How to Retrieve a Records from DataBase using Hibernate(Many to One Relationship)

Example 2:

For Retrieving the records from Employee and Address tables using Many-to-One relationship

package dao;

import java.util.Iterator;

import java.util.Set;

import org.hibernate.Session;

import session.HibernateSessionFactory;

import com.mapping.Address;

import com.mapping.Employee;

public class RetrieveRecordsfrommanyTone {

       public static void main(String[] args) {

             

Session session=HibernateSessionFactory.getSession();

Address address=new Address()     session.load(address,1);

       System.out.println(address.getStreetName());

       System.out.println(address.getCityName());

       System.out.println(address.getStateName());

       System.out.println(address.getZipcode());

      

       Set set=address.getEmployees();

      

       Iterator it=set.iterator();

      

       while(it.hasNext()){

             

              Employee employee=(Employee)it.next();           System.out.println("Emp Id is :"+employee.getId());       System.out.println(employee.getFirstName());       System.out.println(employee.getLastName());

       System.out.println(employee.getSalary());

                    

       //two employee having one address

       }

                          

       }

}

Output:

 Records printed here

 

//if Exception occurs like….

or.hibernate.ObjectNotFoundExecption

session.load(address,2);

 means address id 2 is not exist in address table
