package roseindia.tutorial.hibernate;

import java.util.List;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

/**
* @author Deepak Kumar
*
* http://www.roseindia.net
* Hibernate example to inset data into Contact table
*/
public class FirstExample {
public static void main(String[] args) {
FirstExample fe = new FirstExample();
Session session = null;
Transaction tx = null;
List list =null;

try{
// This step will read hibernate.cfg.xml and prepare hibernate for use
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
session =sessionFactory.openSession();
tx=session.beginTransaction();

//Insert or Update
System.out.println("Insert or Update data...\n");
fe.saveOrUpdate(session, tx);
//Fetching data...
System.out.println("Fetching data...\n");
fe.getContactRecords(list,session);

System.out.println("Done");
}catch(Exception e){
System.out.println(e.getMessage());
}finally{
// Actual contact insertion will happen at this step
session.flush();
session.close();

}

}
public void saveOrUpdate(Session session,Transaction tx) {
//Create new instance of Contact and set values in it by reading them from form object
System.out.println("Inserting Record");

// TODO Auto-generated method stub
Contact contact = new Contact();
contact.setId(7);
contact.setFirstName("Deepak");
contact.setLastName("Kumar");
contact.setEmail("deepak_38@yahoo.com");
session.saveOrUpdate(contact);
tx.commit();
System.out.println("\n before update");
}
public void getContactRecords(List list,Session session){
Query query = session.createQuery("from roseindia.tutorial.hibernate.Contact");
/** execute query and get result in form of Java objects */
list = query.list();
System.out.println("intial value---> "+list.get(0));
if(list.size() >0){
int i=0;
for(;i<list.size();i++)
{
Contact c = (Contact)list.get(i);

System.out.println(c.getId());
System.out.println(c.getFirstName());
System.out.println(c.getLastName());
System.out.println(c.getEmail());

}
}
}
}

And one more important thing is we need to provide as
In hibernate.cfg.xml:

<property name="hibernate.connection.password">root</property>

After running successfully please check in DB for the row insertion.
