Overview of this book

React Hooks have changed the way React components are coded. They enable you to write components in a more intuitive way without using classes, which makes your code easier to read and maintain. Building on from the previous edition, this book is updated with React Hooks and the latest changes introduced in create-react-app and Spring Boot 2.1. This book starts with a brief introduction to Spring Boot. You’ll understand how to use dependency injection and work with the data access layer of Spring using Hibernate as the ORM tool. You’ll then learn how to build your own RESTful API endpoints for web applications. As you advance, the book introduces you to other Spring components, such as Spring Security to help you secure the backend. Moving on, you’ll explore React and its app development environment and components for building your frontend. Finally, you’ll create a Docker container for your application by implementing the best practices that underpin professional full stack web development. By the end of this book, you’ll be equipped with all the knowledge you need to build modern full stack applications with Spring Boot for the backend and React for the frontend.

Using JPA to Create and Access a Database

This chapter covers how to use Java Persistent 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 in-memory database for development and demonstration purposes. H2 is an in-memory SQL database that is really good for fast development or demonstration purposes. In the second phase, we will move from H2 to use 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 Object-Relational Mapping (ORM), JPA, and Hibernate
  • Creating the entity classes
  • Creating CRUD repositories
  • Relationships between tables
  • Setting up the MariaDB database
