Hi Spring fans! In this installment we look at the Java Persistence API and its most ubiquitous implementation Hibernate. We look at basic Spring support for JPA, Spring Boot's auto-configuration and supported configuration properties, mapped superclasses, auditing (using Spring Data's JPA auditing facility) and journaling (using the Hibernate Envers project and Spring Data Envers).

Thanks for the tip, please note that the sound quality is really bad, the amount of noise is not acceptable at all :(

Lombok @Data with entity classes will cause some interesting issues. First of all it violates JPA serialization rules (espesialy if you are using relations maped as Set), and also it may cause infinite recursion for toString() method of entity class...

Indeed if you use a Set uniqueness has to be explicitly set with and EqualsAndHashcode

@@user-ql5mw8pv7d does junior dev konw how to use Spring? Might as well build APIs from scratch. If junior dev in your team is making these mistakes, explain to them how things work. But that shouldn't be the reason not to use a library. But it makes sense about JPA violation of serialization rules that you mentioned(although I have no idea what you meant, I will take your word for it).

at 33.00 why would i need to define the native query at the entity level instead of doing so in the repository?

Good video! One small question: Where should we store data source info like username and password if not in the properties file?

In runtime, I suppose using something like console args or environment properties of target system. But we store it in application.yaml anyway but encrypted using jasypt and we store decrypt key in our runtime env.

Can't even watch this. The audio is terrible. Between the scratchy noises and the click-clack of mouse and keyboard... It's impossible to concentrate.

thanks for the examples, but I get lost in words, for me it's a lot easier to read at least a summary of points... so it would be precious to have in attachment a small document explaining the main points, and links to the javadocs of all the Spring components used.... and having a github repository to clone with the complete example...

Did you have a look at the tutorials at spring.io already?
