Example Card API

Demo Spring Boot Rest API, showing how to use some useful Spring features.

Included features

• In memory database using H2, using JPA for ORM.
• A RESTful API, with CRUD operations for handling users and cards.
• API includes allowing users to request cards, validating them, and generating image representations of them.
  • (note cards are intentionally missing some CRUD operations, as they are treated as immutable)
• Strong tests using functionality such as MockMVC for testing endpoints, and ApplicationContextRunner for tests involving Spring Context.
• Also includes Swagger UI setup to view endpoints.
