基於java.net.socket包的對象傳遞

本案例代碼使用java.net.socket和java.io包下的相關api實現了對象傳遞。

相關代碼如下：

服務端代碼  ServerSocketHomework：

package com.etc.test;

import java.io.IOException;
import java.io.InputStream;
import java.io.ObjectInputStream;
import java.net.ServerSocket;
import java.net.Socket;

import com.etc.entity.Emp;

public class ServerSocketHomework {

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

        ServerSocket serverSocket = null;
        Socket socket = null;
        InputStream is = null;
        ObjectInputStream ois = null;
        // 處於監聽狀態,等待連接
        try {
            
            serverSocket = new ServerSocket(1234);
            System.out.println("服務端正在監聽....");
            // 返回一個socket對象，這個socket對象的功能?
            socket = serverSocket.accept();

            is = socket.getInputStream();
            // 讀對象[反序列化]
            ois = new ObjectInputStream(is);

            Object obj = ois.readObject();

            if (obj instanceof Emp) {
                Emp emp = (Emp) obj;
                System.out.println("emp :" + emp);
            }
        } catch (IOException | ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            // 釋放資源
            try {
                serverSocket.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

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

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

    }

上例中使用的實體類，要自己定義，注意要實現序列化接口：
