Overview
Spring Data JPA simplifies database access in Spring Boot applications by providing repository abstractions over JPA (Java Persistence API).
Getting Started
Before diving into Spring Data JPA development, get up and running:
- Initial Setup - Install Java/Kotlin, Spring Boot, configure database connection, H2/PostgreSQL setup
- Quick Start - Your first entity and repository, basic CRUD operations, essential patterns
These foundational tutorials (0-30% coverage) prepare you for comprehensive Spring Data JPA learning in both Java and Kotlin.
What You’ll Learn
- Entities - Map Java/Kotlin classes to database tables with JPA annotations
- Repositories - Define data access interfaces with Spring Data JPA conventions
- Query Methods - Write queries using method naming conventions (findByNameAndAge)
- JPQL Queries - Write custom queries using Java Persistence Query Language
- Specifications - Build type-safe dynamic queries with Criteria API
- Relationships - Model associations (OneToMany, ManyToOne, ManyToMany)
- Transactions - Manage database transactions declaratively with @Transactional
- Production Patterns - Connection pooling, lazy loading, caching, pagination
