Here is an example -

package net.roseindia.main;

import java.util.*;
import net.roseindia.table.Employee;
import net.roseindia.util.HibernateUtil;

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

public class CriteriaById{
    public static void main(String []args){
        SessionFactory sessionFactory=HibernateUtil.getSessionFactory();
        Session session=sessionFactory.openSession();
        Criteria criteria=session.createCriteria(Employee.class).add(Restrictions.eq("id", 1));

        List<Employee> employeeList = new ArrayList<Employee>();
        employeeList = criteria.list();
        Iterator it = employeeList.iterator();

        while (it.hasNext()) {
            Employee employee = (Employee) it.next();
            System.out.println(employee.getId());
            System.out.println(employee.getName());
            System.out.println(employee.getSalary());
            System.out.println(employee.getDateOfJoin());
        }
        session.close();
}
}

Output:

Hibernate: select this_.emp_id as emp1_0_0_, this_.date_of_join as date2_0_0_, this_.name as name0_0_, this_.salary as salary0_0_ from employee this_ where this_.emp_id=?

Description: You can use restrictions in criteria to display record under any condition.Here we added condition on id as -

criteria=session.createCriteria(Employee.class).add(Restrictions.eq("id", 1));
