I use Spring and Hibernate in a web-app,
SessionFactory is injected into a DAO bean, and then this DAO is used in a Servlet through webservicecontext.
DAO methods are transactional, inside one of the methods I use ... getCurrentSession().save(myObject);
One servlet calls this method with an object passed.
The update seems to not be flushed at once, it takes about 5 seconds to see the changes in the database. The servlet's method in which that DAO's update method is called, takes a fraction of second to complete.
After the @Transactional method of DAO is completed, flushing may NOT happen ? It does not seem to be a rule [ I already see it ].
Then the question is this: what to do to force the session to flush after every DAO method?
It may not be a good thing to do, but talking about a Service layer, some methods must end with immediate flush, and Hibernate Session behavior is not predictable.
So what to do to guarantee that my @Transactional method persists all the changes after the last line of that method code?
getCurrentSession().flush() is the only solution?
p.s. I read somewhere that @Transactional IS ASSOCIATED with a DB Transaction. Method returns, transaction must be committed.
I do not see this happens.
