Hibernate Criteria Lockmode

setLockMode is a method of Hibernate Criteria API. You can use a lock mode in the following way

Criteria criteria = session.createCriteria(Student.class);
	criteria.add(Restrictions.eq("name", "Ramesh"));
	criteria.setLockMode("this", LockMode.UPGRADE);
	List list = criteria.list();

An example of lockmode is given below

CriteriaLockMode.java

package net.roseindia.main;

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

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

import org.hibernate.Criteria;
import org.hibernate.LockMode;
import org.hibernate.Session;
import org.hibernate.criterion.Restrictions;

public class CriteriaLockMode {
	public static void main(String[] args) {
		Session session = HibernateUtil.getSessionFactory().openSession();
		Criteria criteria = session.createCriteria(Student.class);
		criteria.add(Restrictions.eq("name", "Ramesh"));
		criteria.setLockMode("this", LockMode.UPGRADE);
		List list = criteria.list();
		Iterator iterator = list.iterator();
		while (iterator.hasNext()) {
			Student student = (Student) iterator.next();
			System.out.println(student.getCourse());
		}
	}
}
