About the author

Juha Hinkula is a software development lecturer at Haaga-Helia University of Applied Sciences in Finland. He received an MSc degree in Computer Science from the University of Helsinki and has over 17 years of industry experience in software development. Over the past few years, he has focused on modern full stack development. He is also a passionate mobile developer with Android-native technology, and he uses React Native.

I am really proud of the Packt editorial team for their outstanding work. Your constructive feedback and dedication have made this journey truly exceptional.

I would also like to give special thanks to my editor, Lucy Wan. Your ability to provide constructive feedback and offer suggestions for improvement has been invaluable.

I want to extend my gratitude to our technical reviewers, Dirk and Jose, for helping me grow as a writer and author. Your deep knowledge, attention to detail, and commitment to excellence have elevated my work beyond my expectations.

Finally, I want to thank my wife and daughter for the time and space you've given me for writing.

About the reviewers

Dirk Wichmann is a software architect who has been working in IT for more than 20 years. Professionally, he deals mainly with topics relating to security and architecture. He has worked for various companies across the fields of energy supply, water, logistics, healthcare, and security. As a senior IT specialist, Dirk’s knowledge naturally includes the modern technology stack (for instance, Docker, Keycloak, and Jenkins). He loves agile approaches and clean code, as well as domain-driven design.

Since the very beginning, Dirk has used Java and Spring in the development and design of software, but he is interested in all areas of the development process – backend, frontend, testing, operations, and so on. In recent years, he has focused increasingly on microservices with Spring/Spring Boot in the backend and React in the frontend.

Jose Galdamez has worked on full stack web app projects since the year 2000, across a variety of organizations in the public sector, private sector, and academia. While he has spent most of that time working with loosely typed languages like JavaScript, PHP, and Perl, he has come around more to utilizing strongly typed systems like TypeScript and Java. The bulk of his expertise lies in updating legacy systems to be more reliable, maintainable, scalable, and user-friendly. Jose currently works as a software engineer for Clarity Innovations.

This publication is the first on which Jose has had the chance to collaborate, and it is also one that he read and benefited from as a consumer, for his previous work.

I’d like to thank my wife and two children for being loving and patient with me while I spent evenings and weekends ensuring every last detail for this book was perfect. I would also like to recognize my employer, Clarity Innovations, for pushing me to exceed what I thought was possible as an engineer while being surrounded and cheered on by the best minds in the business.

Part I

Backend Programming with Spring Boot

3

Using JPA to Create and Access a Database

This chapter covers how to use Jakarta Persistence API (JPA) with Spring Boot and how to define a database by using entity classes. In the first phase, we will be using the H2 database. H2 is an in-memory SQL database that is good for fast development or demonstration purposes. In the second phase, we will move from H2 to MariaDB. This chapter also describes the creation of CRUD repositories and a one-to-many connection between database tables.

In this chapter, we will cover the following topics:

Basics of ORM, JPA, and HibernateCreating the entity classesCreating CRUD repositoriesAdding relationships between tablesSetting up the MariaDB database

Technical requirements

The Spring Boot application we created in previous chapters is required.

A MariaDB installation is necessary to create the database application: https://downloads.mariadb.org/. We went through the installation steps in Chapter 1.

The code for this chapter can be found at the following GitHub link: https://github.com/PacktPublishing/Full-Stack-Development-with-Spring-Boot-3-and-React-Fourth-Edition/tree/main/Chapter03.

Basics of ORM, JPA, and Hibernate

ORM and JPA are widely used techniques in software development for handling relational databases. You don’t have to write complex SQL queries; instead, you can work with objects, which is more natural for Java developers. In this way, ORM and JPA can speed up your development process by reducing the time you spend writing and debugging SQL code. Many JPA implementations can also generate a database schema automatically based on your Java entity classes. In brief:

Object-Relational Mapping (ORM) is a technique that allows you to fetch from and manipulate
