Spring Data JPA by Baekgi-seon
Learn about Spring Data JPA, which provides several features to make using JPA (Java Persistence API) easier.
Why should I learn JPA?
- Domain-driven development is possible.
- Prevents your application code from being consumed by SQL database-related code and allows you to focus on implementing business logic with domain-driven programming.
- And 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.
With all these advantages, one drawback of JPA is its high learning curve.
I hope this lecture will help lower that learning cost a little.

The following content
I am 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 will learn the important features of JPA and Hibernate, which are ORM implementations. In particular, you need to understand the fetching strategy and the life cycle of entities to be able to program JPA while considering performance.
Next, we will look at the magical bean creation method of Spring Data JPA. After learning the core concept principles, we will look at various ways to use Spring Data JPA in earnest. We will look at the functions provided by default and learn various customization and various technology integration methods.
