I have this code that already works:

<span class="label" th:classappend="${usuario.ativo ? 'label-success' : 'label-danger'}"> </span></td>

But now I want the following:

    <span class="label" th:classappend="${usuario == vazio ? 'label-success' : 'label-danger'}"> </span></td>

If the user is empty, the label will get label-danger

but it did not work because I was wrong ... could anyone help me?

Try the modification below. If it's just this, okay. If not, you need to add more information to the question, my friend.

 <span class="label" th:classappend="${usuario == null ? 'label-success' : 'label-danger'}"> </span></td>
