How clear session on commit?

[wizmerhill]

Hi,

I searched on many forums, but I don't find it.

I manage a lots of data with Spring, every 200 data I commit (with transaction). But an Out Of Memory happens, I think it's causes by first level cache which are not cleared. How can I force clear session on commit ?

Thanks.

Which OR-mapper do you use? If it is Hibernate, then have a look ak Session.evict and Session.clear.

I don't explicitly use evict or clear on the session. When transaction ended, I want a clear is call in the session and clear the first level cache.

The session is the first-level cache. And if you want to clear the session then you have to call the clear-method. At least I am not aware of a possibility to clear sessions implicitly.

I want when commit occurs then session is clear. Is it the default behavior or a property exists ?

Question : between two transactions, is first level cache clear ?

No... Not if you clear it yourself... You need to call session.clear() and/or session.evict to make that happen.
