After finishing the first 3 lessons from the Hibernate series, I would just like to say that your explanations are so good, can't wait to continue with the next lessons. Thank you Laur for sharing your knowledge with us in such a great way.

[@laurspilca]

Glad to hear :)

Wow, you are the best teacher I have met, Your best sellers "Spring Start Here" and "Spring Security in Action" were also very helpful to me🔝

40:55 I understand that the GenerationType.IDENTITY creates the id for you in an incremental manner. But does the id generation depend on the datatype of the id field? In your example you demonstrated the GenerationType.IDENTITY with a primary key of "int". So the auto increment makes sense since it'll start from 1, 2, 3 etc. However, if I make my id field a type of "String", does the GenerationType.IDENTITY have a way of making the incremental generation work? Or in this scenario it's better to just use a different strategy.

Hi. Thanks for the question. That would work only if the DB you use has a way to generate strings. However, I don't think that's the case for any common technology.

some good stuff!

awesome content

[@Muescha]

nitpick: the title is wrong and it should be lesson 3 instead of lesson 2

[@laurspilca]

Thanks. I'm correcting it now.

Have you thought about creating a JPA/Hibernate book in the future?

[@laurspilca]

Hi. Maybe, why not. But there are quite a few already on this subject. What would mine bring new?

[@johnboy6799]

@@laurspilca I really like your teaching style after reading Spring Start Here. While there may be many books on JPA/Hibernate, you could provide a different perspective on things. But no big deal, you've already made 3 books that will be vital for me anyway.

[@johnboy6799]

@@laurspilca I do have a few more questions, if you don’t mind answering. What do you feel the topics that a Jr Java Developer should learn to get their first role? Do you feel like projects make a huge difference?

[@laurspilca]

@@johnboy6799 Hi. I think any Java developer should definitely learn at least the language fundamentals, SQL, Git, Spring and JPA basics. I don't think anyone will look at your projects but it's definitely good for you to exercise.

[@johnboy6799]

@@laurspilca Thank you for answering. So since people are less likely to look at projects, that’s harder for self taught individuals, I guess. Vs college
