在分布式應用中，對象只有經過序列化才能在各個分布式組件之間傳輸，這就涉及到兩個方面的技術-發送者將對象序列化，接受者將對象反序列化，下面就是一個很好的例子！

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()); } } |

5.總結
序列化和反序列化還有其他的框架可以完成，比如Hession，有機會再研究！
