Thymeleaf: how to get URL attribute value

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.

I tried this and it's working for me :

<div th:if="${param.error !=null}" class="col-xs-12 form-group">
       
</div>

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>

<a th:href="@{somesite.com/login(error = ${#httpServletRequest.getParameter('error')}"><a>

This may work.

Another way of accessing request parameters in thymeleaf is by using #httpServletRequest utility object which gives direct access to javax.servlet.http.HttpServletRequest object.

An example usage with null checking looks like,

<div th:text="${#httpServletRequest.getParameter('error')}" 
     th:unless="${#httpServletRequest.getParameter('error') == null}">
    Show some error msg
</div>

This is same as doing request.getParameter("error"); in java.
