Hibernate Pagination

In this tutorial we will discuss concept of pagination in hibernate.

Pagination in Hibernate :

Pagination is used where you have to display large amount of result. It is tough to display all the record into a single page.
For convenient and better display hibernate provides concept of pagination. In pagination large result set is divided into a number of pages and at a time you can fetch one page.
For this, just set start position and page size. Use "order by" clause to sort result dataset.

Code :

String hql = "SELECT stud.roll, stud.name, stud.course FROM Student stud";
Query query = session.createQuery(hql);

setFirstResult(int arg0) : sets the starting point of your table record. It is contained in Query org.hibernate.Query.setFirstResult(int arg0)
It takes one int type argument.
setMaxResults():  sets the maximum result into your single page. It is defined in Query org.hibernate.Query.setFirstResult(int arg0).
It takes one int type argument.

Example : Here we are selecting record of student and displaying it by using pagination concept.

main class code :

package net.roseindia.main;

import java.util.Iterator;
import java.util.List;
import java.util.Map;

import net.roseindia.table.Student;
import net.roseindia.util.HibernateUtil;

import org.hibernate.Criteria;
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();
int start = 0;
int end = 5;
String hql = "SELECT stud.roll, stud.name, stud.course FROM Student stud order by stud.roll";
Query query = session.createQuery(hql);

List objectList = query.list();
Iterator iterator = objectList.iterator();
System.out.println("RollNo.\t Name \t Course");
while (iterator.hasNext()) {
Map map = (Map) iterator.next();
System.out.print("\t" + map.get("1"));
System.out.print("\t" + map.get("2"));

session.close(); // session is closed


Output :

Hibernate: select student0_.roll_no as col_0_0_, student0_.name as col_1_0_, student0_.course as col_2_0_ from student student0_ limit ?
RollNo.  Name    Course
