Overview of this book

Getting started with full stack development can be daunting. Even developers who are familiar with the best tools, such as Spring Boot and React, can struggle to nail the basics, let alone master the more advanced elements. If you’re one of these developers, this comprehensive guide covers everything you need! This updated edition of the Full Stack Development with Spring Boot 2 and React book will take you from novice to proficient in this expansive domain. Taking a practical approach, this book will first walk you through the latest Spring Boot features for creating a robust backend, covering everything from setting up the environment and dependency injection to security and testing. Once this has been covered, you’ll advance to React frontend programming. If you’ve ever wondered about custom Hooks, third-party components, and MUI, this book will demystify all that and much more. You’ll explore everything that goes into developing, testing, securing, and deploying your applications using all the latest tools from Spring Boot, React, and other cutting-edge technologies. By the end of this book, you'll not only have learned the theory of building modern full stack applications but also have developed valuable skills that add value in any setting.

  1. ORM is a technique that allows you to fetch and manipulate data from a database using an object-oriented programming paradigm. JPA provides object-relational mapping for Java developers. Hibernate is a Java-based JPA implementation.
  2. The entity class is just a standard Java class that is annotated with the @Entity annotation. You have to implement constructors, fields, getters and setters inside the class. The unique ID field(s) are annotated with the @Id annotation.
  3. You have to create a new interface that extends the Spring Data CrudRepository interface. You define the entity and the type of the id field in the type arguments—for example, <Car, Long>.
  4. The CrudRepository provides all CRUD operations to your entity. You can create, read, update, and delete your entities using the CrudRepository.
  5. You have to create entity classes and link the entities using the @OneToMany and @ManyToOne annotations.
  6. You can add demo data to your main application...
