最后是我的胸腺嘧啶代码：

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<body>
<h1 th:text="${workout.exerciseName}"></h1>

</body>
</html>
如果您能提供任何帮助，我们将不胜感激。

您的代码似乎有误。尝试：

<h1 th:text="${workout.exName}"></h1>
您在HTML中使用了错误的属性。对象训练是一个列表，因此需要对其进行迭代以访问训练对象

<div th:each="workoutItem : ${workout}">
    <span th:text="${workoutItem.exName}"></span>
</div>
正如@juanlumn所说，您没有任何名为exerciseName的属性，请在您的帖子中添加Thymeleaf代码和完整的异常堆栈跟踪。另外，我在任何地方都没有看到
exerciseName
的getter。欢迎访问SO。也添加你的
训练
