Java序列化的简单例子

首先来看看要序列化的对象 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; } } 再来看看测试代码： 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("陈建泉"); 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 { //执行序列化 ObjectOutputStream out=new ObjectOutputStream(new FileOutputStream(f));out.writeObject(s); out.close(); s=null;//执行反序列化 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(); } } } 程序输出如下： 03058661 陈建泉 ************ Hangzhou,Zhejiang 从结果中可以看出，对象被正确的序列化到Serializable.dll文件中，并且可以被反序列化，这是一个简单的序列化例子。
