使用HibernateTemplate的问题：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.
