📜 Recent Updates

Commit Message: Initial Project Setup and HomeController Addition

Commit Details:

• HomeController: A new HomeController class has been added to handle requests for the home page. This controller is responsible for managing primary interactions on the main page of the application.
• Initial Project Setup:
  • .gitignore: Specifies files and directories to ignore in git operations.
  • Maven Wrapper Files (.mvn/, mvnw, mvnw.cmd): Enables easy Maven build execution without installing Maven.
  • pom.xml: Maven Project Object Model for dependency and build configuration.
  • TechNexusHubApplication.java: Main application class that bootstraps the Spring Boot application.
  • src/main/resources/: Contains configuration and static files.
  • src/test/: Includes test classes to ensure the application functions correctly.

🔄 How It Works

1. Request Flow

• The user sends a request (e.g., viewing a product or placing an order).
• The request is routed through a Controller, which handles business logic with the help of Services and interacts with Repositories for database operations.

2. Business Logic

• Services handle the application's core logic.
• Services fetch and process data using Repositories and return processed data to the Controller.

3. Database Interaction

• Entities map to database tables.
• Repositories use Spring Data JPA to interact with the database for CRUD operations.

4. Error Handling

• Exceptions are managed globally through the GlobalExceptionHandler, ensuring consistent error responses across the application.

5. Custom Features

• Custom Validation: Validators in the validate package enforce business rules (e.g., image name restrictions).
• Data Transfer Objects: DTOs streamline data exchange between layers while maintaining abstraction.
