通過socket串連傳遞java對象（對象序列化）

這篇文章主要實現的是j：通過socket傳遞Java對象。採用的方法就是對象序列化。方法是：通過socket建立c/s串連；通過ObjectOutputStream，ObjectOutputStream 讀寫對象。唯一需要留意的是傳遞的java 對象需要實現Serializable標記介面。程式碼封裝括：java對象類，Employee; socket client類；server類。主要代碼如下：

java對象類：

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類：

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類：

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);
      }
   }

}
