Architecture

The framework is built on top of Spring Boot, Spring MVC, Spring Data JPA, and Spring Security, providing a robust suite of tools for developing REST APIs. The core components are as follows:

Controller Layer

This layer consists of generic controllers that provide common implementation for different types of requests:

• GenericListController

• GenericCreateController

• GenericDeleteController

• GenericRetrieveController

• GenericUpdateController

• GenericCommandController

• GenericQueryController

These controllers help in structuring API endpoints for CRUD operations in a reusable and modular way.

Service Layer

This layer contains two service classes operating as business logic:

• CommandService – Handles commands related to modifications (Create, Update, Delete).

• QueryService – Handles data retrieval operations.

Utility Layer

This layer provides tools used in the service layer:

• DtoManager – Manages Data Transfer Objects.

• SwaggerSchemaGenerator – Generates API documentation using Swagger.

• EntityBuilder – Helps construct entity objects.

• SpecificationsBuilder – Builds query specifications dynamically.

FilterSet and Serializer:

• FilterSet – Defines filtering rules for querying data.

• Serializer – Handles object serialization and deserialization.

The entire structure is built upon Spring Framework, leveraging its powerful features for dependency injection, security, and configuration.
