Java聊天套接字读取和发送数据

我成功开发了一个应用程序，您可以创建/连接到服务器。我有一个名为Person的类，其中有一个公共静态LinkedList。在此列表中，我存储连接到服务器的客户端。服务器/客户端类位于同一个包中。服务器和客户端类是扩展线程（它们在后台工作）

我想做的事

我想将联机客户端列表（LinkedList）发送给连接到服务器的所有客户端

我想从客户端读取数据（StyledText中的字符串），并将其写入全局主聊天区（StyledText）

（类似于mIRC程序）

我整天都在阅读和搜索，但我从来没有看到关于“Java聊天应用”的好的解释、示例或文档。我发现了AWT，Swing，但问题是我只知道SWT。此外，我还找到了TELNET教程，输入和输出流是在控制台（CMD）中读取和写入的。我需要使用InputStreamReader、BufferedStreamReader和PrintWriter吗？如果有，是否需要将这些数据转换为字节数组，然后将它们转换为对象

为了更好地理解，我发布了一些截图：

以下是我创建服务器的方式：

DialogServer dialog = new DialogServer(new Shell());
dialog.create();
if(dialog.open() == Window.OK){
   new Server(serverAddress).start(); //dialog sets serverAddress as a String IP
}

   DialogConnect dialog = new DialogConnect(new Shell());
   dialog.create();
   if(dialog.open() == Window.OK){
      new Client(connectAddress, connectNickname).start(); // dialog sets String parameters. new Client start a new Thread for a client.
   }

服务器类：

public class Server extends Thread{

    private static ServerSocket serverSocket;
    private static Socket socket;
    private static String address;

    public Server(String address){
        this.address = address;
    }

    public void run(){
        try {
            serverSocket = new ServerSocket(5000, 10, InetAddress.getByName(address));
            View.serverUp = true;
            View.log("Server is up. Listening on " + address + ":5000");
            Person p = new Person(View.nickname, true, 100.0);
            Person.listPeople.add(p); //add ADMIN to static LinkedList
            while(true){
                socket = serverSocket.accept();
                new Client(socket).start(); // client class thread
                refresOnlineList(); // refresh UI table
            }

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

    public static void refresOnlineList(){
        View.display.syncExec(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                View.tableViewer.refresh();
                // TableViewer which contains online client list
            }
        });
    }
}

public class Client extends Thread{
    private static Socket socket;
    private static String nickname;

    public Client(Socket socket){
        this.socket = socket;
    }

    public Client(String address, String nickname){
        socket = new Socket();
        try {
            socket.connect(new InetSocketAddress(address, 5000), 10);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            View.log("Cannot connect to server.");
        }

        this.nickname = nickname;
    }

    public void run(){
        try {
            Person p = new Person(nickname, false, 15.4);
            Person.listPeople.add(p); // add PERSON to static LinkedList
            socket.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

要连接到服务器的对话框：

DialogServer dialog = new DialogServer(new Shell());
dialog.create();
if(dialog.open() == Window.OK){
   new Server(serverAddress).start(); //dialog sets serverAddress as a String IP
}

   DialogConnect dialog = new DialogConnect(new Shell());
   dialog.create();
   if(dialog.open() == Window.OK){
      new Client(connectAddress, connectNickname).start(); // dialog sets String parameters. new Client start a new Thread for a client.
   }

客户端类：

public class Server extends Thread{

    private static ServerSocket serverSocket;
    private static Socket socket;
    private static String address;

    public Server(String address){
        this.address = address;
    }

    public void run(){
        try {
            serverSocket = new ServerSocket(5000, 10, InetAddress.getByName(address));
            View.serverUp = true;
            View.log("Server is up. Listening on " + address + ":5000");
            Person p = new Person(View.nickname, true, 100.0);
            Person.listPeople.add(p); //add ADMIN to static LinkedList
            while(true){
                socket = serverSocket.accept();
                new Client(socket).start(); // client class thread
                refresOnlineList(); // refresh UI table
            }

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

    public static void refresOnlineList(){
        View.display.syncExec(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                View.tableViewer.refresh();
                // TableViewer which contains online client list
            }
        });
    }
}

public class Client extends Thread{
    private static Socket socket;
    private static String nickname;

    public Client(Socket socket){
        this.socket = socket;
    }

    public Client(String address, String nickname){
        socket = new Socket();
        try {
            socket.connect(new InetSocketAddress(address, 5000), 10);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            View.log("Cannot connect to server.");
        }

        this.nickname = nickname;
    }

    public void run(){
        try {
            Person p = new Person(nickname, false, 15.4);
            Person.listPeople.add(p); // add PERSON to static LinkedList
            socket.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

在Eclipse RCP 3.8中开发，您的目标可分为三个任务：

创建用户界面的步骤

处理网络通信

把这两个人绑在一起

堆栈溢出不是为了指导整个项目。 你需要陈述关于具体问题的具体问题

---

我建议您从控制台应用程序（客户端和服务器）开始，以摆脱创建UI的负担。完成后，您可以创建一些UI并将事件绑定到其中。

请发布一个特定问题。很难说出你想要什么。
