wallanpsantos/ms-product-catalog

This system is a product catalog service built on a hexagonal architecture with a CQRS-lite pattern, now persisted in PostgreSQL instead of MongoDB. It manages product lifecycles including creation, updates, deactivation, and search, with a domain layer that is decoupled from the underlying database technology. The codebase enforces architectural rules and includes comprehensive test coverage across unit, integration, and end-to-end scenarios.

The Gradle wrapper has been upgraded from version 9.3.1 to 9.4.1, ensuring that the project uses the specified stable distribution for builds.

The application's persistence layer has been migrated from MongoDB to PostgreSQL. This involves replacing the previous MongoDB-specific adapters (ProductMongoQueryAdapter, ProductMongoCommandAdapter) with new JPA-based implementations (ProductJpaQueryAdapter, ProductJpaCommandAdapter) and corresponding JPA entities and repositories. The domain layer was updated to use Java's \Instant\ instead of \LocalDateTime\ for timestamps, and the pagination mechanism was decoupled from Spring Data's \Pageable\/\Page\ in favor of domain-specific \Pagination\ and \SearchQuery\ records to ensure the core domain remains independent of the underlying database technology.

Added architecture and unit test coverage for the catalog module; Added end-to-end tests for the product API; Added tests for ProductJpaEntity and its repository; Added tests for product JPA adapters; Added unit and integration tests for catalog application use cases; Added unit tests for domain validation and product logic; Configures Testcontainers for local Windows development; Updated test infrastructure to use PostgreSQL instead of MongoDB.

The project upgrades Spring Boot from version 4.0.3 to 4.0.5 and Testcontainers from 1.21.4 to 2.0.5. The Java toolchain target is raised from 21 to 25. The database dependency shifts from MongoDB to PostgreSQL (using spring-boot-starter-data-jpa and the PostgreSQL driver). Test dependencies are updated to use testcontainers for PostgreSQL and Kafka, and the JUnit platform is explicitly configured. Additionally, the build configuration enables Gradle's configuration cache, parallel execution, and daemon, while adding SonarQube integration and specific JaCoCo coverage exclusions.
