Java Socket Demo

服务端：

package com.sux.demo;

import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.List;

public class TestServerSocket {
    public static void main(String[] args) throws IOException, ClassNotFoundException, InterruptedException {
        ReceiveThread receiveThread = new ReceiveThread();
        receiveThread.start();
    }

}

class ReceiveThread extends Thread {

    public void run() {
        try {
            ServerSocket serverSocket = new ServerSocket(8888);
            while (true) {
                Socket socket = serverSocket.accept();
                receive(socket);
                socket.close();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public void receive(Socket socket) throws IOException, ClassNotFoundException, InterruptedException {
        InputStream inputStream = socket.getInputStream();
        DataInputStream dataInputStream = new DataInputStream(inputStream);
        BufferedInputStream bufferedInputStream = new BufferedInputStream(dataInputStream);
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

        int len;
        byte[] bytes = new byte[10240];
        while ((len = bufferedInputStream.read(bytes)) > 0) {
            byteArrayOutputStream.write(bytes, 0, len);
        }

        System.out.println("Server端接收的数据：");
        List<MyInfo> list = (List<MyInfo>) SerializeUtil.Deserialize(byteArrayOutputStream.toByteArray());
        for (MyInfo myInfo : list) {
            System.out.println(myInfo.toString());
        }
    }
}

客户端：

package com.sux.demo;

import java.io.*;
import java.net.Socket;
import java.util.ArrayList;
import java.util.List;

public class TestSocket {
    public static void main(String[] args) throws IOException, ClassNotFoundException, InterruptedException {

}

class SendThread extends Thread {

        try {
            Socket socket = new Socket("127.0.0.1", 8888);
            send(socket);
            socket.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private void send(Socket socket) throws IOException, InterruptedException, ClassNotFoundException {
        List<MyInfo> list = new ArrayList<MyInfo>();
        for (int i = 0; i < 5; i++) {
            MyInfo myInfo = new MyInfo();
            myInfo.setName("数据" + i);
            myInfo.setCode(i);
            list.add(myInfo);
        }

        SocketUtil.Send(socket, list);
        System.out.println("数据已发送");
    }
}

class SocketUtil {

    public static synchronized void Send(Socket socket, Object data) throws IOException, ClassNotFoundException, InterruptedException {
        OutputStream outputStream = socket.getOutputStream();
        DataOutputStream dataOutputStream = new DataOutputStream(outputStream);
        BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(dataOutputStream);

        byte[] bytes = SerializeUtil.Serialize(data);

        bufferedOutputStream.write(bytes);
        bufferedOutputStream.flush();
    }
}

Java序列化反序列化工具类：

package com.sux.demo;

import java.io.*;

public class SerializeUtil {
    public static byte[] Serialize(Object object) throws IOException {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        ObjectOutputStream objectOutputStream = new ObjectOutputStream(byteArrayOutputStream);
        objectOutputStream.writeObject(object);
        return byteArrayOutputStream.toByteArray();
    }

    public static Object Deserialize(byte[] bytes) throws IOException, ClassNotFoundException {
        ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes);
        ObjectInputStream objectInputStream = new ObjectInputStream(byteArrayInputStream);
        return objectInputStream.readObject();
    }
