java - Thymeleaf 使用路径变量到 :href

Question

这是我的代码，我正在迭代:

<tr th:each="category : ${categories}">
     <td th:text="${category.idCategory}"></td>
     <td th:text="${category.name}"></td>
     <td>
         <a th:href="@{'/category/edit/' + ${category.id}}">view</a>
     </td>
</tr>

它指向的 URL 应该是 /category/edit/<id of the category> ，但它说它无法解析表达式:

Exception evaluating SpringEL expression: "category.id" (category-list:21)

Answer 1

根据Thymeleaf documention for adding parameters的正确方法是:

<a th:href="@{/category/edit/{id}(id=${category.idCategory})}">view</a>
