broadcom-test project description

broadcom-test project is java spring boot REST API application with maven build script. This application represents vending machine emulation.

1. Project structure

Project contain 3 modules

Main core classes with model, repository and business logic layers.

Core is not dependent on data persistence
Core is not dependent on data visualization and population
Business logic is not thread-safe or transactional because responsibility on this lays on core's consumers and can depend on repository implementation

Module contains in-memory repositories implementation.

Current implementation contains only in-memory storage for easy deploy.
You can easily autowire repository beans with Hibernate JPA, DynamoDB, no-sql, TCP/IP or other implementation to change persistence behavior.

This module represents REST API application. It has dependencies on core and storage modules.

Switch dependency from broadcom-storage to another storage implementation.
Make ApiService class transactional by adding @Transactional annotation. Because the responsibility of core's usage lays on this class as on the only consumer.
