Welcome to the Spring Boot Best Practices Application! This project serves as a comprehensive demonstration of fundamental Java Spring concepts, highlighting industry best practices and essential techniques for building robust Spring Boot applications. The project is designed to be a reference for developers of all levels, providing examples of a wide range of Spring Boot features and implementations.

• Model-View-Controller (MVC) Architecture: Embracing the MVC pattern for a well-organized and modular structure.
• MapStruct for Object Mapping: Streamlining object mapping for enhanced readability and maintainability.
• Flyway for Database Migration: Seamless database migration management through Flyway.
• JUnit 5 Configuration: Configured JUnit 5 for effective testing and robust code coverage.
• JSON Data Processing: Efficiently reading and filtering data from JSON files.
• Basic CRUD Operations: Implementation of essential CRUD operations for effective resource management.
• Pageable Response Handling: Demonstrating easy filtering, sorting, and more with Pageable responses.
• Global Exception Handling: A global exception handler for managing exceptions across the codebase.
• Custom Spring Validator: Examples of custom Spring validators at field and class levels.
• CriteriaBuilder for Data Retrieval: Using CriteriaBuilder for advanced data retrieval.
• Spring Boot Actuator: Configuring Spring Boot Actuator for collecting application metrics.
• Git Information Injection: Injecting Git information into Spring for version tracking.
• Quartz Scheduler: Implementation of Quartz scheduler using Cron Triggers and Expressions.
• Spring Custom Events: Leveraging Spring Custom Events for event-driven architecture.

• Integrated with GitHub Actions for code analyses with SonarCloud and Codecov for code coverage reports.
• Integrated with Docker. On every push event to the main branch, a new Docker image is generated.
• Integrated with Maven Dependency tree generation.
