Socket编程实现多人聊天室(c语言版) socket编程花了我三四天的时间终于将这个程序给实现了！！！！所谓的多人聊天室，其实不过是客户端创建一个数据接收线程和数据发送线程，而在服务器端创建一个套接字数组，开启一个接受连接请求线程，不断接受来自客户端的连接请求，然后将建立的连接所形成的新套接字描述符存进套接字数组，并针对所存储的套接字描述符建立多个数据接收线程，对于所接收到的数据，开启一个数据转发进程，对套接字数组中的每... 阅读详情

在客户端输入好信息后，按回车就会抛出socket is closed异常。
附上源码
服务器端

public class Server {

public static ArrayList<Socket> list=new ArrayList<Socket>();
ServerSocket ss=null;

public static void main(String[] args) {
// TODO Auto-generated method stub
new Server();

}

public Server() {
try {
ss=new ServerSocket(1234);
System.out.println("服务器已启动，正在等待连接。。。");
while(true) {
try {
Socket s=ss.accept();
String shangxian=s.getInetAddress().getHostAddress()+"已上线";
System.out.println(shangxian);
list.add(s);
MyThread p=new MyThread(s);
new Thread(p).start(); //启动一个转发消息的线程
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}

class MyThread implements Runnable{

Socket s;
String msg;
BufferedReader br;
BufferedWriter bw;
public MyThread(Socket s) {
this.s=s;
}
@Override
public void run() {
try {
String shangxian=s.getInetAddress().getHostAddress()+"已上线";
for(Socket socket:Server.list) { //给每个客户端上线提醒
bw=new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
bw.write(shangxian);
bw.newLine();
bw.flush();
}
br=new BufferedReader(new InputStreamReader(s.getInputStream()));
while(true) {
msg=br.readLine();
br.close();
for(Socket socket:Server.list) { //给每个客户端转发消息
BufferedWriter bw1=new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
bw1.write(msg);
bw1.newLine();
bw1.flush();

}
}

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

}

客户端

public class Client {

public static void main(String[] args) {
new Client();
}
public Client() {
try {
Socket s=new Socket("127.0.0.1",1234);
System.out.println("服务器连接成功");
String msg;
ReceiveThread t=new ReceiveThread(s);
new Thread(t).start();
BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
Scanner sc=new Scanner(System.in);
while(true) {
msg=sc.nextLine();
bw.write(msg);
bw.newLine();
bw.flush();
}
} catch (UnknownHostException e) {
System.out.println("未知的服务器地址");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

class ReceiveThread implements Runnable{

String msg;
Socket s=null;

public ReceiveThread(Socket s) {
// TODO Auto-generated constructor stub
this.s=s;
}

public void run() {
try {
BufferedReader br=new BufferedReader(new InputStreamReader(s.getInputStream()));
while(true) {
msg=br.readLine();
if(msg!=null)
System.out.println(msg);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}
}
