socket传送自定义对象

来源：互联网发布：软件测试第二版中文版编辑：程序博客网时间：2024/06/06 01:15

继续上回的socket。上回的socket传递的是一个基本类，这回传递的是一个自定义对象，自然是object，所以用到的流，也就是objectinputstream。废话不多说，直接上代码

===================================================================================================================================

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.ObjectInputStream;
import java.io.OutputStreamWriter;
import java.net.ServerSocket;
import java.net.Socket;

import MyBean.User;

public class MySocket {
ServerSocket serverSocket=null;
int port=54543;
ObjectInputStream objectInputStream=null;
User user=null;
public MySocket() {
try {
   serverSocket=new ServerSocket(port);
   while(
           true
           ){
Socket socket=serverSocket.accept();
user=new User();
   objectInputStream=new ObjectInputStream(socket.getInputStream());
user=(User) objectInputStream.readObject();
System.out.println("收到了");
objectInputStream.close();
socket.close();
if (user==null) {
   System.out.println("空的，*");
}
System.out.println(user.getAge());
   }
} catch (Exception e) {
}
}
public static void main(String[] args) {
   new MySocket();
}
}

代码比较简单，里面的user是自己定义的。接下来是客户端的

=====================================================================================

package com.example.socketc8;

import android.support.v7.app.ActionBarActivity;

import java.io.BufferedWriter;
import java.io.ObjectOutputStream;
import java.io.OutputStreamWriter;
import java.net.Socket;

import MyBean.User;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements Runnable{
Button button;
Socket socket;
User user=null;
ObjectOutputStream objectOutputStream=null;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
   button=(Button) this.findViewById(R.id.button1);
   button.setOnClickListener(new OnClickListener() {

       @Override
       public void onClick(View v) {
           new Thread(MainActivity.this).start();
       }
   });
   }

   @Override
   public void run() {
try {
   user=new User("护士",20);
socket=new Socket("183.26.254.109",54543);
objectOutputStream=new ObjectOutputStream(socket.getOutputStream());
objectOutputStream.writeObject(user);
objectOutputStream.flush();
objectOutputStream.close();
socket.close();
}
catch (Exception e) {
   // TODO: handle exception
}
   }


}

接下来将两点注意点

1.0.在使用时，user这个类（也就是我们的自定义对象类）必须是实现序列化。也就是implements serlizable

2.0在使用时，注意c.s两端必须把user这个来放在同一个包中，如package MyBean;，至于为什么，希望大神留言说下，谢谢，直接把bean的代码也上吧

package MyBean;

import java.io.Serializable;

public class User implements Serializable{
String name;
int age;
public User(String name,int age) {
this.name=name;
this.age=age;
}
public User() {
}
public void setAge(int age) {
   this.age = age;
}
public int getAge() {
   return age;
}
public void setName(String name) {
   this.name = name;
}
public String getName() {
   return name;
}
}
然后，希望你们那边c盘可以用来操作吧
