Java序列化簡單例子

 首先來看看要序列化的對象

  Person.java

  package com.zjut.yunfeiyang;

  import java.io.Serializable;

  public class Person implements Serializable{

  private static final long serialVersionUID = -5434734211562785652L;

  public Person() {

  }

  private String name;

  private String password;

  private String id;

  private String address;

  /**

  * @return the name

  */

  public String getName() {

  return name;

  }

  /**

  * @param name the name to set

  */

  public void setName(String name) {

  this.name = name;

  }

  /**

  * @return the password

  */

  public String getPassword() {

  return password;

  }

  /**

  * @param password the password to set

  */

  public void setPassword(String password) {

  this.password = password;

  }

  /**

  * @return the id

  */

  public String getId() {

  return id;

  }

  /**

  * @param id the id to set

  */

  public void setId(String id) {

  this.id = id;

  }

  /**

  * @param address the address to set

  */

  public void setAddress(String address) {

  this.address = address;

  }

  /**

  * @return the address

  */

  public String getAddress() {

  return address;

  }

  }

  再來看看測試代碼:

  Test.java

  package com.zjut.yunfeiyang;

  import java.io.File;

  import java.io.FileInputStream;

  import java.io.FileNotFoundException;

  import java.io.FileOutputStream;

  import java.io.IOException;

  import java.io.ObjectInputStream;

  import java.io.ObjectOutputStream;

  public class Test {

  public Test() {

  }

  /**

  * @param args

  */

 public static void main(String[] args) {

  Person s=new Person();

  s.setId("03058661");

  s.setName("陳建泉");

  s.setPassword("************");

  s.setAddress("Hangzhou,Zhejiang");

  File f=new File("Serializable.dll");

  if(!f.exists())

  {

  try {

  f.createNewFile();

  } catch (IOException e) {

  // TODO Auto-generated catch block

  e.printStackTrace();

  }

  }

 try {

  //執行序列化

  ObjectOutputStream out=new ObjectOutputStream(new FileOutputStream(f));

  out.writeObject(s);

  out.close();

  s=null;

  //執行反序列化

  ObjectInputStream in=new ObjectInputStream(new FileInputStream(f));

  Person p=(Person)in.readObject();

  System.out.println(p.getId());

  System.out.println(p.getName());

  System.out.println(p.getPassword());

  System.out.println(p.getAddress());

  in.close();

  } catch (FileNotFoundException e) {

  // TODO Auto-generated catch block

  e.printStackTrace();

  } catch (IOException e) {

  // TODO Auto-generated catch block

  e.printStackTrace();

  } catch (ClassNotFoundException e) {

  // TODO Auto-generated catch block

  e.printStackTrace();

  }

  }

  }

  程序輸出如下:

  03058661

  陳建泉

  ************

  Hangzhou,Zhejiang

  從結果中可以看出,對象被正確的序列化到Serializable.dll文件中,並且可以被反序列化,這是一個簡單的序列化例子。
