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?
To be complete I also insert my pom.xml containing my dependencies list:
