Spring Data JPA - One to One mapping in spring boot | MySQL

This video covers One to One relationship in Spring Data JPA. Spring Data JPA uses Hibernate as the ORM framework internally. So if we will understand the One to One mapping's fundamental, We will be able to implement it on Spring Boot using Spring Data JPA and also in Hibernate alone.

This video mainly focus on
1. setting up a spring data jpa project
2. How one to one mapping works in dbms
3. finally how to implement one to one in Spring Boot
4. We will use MySQL database for demo

Sir can you please arrange your spring boot lectures in a sequence so that we can understand what we have to learn after each lecture ...

[GabrielLogan]

Very good video, very good indeed, explains things well and in detail. Just one thing, the "parent" of the relationship between the entities does not necessarily have to be the one that carries the foreign key, it can also be the other one without any problems, you will define this by adjusting it via OnDelete and OnUpdate. Example: User and Photo, User is the "parent" of Photo and even so it is common and even ideal in this case to have Photo "load" the "user_id" and not the other way around, which would be the User "loading" the "photo_id".
