Socket基础的聊天代码

使用

Client： 客户端
Server： 服务端
使用API: 写入、写出流、套接字Socket
启动：先启动客户端，后服务端

Client类

public class Client implements Serializable {
   private Socket socket; // 套接字
    public Client() {
        // 实例化构造
        try {
            socket = new Socket("localhost", 8080);// TCP
        } catch (IOException e) {
            System.out.println("连接中断");
            e.printStackTrace();
        }
    }
    public void start(){
            try {
                OutputStream outputStream = socket.getOutputStream();
                // 使用输入流
                OutputStreamWriter outputStreamWriter = new OutputStreamWriter(outputStream, StandardCharsets.UTF_8);
                BufferedWriter bufferedWriter = new BufferedWriter(outputStreamWriter);
                // 启用行刷新
                PrintWriter printWriter = new PrintWriter(bufferedWriter,true);

                // 使用流
                Scanner scanner = new Scanner(System.in);
                System.out.println("请输入：exit为退出");
                while (true) {
                    String s = scanner.nextLine();
                    if ("exit".equals(s))  {
                    	printWriter.close();
                        bufferedWriter.close();
                        outputStreamWriter.close();
                        outputStream.close();
                        break;
                    }
                    printWriter.println(s);
                }

            } catch (IOException e) {
                System.out.println("信息中断");
                e.printStackTrace();
            }
    }

    public static void main(String[] args) {
        Client client = new Client();
        client.start();
    }
}

Server类

public class Server  implements Serializable {
    private ServerSocket serverSocket;
    public Server() {
        try {
            serverSocket = new ServerSocket(8080);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    public void start(){
        Socket accept = null;
        try {
            accept = serverSocket.accept();
            InputStream inputStream = accept.getInputStream();
            InputStreamReader inputStreamReader = new InputStreamReader(inputStream,"utf8");
            BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
            while (true) {
                String s = bufferedReader.readLine();
                System.out.println("接收"+s);
            }
        } catch (IOException e) {
            e.printStackTrace();
            System.out.println("连接中断");
        }
    }

    public static void main(String[] args) {
        Server server = new Server();
        server.start();
    }
}
