Updated Spring 3.1 project to hibernate4 now getting No Session found for current thread
Question
I had to update my Spring WebFlow project to Spring 3.1 and Hibernate 4 do to trying to get maven to work. It looks like everything is working now but at the part of the project going to do a database read I get the following error:
org.hibernate.HibernateException: No Session found for current thread org.springframework.orm.hibernate4.SpringSessionContext.currentSession(SpringSessionContext.java:97)
I dont know why I did not get this error in hibernate3 but can someone please tell me how to fix this.
Here is my pom.xml

尝试将其添加到您的服务中：
@Transactional(readOnly=true, propagation=Propagation.REQUIRED)

Looks like a lazy loading issue. Did you enable either the OpenSessionFactoryInViewFilter or OpenSessionFactoryInViewInterceptor? Any code executing within a transaction should not get this exception, but rendering the view typically happens outside of a transaction necessitating the filter/interceptor. Hard to say without seeing the code.

public Session currentSession() throws HibernateException {
Object value = TransactionSynchronizationManager.getResource(this.sessionFactory);
if (value instanceof Session) {
return (Session) value;
}
else if (value instanceof SessionHolder) {
SessionHolder sessionHolder = (SessionHolder) value;
Session session = sessionHolder.getSession();
if (TransactionSynchronizationManager.isSynchronizationActive() &&
!sessionHolder.isSynchronizedWithTransaction()) {
TransactionSynchronizationManager.registerSynchronization(
new SpringSessionSynchronization(sessionHolder, this.sessionFactory));
sessionHolder.setSynchronizedWithTransaction(true);
// Switch to FlushMode.AUTO, as we have to assume a thread-bound Session
// with FlushMode.MANUAL, which needs to allow flushing within the transaction.
FlushMode flushMode = session.getFlushMode();
if (FlushMode.isManualFlushMode(flushMode) &&
!TransactionSynchronizationManager.isCurrentTransactionReadOnly()) {
session.setFlushMode(FlushMode.AUTO);
sessionHolder.setPreviousFlushMode(flushMode);
}
}
return session;
}
else if (this.jtaSessionContext != null) {
Session session = this.jtaSessionContext.currentSession();
if (TransactionSynchronizationManager.isSynchronizationActive()) {
TransactionSynchronizationManager.registerSynchronization(new SpringFlushSynchronization(session));
}
return session;
}
else {
throw new HibernateException("No Session found for current thread");
}
}
this is the exception thrown from the SpringSessionContext.java, you could debug this code to check wat had happened to the varible value, before we encounter this problem, because we use the hibernate3.SessionHolder then it can not be identified from the instanceof, hope this could be helpful.
