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

## Controller specific

If we look at the various methods in `UserController`, we'll see that some of the `model` attributes are
added to the `model` in each method.
Let’s look at a single method for reference:

@GetMapping("/create")
@Secured("ROLE_ADMIN")
public String createUserForm(Model model) {
    model.addAttribute("user", new CreateUserFormData());
    model.addAttribute("genders", List.of(Gender.MALE, Gender.FEMALE, Gender.OTHER));
    model.addAttribute("possibleRoles", List.of(UserRole.values()));
    model.addAttribute("editMode", EditMode.CREATE);
    return "users/edit";
}

The `genders` and `possibleRoles` attribute is also added in three other methods of the `UserController`. We could, of course, just create a method and call that method from all places, but there is also another way. We can add a method annotated with `@ModelAttribute` in `UserController`.
