Practical! Spring Data JPA
Spring Data JPA goes beyond the limitations of the past and allows you to complete development with just an interface, without implementing classes in the repository, as if by magic. It also provides all the basic CRUD functions that have been developed repeatedly. We will share practical know-how on Spring Data JPA.

Real-world news! Querydsl is about to open
Hello. This is Kim Young-han.
Finally, the last lecture of the practical series, practical! We are happy to inform you that Querydsl is scheduled to open^^
Lecture: Practice! Querydsl
Opening: Mid-January (planned)
Recently, Java backends are mainly used in combination with Spring Boot, JPA, and Spring Data JPA. However, the limitation that this combination cannot solve is the problem of complex queries and dynamic queries .
Querydsl goes beyond the limitations of the Java language and allows you to write queries as real Java code, not just text. It not only neatly solves the dynamic query problem that many developers have been struggling with, but also catches all syntax errors at compile time.
On top of Spring Boot and JPA, adding two fantastic frameworks, Spring Data JPA and Querydsl, makes development really enjoyable. The development codes that were considered simple and repetitive until now are significantly reduced. Developers can focus on developing core business logic. And thanks to Querydsl, even writing queries can be done in Java code, which is fun. In complex practices, the combination of Spring Data JPA and Querydsl is not an option, but a must .
I will share with you all the know-how I have accumulated from various practical projects on how to use Querydsl in practice. Please look forward to it^^!
For those of you who are curious about querydsl, please listen to the presentation I gave at the 2012 Korea Spring User Group. (It's a bit embarrassing because it's so brief. It hasn't been patched to Seoul dialect yet. Haha. Please keep in mind that the querydsl version is also an old version.)
