4) How to Connect SpringBoot Backend with Frontend: Step-by-Step. Thymeleaf (as a registration form)

In this step-by-step tutorial, you will learn how to connect a Spring Boot backend with a frontend using Thymeleaf as a registration form. Thymeleaf is a server-side Java template engine that allows us to create dynamic HTML pages with ease. We will start by creating a basic Spring Boot project and then build a simple registration form on the frontend using HTML and Thymeleaf.

Next, we will create a controller in our Spring Boot application to handle requests from the frontend and communicate with the database. We will use Thymeleaf templates to display the registration form on the frontend and also to submit new user data to be inserted into the database.

Throughout the tutorial, we will explain each step in detail and provide code examples to make it easy to follow along. By the end of the tutorial, you will have a solid understanding of how to connect a Spring Boot backend with a frontend using Thymeleaf as a registration form.
