Overview of this book

If you’re an existing Java developer who wants to go full stack or pick up another frontend framework, this book is your concise introduction to React. In this three-part build-along, you’ll create a robust Spring Boot backend, a React frontend, and then deploy them together. This new edition is updated to Spring Boot 3 and includes expanded content on security and testing. For the first time ever, it also covers React development with the in-demand TypeScript. You’ll explore the elements that go into creating a REST API and testing, securing, and deploying your applications. You’ll learn about custom Hooks, third-party components, and MUI. By the end of this book, you'll be able to build a full stack application using the latest tools and modern best practices.

Using DI in Spring Boot

In Spring framework, the dependency injection is achieved through the Spring Application Context. Application context is responsible for creating and managing objects (beans) and their dependencies. Spring Boot scans your application classes and registers classes with certain annotations (@Service, @Repository, and @Controller) as Spring beans. These beans can then be injected using an @Autowired annotation:

public class Car {
  @Autowired
  private Owner owner;
  ...
}

A fairly common situation is where we need database access for some operations, and, in Spring Boot, we use repository classes for that. In this situation, we can inject the repository class and start to use its methods:

public class Car {
  @Autowired
  private CarRepository carRepository;
    // Fetch all cars from db 
carRepositoty.findAll();
...
}

Jakarta EE (jakarta.annotation) also provides a @Resource annotation that can be used for injections. You can define the name or type of the injected...
