First post code

 
Package com. Dao; 

Import the Java. Util. List; 

The import org. Hibernate. Query; 
The import org. Hibernate. Session; 
Import org, hibernate SessionFactory; 
The import org. Hibernate. Transaction; 
The import org. Junit. Test; 

The import com. The entity. The Customer; 
The import com. Utils. HibernateUtils; 

Public class CustomerDaoImpl implements CustomerDao {

@ Override 
Public List The.findall () {
SessionFactory SessionFactory=null; 
The Session Session=null; 
The Transaction tx=null; 
Try {
SessionFactory=HibernateUtils. GetSessionFactory (); 
The session=sessionFactory. OpenSession (); 
Tx=session. BeginTransaction (); 

Query Query=session. CreateQuery (" from the Customer "); 
List List=query. The list (); 
For (c: Customer list) {
Be sad etCustName chtistina georgina rossetti.british poetess System. Out. Println (()); 
} 
Tx.com MIT (); 
return list; 
} the catch (Exception e) {
Tx. The rollback (); 
} the finally {
The session. The close (); 
SessionFactory. Close (); 
} 
return null; 
} 
} 

Said error is in the session. The close (); Out of here, but I this code and I learn hibernate before a project, there can be normal operation
