Yet Another LazyInitializationException with OpenSessionInViewFilter

**csyperski** · Nov 5th, 2012, 12:44 PM

I know there have been 100s of posts regarding this issues, but none of them seems to help me. I am very new to Spring, this is my first project I am doing using it. I am attempting to do lazy loading in my application, but I am getting the infamous: 'org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role:' I am attempting to use Spring with JSF2 (Mojarra 2.1.13) but I can't seem to figure out what I am doing wrong. I am going to break my post up due to the 10,000 character limit.

Any pointers would REALLY be appreciated as I am kind of lost. So thanks in advance!

And how would you expect the OpenSessionInView filter would help... Basically it is OpenSessionDuringRequest (view is misleading here) as soon as your request is over the session is closed and t he same goes for new requests (like your ajax request) those aren't using the same session (session/transaction is thread bound, each request is handled by a different thread).

So for JSF (or Spring Web Flow) this isn't going to work.

OK, you might not like my pointer.

In my opinion, and many others, just not everyone

1) Open Session In View is an Anti-Pattern.

Here's why, you probably already knew that in that page you needed the scripts in Site.scripts, but you didn't retreive them in your use case. Instead you were ok to increase the amount of calls back and forth to the database, and tried to lazy load them. So you probably decreased your performance for that use case.

So what do you do? 1) You do NOT set the scripts property to eager fetch in your mapping.

What you do is you write your Use case logic/query to eager fetch the scripts in the query for the Site object(s).

How does that look.

In HQL that would be something like

"FROM Site s JOIN FETCH s.scripts"

That will load all the Site objects with their scripts collections fully populated.

That calls the database only once and loads all the data you need for your JSF page, nothing more, nothing less.

Good Luck
