Summary of Changes

Hello @rashidi, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request adds a new module that serves as a comprehensive example of integrating JDBI with a Spring Boot application. It establishes a foundational data access layer for simple entities, demonstrating JDBI's declarative SqlObject API for defining repositories and leveraging Testcontainers to provide an ephemeral PostgreSQL database for integration tests. The changes aim to provide a clear blueprint for using JDBI in a modern Spring Boot context.

Highlights

• New JDBI Module: A new jdbi module has been introduced to the project, providing a dedicated example for JDBI integration.
• JDBI Integration with Spring Boot: This pull request demonstrates how to integrate JDBI with a Spring Boot application, including repository definitions using JDBI's SqlObject API and custom RowMapper implementations.
• PostgreSQL and Testcontainers Setup: The example utilizes PostgreSQL as the database and incorporates Testcontainers for robust and isolated integration testing, ensuring a consistent test environment.
• Example Data Access Layer: It includes Author and Book entities, along with an AuthorReadOnlyRepository to showcase basic CRUD-like operations (specifically read operations) using JDBI.

Code Review

This pull request adds a new example project demonstrating the use of JDBI with Spring Boot. The overall structure is good, with a clear separation of concerns, use of modern Java features, and integration tests using Testcontainers. I've provided a few suggestions to improve the code further, including using modern Jakarta EE dependencies, converting a class to a record, improving repository method signatures for safety, and refining the test setup for clarity and reproducibility. These changes will enhance the maintainability and robustness of the example.
