +
sc.socket().getRemoteSocketAddress());
new PrintRequest(sc,i).start();
i++;
}
}
}
public static void main(String [] abc) throws Exception
{
new Server().non_Socket();
}
}
class PrintRequest extends Thread {
public PrintRequest(SocketChannel sc,int i) throws Exception
{
WritableByteChannel wbc = Channels.newChannel(System.out);
ByteBuffer b = ByteBuffer.allocateDirect(1024); // read 1024 bytes
int numBytesRead = sc.read(b);
while (numBytesRead != -1)
{
b.flip();
while (b.hasRemaining())
{
wbc.write(b);
System.out.println();
//System.out.println("Stream "+i);
// System.out.println(" KKK "+b.toString());
}
//b.clear();
}
}
}
客户端代码:
public class Client extends Thread {
public void non_Client_Socket() throws Exception
{
SocketChannel sChannel = SocketChannel.open();
sChannel.configureBlocking(false);
sChannel.connect(new InetSocketAddress("localhost", 80));
while (!sChannel.finishConnect())
{
System.out.println("Channel is not connected yet");
}
System.out.println("Channel is ready to use");
/* ---------- going to send data to server ------------*/
System.out.println("please enter the text");
BufferedReader stdin=new BufferedReader(new InputStreamReader(System.in));
while(true)
{
System.out.println("Enter the text");
String HELLO_REQUEST =stdin.readLine().toString();
if(HELLO_REQUEST.equalsIgnoreCase("end"))
{
break;
}
System.out.println("Sending a request to HelloServer");
ByteBuffer buffer = ByteBuffer.wrap(HELLO_REQUEST.getBytes());
sChannel.write(buffer);
}
}
/* ---------- the data is written to sChannel server
will read from this channel ------------ */
public static void main(String [] args) throws Exception
{
new Client().non_Client_Socket();
}
}
