thymleaf分支用法

<div th:switch="${user.role}"> 

  <p th:case="'admin'">User is an administrator</p>

  <p th:case="#{roles.manager}">User is a manager</p>

  <p th:case="*">User is some other thing</p> 

</div>



<div th:with="condition=${potentially_complex_expression}" th:remove="tag">

    <h2 th:if="${condition}">Hello!</h2>

    <span th:unless="${condition}" class="xxx">Something else</span>

</div>



wrong：

<div th:if="${condition}" th:replace="path/to/fragment : #fragmentId"></div>
