胸腺变量

Question

有没有办法告诉Thymeleaf如果任何字段有错误，请显示错误消息？

我目前将它们单独列出，如下所示：

<div th:if="${#fields.hasErrors('password')}" th:errors="*{password}" class="validation-message alert alert-danger" role="alert"></div>
<div th:if="${#fields.hasErrors('lastName')}" th:errors="*{lastName}" class="validation-message alert alert-danger" role="alert"></div>
<div th:if="${#fields.hasErrors('firstName')}" th:errors="*{firstName}" class="validation-message alert alert-danger" role="alert"></div>

应该能够执行以下操作：

<div th:each="err : ${#fields.errors('*')}" class="validation-message alert alert-danger" role="alert" th:text="${err}" />
