Well, let’s move on to the most exciting part and write our own REST API. I recommend coding along as you watch the video for a better understanding.

Let’s create a simple RESTful API for a bookstore using Spring Boot. We will include all the necessary components: models, repositories, services, controllers. The API will support creating, reading, updating, and deleting books.

Short Clip From the Video

In our REST API, we defined the model we’ll be working with (Book model), which includes the following fields:

We also implemented endpoints for our application, which we will test in the following chapters.

Examples of the endpoints:

• GET /books — retrieves all books (findAllBooks() method);
• POST /books — creates a new book (createBook() method);
• PUT /books/{id} — updates a book with the specified ID (updateBook() method);
• DELETE /books/{id} — deletes a book with the specified ID (deleteBook() method).
