Overview

This repository provides a robust starting point for Spring Boot 3 projects, including multi-database support, advanced transaction management, real-time capabilities, and best practices for modern Java development.

Implemented Features

• Multi-database configuration and multiple transaction managers (support for connecting and managing more than one database, handling transactions across multiple databases)
• Real-time integration with Firebase
• Base entity, base controller, base service, and common mapper for code reusability
• Spring Data JPA for data access
• Spring Web for building RESTful APIs
• Spring Security for authentication and authorization
• MapStruct and Lombok integration for DTO/entity mapping and reduced boilerplate
• Jakarta Validation API and Hibernate Validator for bean validation
• Swagger/OpenAPI documentation (SpringDoc)
• SonarQube Maven Plugin for code quality analysis
• Docker & Docker Compose support for containerization
• Spring Boot DevTools for enhanced development experience
• Spring Boot Actuator for monitoring and management
• Internationalization (i18n) support
• Excel import/export functionality
• Logging with AOP
