java - Thymeleaf: how to get URL attribute value

Question

I can't find any solution for getting attribute from URL using Thymeleaf. For example, for URL:

somesite.com/login?error=true

I need to get "error" attribute value. Also I'm using SpringMVC, if it could be helpful.

Answer 1

After some investigation I found that it was Spring EL issue actually. So complete answer with null checking is:

<div id="errors" th:if="${(param.error != null) and (param.error[0] == 'true')}">
    Input is incorrect
</div>
