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
