In this tutorial, you’re going to use Spring Boot and Spring Data to build a fully functioning web service with ridiculously little effort. You’re also going to use Okta to secure the web service using professional, standards-compliant OIDC JWT authentication.
All of this means that, as you will see, with a few simple files, you can define your data model using a Java class, seamlessly persist it to a database, and expose that data in a secure RESTful web service.
This is the interface that will leverage Spring Data JPA to read and write the Dinosaur instances to and from the in-memory database.
In this tutorial, you took a look at Spring Data in general and saw how it is an umbrella project.
