What if Spring JPA feels difficult? Learn concepts, principles, and even practice thoroughly.
Learning properly Baek Gi-seon's Spring Data JPA
Learn about Spring Data JPA, which provides several features to make JPA (Java Persistence API) easier to use.
Why should I learn JPA?
Domain-driven development is possible.
Prevent your application code from being consumed by SQL database-related code, and focus on implementing business logic with domain-driven programming.
It's great for development productivity, allows for database-independent programming, allows for type-safe query writing, and even optimizes performance with the cache functionality provided by Persistent Context.
Despite these many advantages, JPA has one drawback: its high learning curve. I hope this lecture will help lower the cost of learning even a little.
Who will find this lecture helpful ?
JPA or Hibernate Getting started with programming Student or Developer
ORM and JPA and Spring Data JPA For those who want to understand the principle
Spring Data JPA If you are using it for the first time or For those who want to make better use of it
The following content I'm learning.
📖 Spring Data JPA → JPA (Hibernate) → JDBC
In this lecture, we will first learn about the problem that ORM (Object-Relational Mapping) is trying to solve, namely the conceptual mismatch between objects and relational databases .
Next, we'll learn the key features of JPA and Hibernate, ORM implementations. In particular, understanding fetching strategies and entity lifecycles is crucial for JPA programming with performance in mind.
Next, we'll explore Spring Data JPA's magical bean creation method . After learning the core concepts and principles, we'll delve into the various ways to utilize Spring Data JPA. We'll begin by examining the default features and then explore various customization and technology integration methods.
Learning Objectives Please check it out.

스프링부트 혼자서 documentation 공부하다가 우연히 유투브로 백기선님 알게 되었어요... 인프런에서 백기선님 강의를 알게 되어서 여러개 수강 중인데... 왜 이런지 개념을 설명해주셔서 정말 좋습니다. 결제한 강의 다 듣게 되면은 스프링시큐리티 수업도 듣고 싶네요... 강의 너무 좋아서 회사 동료분들께 마구마구 추천중입니다... 좋은 강의 만들어주셔서 감사합니다.
