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

## Application user details

We have seen in the earlier modules that we can show the username on a Thymeleaf page using `sec:authentication="name"` and the roles of the user with `sec:authentication="principal.authorities"`.

The principal refers to the `UserDetails` implementation that the `UserDetailsService` returns. We can call any method of our `ApplicationUserDetails` implementation in the `sec:authentication` attribute to display information about the current user.

## Updating menu
As an example, we can update `top-menu.html` to show the `displayName` and the `username` information from `ApplicationUserDetails`:
