Summary
In this chapter, we used JPA to create our Spring Boot application database. First, we created entity classes, which are mapped to database tables. Then, we created CrudRepository for our entity class, which provides CRUD operations for the entity. After that, we managed to add some demo data to our database by using CommandLineRunner. We also created one-to-many relations between two entities. At the beginning of the chapter, we used the H2 in-memory database, while, at the end, we switched the database to MariaDB.
In the next chapter, we will create a RESTful web service for our backend. We will also look at testing the RESTful web service with the curl command-line tool, and also by using Postman GUI.
