Advanced Spring Boot Template Application

This project is a comprehensive Spring Boot template designed to serve as a robust foundation for any Spring Boot-based application. It incorporates industry-standard configurations and features, providing a scalable, secure, and high-performance starting point.

Features

1. Security and Authentication

• JWT Authentication: Implemented Spring Security using JWT tokens for stateless authentication.
• Role-Based Access Control (RBAC): Configured roles and access controls for different API endpoints.
• CSRF Protection: Enabled for stateful web applications (e.g., forms). Disabled for stateless REST APIs secured with JWT tokens, where CSRF protection is not necessary.

2. API Documentation

• Swagger/OpenAPI: Configured Swagger for API documentation to provide a user-friendly interface for exploring and testing APIs.

3. Database Integration

• JPA/Hibernate: Set up JPA for ORM and database interaction to ensure smooth data persistence.

4. Exception Handling

• Global Exception Handling: Centralized exception handling using @ControllerAdvice, allowing for consistent error responses across the application.

5. Logging and Monitoring

• Spring Boot Actuator: Integrated Actuator to monitor the application’s health and performance metrics.
• SLF4J with Log4j2: Configured for advanced logging capabilities, providing detailed logs for easier debugging and analysis.

6. Configuration Management

• External Configuration: Managed externalized configurations using application.properties and application.yml for flexible environment-specific settings.
• Profiles: Configured environment-specific profiles (dev, test, and prod) to handle different runtime configurations.

7. Asynchronous Processing

• Spring Async: Implemented asynchronous task execution using @Async to improve performance and scalability where applicable.
• Scheduling: Enabled scheduled task execution using @Scheduled for periodic jobs.

8. Caching

• Spring Cache: Integrated Spring Cache abstraction to enhance performance by caching frequently accessed data.
• Cache Providers: Configured with cache providers like Ehcache or Redis for optimized caching solutions.

9. File Handling

• AWS S3 Integration: Integrated AWS S3 for storing and retrieving profile pictures, ensuring reliable and scalable file storage.

10. Email Integration

• Spring Email: Configured email sending using Spring Email to facilitate user notifications, such as account activation and password reset emails.

11. WebSocket Support

• Spring WebSocket: Implemented real-time communication using WebSockets. Though not utilized in the current project, the WebSocket configuration is ready for future extensions.

12. Correlation ID

• Correlation ID Header: Added correlation IDs to all API headers to track requests across services and ensure better traceability.

Getting Started

Prerequisites

• Java 11 or higher
• Maven
• AWS credentials for S3 integration
• SMTP server for email integration

Installation

• 1. Clone the repository:

git clone https://github.com/your-repo/advanced-spring-boot-template.git
cd advanced-spring-boot-template

• 2. Configure the application properties: Update the application.properties or application.yml with your environment-specific settings, including database connections, S3 credentials, and email server configurations.
