I am using Spring 3 together with Hibernate. I have a user request that starts a java thread in the spring controller and then a response is sent, so the thread might continue to work while the user http response has already been sent.
If I am working with lazy collections in my thread I get the following error:
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: my.model.MyClass.lazyCollection, no session or session was closed
I read I could use Hibernate.initialize(entity) to fully fetch the lazy collections but I cannot use this as I am filling the collection just in the thread. Furthermore I tried to use merge() but that still does not solve the problem.
Is there a way to开发者_StackOverflow manually keep the session open or to open a new one for the thread?
Thanks for your help!
You can use Spring to inject the SessionFactory
into your Runnable
, open a Session
from it, and manage the lifetime of the Session
and Transaction
using vanilla Hibernate APIs without relying on the session management magic of Spring.
