How to append a css class if user has specific role?

Question

How to append a class to an element with th:classappend only if the user has a specific role?

Something like this:

<div th:classappend="${hasRole('EDITOR')?'glow':''}"></div>

I'm using Spring Boot, Spring Security and Thymeleaf.

Answer 1

I found the solution on Thymeleaf "extras" Spring Security GitHub page:

<div th:classappend="${#authorization.expression('hasRole(''EDITOR'')')?'glow':''}"></div>

Answer 2

You can use the request variable, which points to the current HttpServletRequest:

<div th:classappend="${#request.isUserInRole('EDITOR')?'glow':''}"></div>
