我想要实现的目标很简单：
<form action="/matrix/${matrix.name}/add-task">
但是我无法让Thymeleaf将matrix.name的值放入我的表单中。
我尝试了th:inline：
<form th:inline="text" action="/matrix/[[${matrixName}]]/add-task">
th:with：
<form th:with="matrixName=${matrix.name}" action="/matrix/${matrixName}/add-task">
th:action：
<form th:action="@{/matrix/__${matrix.name}__/add-task">
但没有任何作用。值保持${matrix.name}并且不会被替换，或者在后一种情况下（th:action）我得到一个例外：

Thymeleaf让我发疯。如何使用简单的变量内联来使用此模板引擎？
