Should we implement Serializable interface while making Domain Class in hibernate

I am new in hibernate.I tried some basic CRUD operations using hibernate API.

I created a class Person

@Entity
class Person
{
   String name
}

I was able to save this class in Database. Till now I was thinking that JPA internally makes this class implement Serializable because only serialization can save the state of an object.But I tried this :

Person p=new Person();
boolean bool=p instanceof Serializable;    
sop(bool);   //false

Then I created another class Human (found this way of implementation on Hibernate doc)

@Entity
class Human implements Serializable
{
    String name    
}

Human h=new Human();
boolean bool=h instanceof Serializable    
sop(bool);  //true

Which way we should create our domain classes and how hibernate internally treats these two ways ?

Please help.

If your entities are going to be transfered over a network, to be stored in an HTTP session, or even to be stored in a file on your hard disk then they must implement Serializable. Otherwise Hibernate has nothing to do with Serialization, check more here
