Working with spring boot 3 and thymeleaf. I have a base layout for my dashboard which has some link items. I want to give the currently active link an "active" bootstrap class appended to it. How do i get the current url in my thymeleaf template?
I tried this but i keep getting errors in the log
th:classappend="${#request.getRequestURI() == '/application'? 'active': ''}"
