Data Persistence with Spring Boot and Spring Data JPA

Managing database interactions in Java applications can often lead to repetitive boilerplate code. Spring Data JPA simplifies this by providing a robust repository abstraction that lets you focus on business logic instead of manual SQL queries. This text-based course guides you through setting up and optimizing your data access layer. You will transition from writing manual database queries to leveraging automated repository interfaces, handling relationships, and implementing modern persistence patterns. What you'll learn: 1. Understand the core concepts of Object-Relational Mapping (ORM) and Spring Data JPA. 2. Configure Spring Boot applications to connect with H2 in-memory databases and external databases. 3. Create and customize repository interfaces using query methods and JPQL. 4. Manage database relationships including one-to-many and many-to-many mappings. 5. Implement modern Java practices such as using Records for Data Transfer Objects (DTOs). 6. Write repository tests using specialized testing annotations to ensure data integrity. You will begin by learning fundamental database concepts and setting up your first Spring Boot project. From there, you will progress through defining entities, writing custom queries, managing transaction boundaries, and testing your repository layer using modern practices. This course is designed for beginner Java developers and Spring enthusiasts who want to master database integration. No prior experience with JPA or Hibernate is required, though a basic understanding of Java is recommended. Start reading today to streamline your application's database interactions.
