Java 序列化和反序列化实例详解

在分布式应用中，对象只有经过序列化才能在各个分布式组件之间传输，这就涉及到两个方面的技术-发送者将对象序列化，接受者将对象反序列化，下面就是一个很好的例子！

1.实体-Employee

import java.io.Serializable; public class Employee implements Serializable{ /** * */ private static final long serialVersionUID = 1L; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } private String name; private int age; }

2.SerializeHelper

import java.io.ByteArrayInputStream; import java.io.ByteArrayOutputStream; import java.io.IOException; import java.io.ObjectInputStream; import java.io.ObjectOutputStream; public class SerializeHelper { public byte[] Serialize(Object object) { ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(); try { ObjectOutputStream objectOutputStream = new ObjectOutputStream(byteArrayOutputStream); //将对象写入到字节数组中进行序列化 objectOutputStream.writeObject(object); return byteArrayOutputStream.toByteArray(); } catch (IOException e) { e.printStackTrace(); } return null; } public Object deSerialize(byte[] bytes) { //将二进制数组导入字节数据流中 ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes); try { //将字节数组流转化为对象 ObjectInputStream objectInputStream = new ObjectInputStream(byteArrayInputStream); return objectInputStream.readObject(); } catch (IOException e) { e.printStackTrace(); } catch (ClassNotFoundException e) { e.printStackTrace(); } return null; } }

3.测试类

public class Hello { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub SerializeHelper serializeHelper = new SerializeHelper(); Employee employee = new Employee(); employee.setName("admin"); employee.setAge(20); byte[] serializObject = serializeHelper.Serialize(employee); System.out.println(serializObject); Employee e = (Employee)serializeHelper.deSerialize(serializObject); System.out.println("Name: " + e.getName()+",Age: " + e.getAge()); } }

4.输出

[B@e05d173 Name: admin,Age: 20

5.总结

序列化和反序列化还有其他的框架可以完成，比如Hession，有机会再研究！
