Hibernate session.get() :

The get() method returns real persistent object of the mentioned class with specified identifier.

Object get(Class Clazz,Serializable id)
Clazz- persistent class
id -identifier
Returns-a persistent object or null

Example :

package net.roseindia.main;

import net.roseindia.table.Student;
import net.roseindia.util.HibernateUtil;
import org.hibernate.HibernateException;
import org.hibernate.Session;

public class HibernateSessionLoad {
public static void main(String args[]) {
Session session = HibernateUtil.getSessionFactory().openSession();
int roll = 6;

try {
Student student = (Student) session.get(Student.class, roll);
//student record of roll=6)

System.out.println("RollNo. :" + student.getRoll());
System.out.println("Name :" + student.getName());
System.out.println("Course :" + student.getCourse());
} catch (HibernateException e) {

Output :

Hibernate: select student0_.roll_no as roll1_0_0_, student0_.course as course0_0_, as name0_0_ from student student0_ where student0_.roll_no=?
