The best way to fetch associations with JPA and Hibernate
In this video, I'm showing you what is the best way to fetch entity associations when using JPA and Hibernate.
First, I will explain how the FetchType.EAGER and FetchType.LAZY strategies work when using JPA and Hibernate.
Afterward, you will learn how you can fetch multiple associations, no matter if those are @ManyToOne, @OneToOne, or collections.
Next, I will discuss about the N+1 query issue and see what's the best way to prevent it.
In the end, I will cover the LazyInitializationException topic and see why we should avoid the Open Session in View anti-pattern.
