Get started with the basics of Thymeleaf and Spring Boot and how to use them to create scalable applications.

Spring Boot Development for Java Programmers

This module will teach us how to build easily scalable applications with Thymeleaf and Spring Boot. We will combine Thymeleaf and Spring Boot with Spring Data and Spring Security.

This module will give us all the basics for developing an application using Thymeleaf and Spring Boot. Throughout the module, we will build an application of a fictional basketball team called Thyme Wizards. We will also learn to use unit and integration tests to ensure proper code functionality and create a maintainable code base that we can expand upon.

By the end of this module, we will have some great new skills working with the Spring Boot framework, which employers will love.

Building Scalable Applications with Thymeleaf and Spring Boot

Layouts can have parameters, just like fragments.
To show how this works, we will create an admonition fragment:



<!DOCTYPE html>
<html
  xmlns:th="http://www.thymeleaf.org"
  xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
>
  <body>
    
    <div
      layout:fragment="admonition(type)"
      class="flex mb-4 p-2 w-2/4"
      th:classappend="${type == 'NOTE'?'bg-yellow-100':'bg-blue-100'}"
    >
      <div th:text="${type}" class="mr-4"></div>
      <div layout:fragment="message"></div>
    </div>
  </body>
</html>

## Defining the fragment
Since we want to only use the `<div>`  and it's children rather than the full HTML page, we define a fragment name using `layout:fragment`. We also specify that the layout takes a `type` parameter. 

If the parameter has the value `NOTE`, we color the background `yellow`. Otherwise, we color the parameter `blue`.

We can use the template like this:
