通过socket连接传递java对象（对象序列化）

这篇文章主要实现的是j：通过socket传递Java对象。采用的方法就是对象序列化。方法是：通过socket建立c/s连接；通过ObjectOutputStream，ObjectOutputStream 读写对象。唯一需要留意的是传递的java 对象需要实现Serializable标记接口。代码包括：java对象类，Employee; socket client类；server类。主要代码如下：

java对象类：

import java.io.*;
import java.util.*;

public class Employee implements Serializable {

   private int employeeNumber;
   private String employeeName;

   Employee(int num, String name) {
      employeeNumber = num;
      employeeName= name;
   }

    public int getEmployeeNumber() {
      return employeeNumber ;
   }

   public void setEmployeeNumber(int num) {
      employeeNumber = num;
   }

   public String getEmployeeName() {
      return employeeName ;
   }

   public void setEmployeeName(String name) {
      employeeName = name;
   }
}

client类：

import java.io.*;
import java.net.*;

public class Client {

   public static void main(String[] arg) {
      try {
         Employee joe = new Employee(150, "Joe");

         System.out.println("employeeNumber= "
                            + joe .getEmployeeNumber());
         System.out.println("employeeName= "
                            + joe .getEmployeeName());

         Socket socketConnection = new Socket("127.0.0.1", 11111);


         ObjectOutputStream clientOutputStream = new
            ObjectOutputStream(socketConnection.getOutputStream());
         ObjectInputStream clientInputStream = new 
            ObjectInputStream(socketConnection.getInputStream());

         clientOutputStream.writeObject(joe);

         joe= (Employee)clientInputStream.readObject();

         System.out.println("employeeNumber= "
                            + joe .getEmployeeNumber());
         System.out.println("employeeName= "
                            + joe .getEmployeeName());

         clientOutputStream.close();
         clientInputStream.close();

      } catch (Exception e) {System.out.println(e); }
   }
}

Server类：

import java.io.*;
import java.net.*;

public class Server {

   public static void main(String[] arg) {

      Employee employee = null;

      try {

         ServerSocket socketConnection = new ServerSocket(11111);

         System.out.println("Server Waiting");

         Socket pipe = socketConnection.accept();

         ObjectInputStream serverInputStream = new   
            ObjectInputStream(pipe.getInputStream());

         ObjectOutputStream serverOutputStream = new
            ObjectOutputStream(pipe.getOutputStream());

         employee = (Employee )serverInputStream.readObject();

         employee .setEmployeeNumber(256);
         employee .setEmployeeName("John");

         serverOutputStream.writeObject(employee);

         serverInputStream.close();
         serverOutputStream.close();


      }  catch(Exception e) {System.out.println(e);
      }
   }

}
