基于java.net.socket包的对象传递

本案例代码使用java.net.socket和java.io包下的相关api实现了对象传递。

相关代码如下：

服务端代码  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;
        // 处于监听状态,等待连接
        try {
            
            serverSocket = new ServerSocket(1234);
            System.out.println("服务端正在监听....");
            // 返回一个socket对象，这个socket对象的功能?
            socket = serverSocket.accept();

            is = socket.getInputStream();
            // 读对象[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 {
            // 释放资源
            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();
            }
        }

    }

}

import java.io.ObjectOutputStream;
import java.io.OutputStream;
import java.net.Socket;
import java.util.Scanner;

import com.etc.entity.Emp;

public class ClientHomework {

    public static void main(String[] args) {
        Socket socket = null;
        OutputStream os = null;
        ObjectOutputStream oos = null;
        Scanner input = new Scanner(System.in);
        // 处于监听状态,等待连接
        try {
            // 换这个socket是和serversocket进行交互的对象
            socket = new Socket("127.0.0.1", 1234);
            os = socket.getOutputStream();
            // 写[序列化的过程]
            oos = new ObjectOutputStream(os);

                System.out.println("请输入员工的id,name,age,address,job,sal");
                int id = input.nextInt();
                String name = input.next();
                int age = input.nextInt();

                String job = input.next();
                double sal = input.nextDouble();

                Emp emp = new Emp(id, name, age, address, job, sal);

                oos.writeObject(emp);
                System.out.println("传输成功~");
            

                input.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            // 释放资源
            try {
                socket.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 {
                os.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

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

    }

}

上例中使用的实体类，要自己定义，注意要实现序列化接口：
