Hibernate save()
This tutorial explain how save() works in hibernate.
Hibernate save() :
The function of save() is to save content into database. It saves new record without caring of existence of ID.
session.save(Object object) : saves the instance of
persistent class into database table.
Here object is your persistent class.
session.save(String entityName, Object object) : Persist the
given transient instance, first assigning a generated identifier.
Here is two parameter one is entityName and other is Object, your persistent
class.
Example : In this example we are saving student record by using save().
package net.roseindia.main;
import net.roseindia.table.Student;
import net.roseindia.util.HibernateUtil;
import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;
public class MainClazz {
public static void main(String[] args) {
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction transaction = null;
try {transaction=session.beginTransaction();
Student student=new Student();
student.setRoll(7);
student.setName("Glinto");
student.setCourse("Hibernate");
session.save(student);
transaction.commit();
System.out.println("Record saved");
session.flush();
} catch (HibernateException e) {
transaction.rollback();
e.printStackTrace();
} finally {
session.close();
}
}
}
Output:
Hibernate: insert into student (course, name) values (?, ?) Record saved
