Introduction In this article, we are going to see what is the best way to use the Spring Data JPA Specification when combining multiple predicates with the result set ordering logic. While you can also use query methods or the @Query annotation to define your Spring Data queries, the Spring Data JPA Specification allows you to compose dynamically various filtering criteria, which may be very convenient when you’d, otherwise, end up with lots of query method permutations.
Introduction In this article, we are going to see how we can use the JOIN FETCH clause when fetching a child collection eagerly while also limiting the number of parent records using pagination in a Spring Data JPA application. I decided to write this article because the most common solution used in many projects turns out to be extremely inefficient.
Introduction In this article, we are going to see how Spring Data query methods are built, when you should use them, and especially when you should avoid them. I decided to write this article after answering this StackOverflow question, which depicts an 87-character-long Spring Data query method. TL;DR, Don’t write query methods that cannot even fit on the screen.
Introduction In this article, we are going to see what is the best way to use the amazing SQL NOWAIT feature that allows us to avoid blocking when acquiring a row-level lock. Since all the top major database support this functionality, Hibernate offers a NOWAIT option that allows you to render the proper database-specific syntax associated with this feature without risking database portability.
