Spring Boot Full Course #32 Spring Data JPA removes repetitive repository code—but what actually happens behind interfaces such as JpaRepository? In this video, we build Spring Data JPA from first principles. We begin with the repository boilerplate left after learning Hibernate and JPA, then understand how Spring creates repository implementations dynamically using proxies and SimpleJpaRepository. You will learn: Spring Data versus Spring Data JPA JPA versus Spring Data JPA Complete persistence-layer architecture Repository, CrudRepository and JpaRepository Repository proxy and SimpleJpaRepository internals How save(), findById() and delete() work internally persist() versus merge() save() versus JPA dirty checking Derived query methods Query keywords such as Containing, Between, Top and OrderBy Custom JPQL queries using @Query Named and positional parameters Implicit and explicit joins Native SQL queries Dynamic sorting using Sort Pagination using Pageable and PageRequest Page versus Slice Count queries and pagination performance By the end, you will understand not only how to use Spring Data JPA repositories, but also how they work internally with EntityManager, Hibernate and the database.
