Could n't get session in DAO(Getting Null pointer Exception)

[salientvijay]

Hi

I am trying to use Spring MVC and Hibernate in my project and have used Javax.peristence annotations to map the tables in entity classes to avoid table mapping in xml and have used all required configuration in common spring configuration xml file called "test-servlet.xml" . I am facing the problem that i could n't get session in my DAO class

import java.util.logging.Logger;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional
public class PlUserDao {
	@Resource(name = "mySessionFactory")
	private SessionFactory sessionFactory;
	protected static Logger logger = Logger.getLogger("service");
	
	 public void setSessionFactory(SessionFactory sessionFactory) {
	        this.sessionFactory = sessionFactory;
	    }

	// Stores a new guest:

	public void add(Object plUser) {
		 logger.fine("Adding new person");
		Session session = this.sessionFactory.getCurrentSession();-Null Pointer Exception Over Here
		session.save(plUser);
	}

}

the below is the configuration file

Try using @Autowired instead of @Resource.
