| Video Discription | The LazyInitializationException is one of the most common exceptions when working with Hibernate. There are a few easy ways to fix it. But unfortunately, you can also find lots of bad advice online. The proclaimed fixes often replace the exception with a hidden problem that will cause trouble in production. Some of them introduce performance issues, and others might create inconsistent results. Hibernate throws the LazyInitializationException when it needs to initialize a lazily fetched association to another entity without an active session context. That’s usually the case if you try to use an uninitialized association in your client application or web layer. In this video, I will explain to you what the LazyInitializationException is, which advice you should ignore, and how to fix the exception instead. But before we proceed, if you are new here and want to learn how to build incredible efficient persistence layers with JPA and Hibernate and all types of other Java persistence related stuff, start now by subscribing and clicking the bell, so you don't miss anything.
