• Spring Data JPA Interfaces: A comprehensive overview of essential Spring Data JPA interfaces.
• Spring Data JPA Configuration: Practical guidance on configuring Spring Data JPA within your Spring projects.
• Query Methods: Master the creation of custom query methods for flexible data retrieval.
• Named Queries & Native Queries: Learn to utilize named queries and native SQL queries for complex database interactions.
• The @Query Annotation: Effectively use the @Query annotation to define and execute database queries.
• Query by Example: Efficiently execute queries using example objects.
• Entity Graph: Understand and apply Entity Graphs for optimized data retrieval and relationships.
• Spring Data JPA: Paging & Sorting: Implement pagination and sorting to efficiently handle large datasets. Learn to combine these techniques for refined data presentation.
• Spring with Flyway: Database Schema Management: Explore various methods for managing your database schema. Discover Flyway, a popular tool for version controlling database migrations.
• Flyway Configuration & Migrations: Learn how to configure Flyway and manage database migrations effectively.
• Spring Data JPA Testing: Implement comprehensive testing strategies for your persistence layer.
  • Unit Tests: Create and execute unit tests for your data access logic.
  • Integration Tests: Configure and utilize both in-memory and shared databases for integration testing.
  • Testcontainers: Leverage Testcontainers for streamlined integration testing.

Workshop Structure:

This workshop is the 17th in the Zajavka learning path, but can be studied independently. The materials are built using Java 17, and tests are also designed for Java 17. We'll concentrate on Spring, not the latest Java features. While some elements demonstrate Spring 5 and others Spring 6, the core concepts remain applicable regardless of the Spring version.

Practical Application:

The workshop culminates in a practical project and challenging tasks to solidify your understanding of Spring Data JPA. Gain hands-on experience applying these skills to real-world scenarios.
