Hello all
I'm working with hibernate3.jar + spring
I had a transactionfilter to start and terminate a hibernate session.
Code:
public class HibernateFilter implements Filter {
public void destroy() {
// TODO Auto-generated method stub
}
public void doFilter(ServletRequest request, ServletResponse response,FilterChain chain) throws IOException, ServletException {
//Start a connection to the database
HibernateUtil.currentSession();
//perform the normal http request response flow
chain.doFilter(request, response);
//close the connection to the database
HibernateUtil.closeSession();
}
public void init(FilterConfig filterConfig) throws ServletException {
// TODO Auto-generated method stub
}
}
Besides that i got an Aspect
(try)
1) starts a transaction.
2) proceeds the pointcut code
3) commits the transaction or
(catch)
4) rollback the transaction.
That aspect is pointcutted on all my service methodes that ask for :
save/delete/... to my daoobject
or
Does a specific thing for that service (like generating pdf's on a server)
Now I got this failure when i try to do a transaction in a transaction in a transaction.
Example :
open session
open transaction
pointcut code ->
in that code ->
open session
open transaction
pointcut code ->
in that code ->
open session
open transaction
pointcut code
close transaction
close session
Fault error message
apparently he can't find his previous transaction anymore.
I tried to write something to keep track of my transaction, but it doesn't work.
Code:
public class HibernateUtil {
private static Logger _logger = Logger.getLogger(HibernateUtil.class);
private static final SessionFactory sessionFactory;
/**
* Init the session factory for this class on first method call
*/
static {
try {
// Create the SessionFactory
sessionFactory = new Configuration().configure()
.buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
_logger.error("Initial SessionFactory creation failed " + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static final ThreadLocal threadLocalSession = new ThreadLocal();
public static final ThreadLocal threadLocalTransaction = new ThreadLocal();
/**
*
* <p>
* Stupid init method, nothing special. This method is called from the
* hibernate plugin for starting the factory on application server startup.
* </p>
*
*/
public static void init() {
// just emtpy to init the static method
}
/**
*
* <p>
* Retrieve the Hibernate Session from the current Thread or init it from
* the SessionFactory and save it in the current thread
* </p>
*
* @return
*/
public static Session currentSession() {
Session s = (Session) threadLocalSession.get();
// Open a new Session, if this Thread has none yet
if (s == null) {
s = sessionFactory.openSession();
threadLocalSession.set(s);
}
return s;
}
public static Transaction currentTransaction(Session session) {
Transaction t = null;
t = session.getTransaction();
if (t == null) {
t = session.beginTransaction();
threadLocalTransaction.set(t);
}
return t;
}
/**
*
* <p>
* close the current session that is in the Thread
* </p>
*
*/
public static void closeSession() {
Session s = (Session) threadLocalSession.get();
if (s != null)
s.close();
threadLocalSession.set(null);
}
}
Is there a possibility to track or save transaction or an other solution to this?
