Issue in session factory -----Spring MVC + hibernate

[saravana]

Hi guys ,
I'm developing a project in Spring MVC + hibernate technology.
My issue is , could not autowire the sessionfactory field.
if i autowire, i'm facing an issue is that,

" org.springframework.beans.factory.NoSuchBeanDefini tionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Aut owired(required=true)} ".


Meanwhile i'm getting an java.lang.NullPointer Exception for this code
sessionFactory.getCurrentSession().save(form);

can anyone help me in this ?.






package com.epro.DAO;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autow ired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transac tional;

import com.epro.controller.FormController;
import com.epro.model.Userregistration;

@Repository
@Transactional
public class RegisterDAO {

@Autowired
private SessionFactory sessionFactory;

public String saveRegistration(Userregistration form) {
try {
System.out.println("Saving to DB");
sessionFactory.getCurrentSession().save(form);
} catch (Exception e) {
System.out.println("Exception>>>>>"+e);
e.printStackTrace();
}
return "registerForm";

}

}
