Problems using HibernateTemplate: java.lang.NoSuchMethodError: org.hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session;

Question

I am quite new in Spring world and I am going crazy trying to integrate Hibernate in Spring application using HibernateTemplate abstract support class

I have the following class to persist on database table:

package org.andrea.myexample.HibernateOnSpring.entity;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="person")
public class Person {

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int pid;

private String firstname;

private String lastname;

public int getPid() {
    return pid;
}

public void setPid(int pid) {
    this.pid = pid;
}

public String getFirstname() {
    return firstname;
}

public void setFirstname(String firstname) {
    this.firstname = firstname;
}

public String getLastname() {
    return lastname;
}

public void setLastname(String lastname) {
    this.lastname = lastname;
}
}

Next to it I have create an interface named PersonDAO in wich I only define my CRUD method. So I have implement this interface by a class named PersonDAOImpl that also extend the Spring abstract class HibernateTemplate:

package org.andrea.myexample.HibernateOnSpring.dao;

import java.util.List;

import org.andrea.myexample.HibernateOnSpring.entity.Person;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public class PersonDAOImpl extends HibernateDaoSupport implements PersonDAO{


public void addPerson(Person p) {
    getHibernateTemplate().saveOrUpdate(p);

}

public Person getById(int id) {
    // TODO Auto-generated method stub
    return null;
}

public List<Person> getPersonsList() {
    // TODO Auto-generated method stub
    return null;
}

public void delete(int id) {
    // TODO Auto-generated method stub

}

public void update(Person person) {
    // TODO Auto-generated method stub

}   

}

(at the moment I am trying to implement only the addPerson() method)

Then I have create a main class to test the operation of insert a new object into the database table:

package org.andrea.myexample.HibernateOnSpring;

import org.andrea.myexample.HibernateOnSpring.dao.PersonDAO;
import org.andrea.myexample.HibernateOnSpring.entity.Person;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MainApp {

public static void main(String[] args) {

    ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");
    System.out.println("Contesto recuperato: " + context);

    Person persona1 = new Person();

    persona1.setFirstname("Pippo");
    persona1.setLastname("Blabla");

    System.out.println("Creato persona1: " + persona1);

    PersonDAO dao = (PersonDAO) context.getBean("personDAOImpl");

    System.out.println("Creato dao object: " + dao);

    dao.addPerson(persona1);

    System.out.println("persona1 salvata nel database");
}

}

As you can see the PersonDAOImpl class extends HibernateTemplate so I think that it have to contain the operation of setting of the sessionFactory...

The problem is that when I try to run this MainApp class I obtain the following exception:

Exception in thread "main" java.lang.NoSuchMethodError: org.hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session;
    at org.springframework.orm.hibernate3.SessionFactoryUtils.doGetSession(SessionFactoryUtils.java:323)

    at org.andrea.myexample.HibernateOnSpring.dao.PersonDAOImpl.addPerson(PersonDAOImpl.java:12)
    at org.andrea.myexample.HibernateOnSpring.MainApp.main(MainApp.java:26)

Why I have this problem? how can I solve it?

Answer 1

You should be using Springs Hibernate4 support

import org.springframework.orm.hibernate4.support.HibernateDaoSupport;

More details here: http://blog.springsource.org/2012/04/06/migrating-to-spring-3-1-and-hibernate-4-1/

Answer 2

Since HibernateTemplate is no longer supported in Hibernate 4.x and my current project is riddled with the use of HibernateTemplate I've opted to create and use my own custom HibernateTemplate.

Rather than extending HibernateDaoSupport I just added a getHibernateTemplate() method to my DAO. In my custom HibernateTemplate I then use the org.hibernate.SessionFactory to perform the same operations.
