Posts that have been written about Hibernate’s LazyInitializationException could probably fill whole books. Yet, I believe each of them focuses on a particular aspect of it: some on a specific solution, some on how to solve it with Spring Boot, etc. I’d like this post to be the definitive guide on the subject, even though I’m pretty sure it won’t. At least, I’ll be able to point others to it.

I haven’t used Hibernate for a long time, and I haven’t blogged about it for even longer. Recently, I was working on a blog post in the context of my job on setting up an evergreen cache. When I was coding the demo, I faced some issue regarding Hibernate’s Query Cache: it didn’t work as I expected it to. Finally, after some time, I managed to fix the issue.

Despite the current trend regarding &nbps;ORM frameworks, I never had any issue using JPA nor Hibernate. I must admit that my use-cases were pretty simple. Also, since that was already some years ago, we hosted those applications on our own on-site infrastructure so that the search for the ultimate performance - and its associated savings - was not a goal; empowering junior developers who were not familiar with a lot of technologies was.

This is the 7th post in the Hibernate hard facts focus series. In this post, we’ll have a look at the difference between saveOrUpdate() and merge(). Hibernate’s way for updating entities is through the update() method. We can get an object, detach it from the session and then update it later with no problem.

This is the 6th post in the Hibernate hard facts focus series. In this article, I will show you how to use the fetch profile feature introduced in Hibernate 3.5. Lazy loading is a core feature in Hibernate: it saves memory space. The reasoning behind it is, if you don’t use an association, you don’t need the object and thus, Hibernate does not load it into memory. Hibernate fills the lazy loaded attribute with a proxy that makes the SQL request when the getter is called.

This is the 3rd post in the Hibernate hard facts focus series. In the third article of this serie, I will show how to tweak Hibernate so as to convert any database data types to and from any Java type so as to decouple your database model from your object model.

Do you remember the classic Atari ST game where you, as a fish, eat other fishes while getting bigger and avoiding bigger fishes to eat you? It seems the last 4 years has seen its share of fishes eat and being eaten.

This is the 2nd post in the Hibernate hard facts focus series. Hibernate is a widely-used Object Relational Mapping framework. Many organizations use it across their projects in order to manage their data access tier. Yet, many developers working on Hibernate don’t fully understand the full measure of its features.
