If you define the User class into the hibernate.cfg.xml class, why do you need the @Entity annotation ?
@MarcoCodes Жыл бұрын
It's a good question. I.e. you could probably leave out @Entity specifying the class directly in hibernate.cfg.xml - however, in most real life applications you'll have some sort of package scan/component scan, and then you definitely need @Entity to make it work - as opposed to specifying every class manually. Give it a try and see what Hibernate does!
@williamtlittle4 ай бұрын
My java ee application uses an EntityManager throughout, so when I am writing unit tests I need to create an EntityManager configured to use a test database to give to my application code. I created a hibernate.cfg.xml file in src/test/resources. I have a problem though that my entities are not being scanned correctly. In the config file there is a packagesToScan property which lists the package where entities are in my application. However, those packages are in src/main/java, while my tests are in src/test/java. This is causing the problem that when I create a query with the name of my entity, I get an exception which says my entity is not mapped. How do I tell hibernate to scan a package in a different directory?

19:30 - Generated Sources User_ They are not recognized by IntelliJ out of the box. I need to right tap at "target/generated-sources" node and select "Mark Directory as ..." / "Generated Sources Root" to be able to have an Import Option with the User_ class. But somehow this feels cheating if i have to setup something in the IDE after git checkout. I think this should be somehow in some settings files. i found some "howto" with a Gradle file. but this project is not using Gradle. How is the right way to setup the generated sources?

Have a look at the pom.xml file from the sample project. There's a "build-helper-maven-plugin" specified, which does add the sources automatically to your IntelliJ.

So what will happen if you create an entity class and you forget the empty constructor ? Btw if we assume that you have a constructor with all parameters why hibernate cant manage to create an object and to save it successfully
@MarcoCodes Жыл бұрын
If I remember correctly, if you're missing the (implicit or explicit) no-arg constructor, you'll simply get an exception thrown, but you'll need to try it out :) As for your second question, I suppose there are a multitude of reasons, i.e. that afaik the reflections API doesn't easily work with constructors, that having super-long constructors for classes/tables with tons of fields is akward etc etc, but don't take it as the final say :D

My googling tells me that JPA is a specification and that Hibernate is an implementation for that specification. That being said, I'm worried that I'll be confused if I read through the Java Persistence with Hibernate book when I go to work with JPA in for example Spring Boot. Is there no JPA specific book you could recommend?
@MarcoCodes Жыл бұрын
No need to worry: 99% (oversimplified) of the time when you use JPA in a Spring Boot application, it's with Hibernate as the "persistence provider". And the book gives you a perfect foundation for both, the JPA spec + Hibernate - there is no such thing as "just a JPA book", because as you said, it's just a specification.

@@MarcoCodes Thank you for the quick reply. One thing I’d like to highlight is that the same author/authors are releasing a new book called “Java Persistence with Spring Data and Hibernate” listed on Amazon with a release date on the 14th of February 2023. I wonder if that will act as an upgrade/replacement for the book recommended in this video. I’m thinking of simply waiting for this new book. Any thoughts? My current situation is I’m doing a two year Java degree. I’m in my second year and I’m starting a Volvo internship in february where they use Java/Spring Boot.
@MarcoCodes Жыл бұрын
Two things: Working through the book will realistically take you months, so it's basically always better to have started yesterday :) Plus, Spring Data comes,essentially, on top of Hibernate/JPA and everything that is in the second edition will still be valid. I.e. I would start working through the book now, and then additionally do the Spring Data once it's released, as sort of a refresher + expansion of knowledge :)
