<p>Surname: <span th:text="*{lastName}">Pepper</span>.</p>
<p>Nationality: <span th:text={nationality}">Saturn</span>.</p>
</div>
等价于
<div>
<p>Name: <span th:text="${session.user.firstName}">Sebastian</span>.</p>
<p>Surname: <span th:text="${session.user.lastName}">Pepper</span>.</p>
<p>Nationality: <span th:text="${session.user.nationality}">Saturn</span>.</p>
</div>

还有一种方式
<div>
<p>Name: <span th:text="*{session.user.name}">Sebastian</span>.</p>
<p>Surname: <span th:text="*{session.user.surname}">Pepper</span>.</p>
<p>Nationality: <span th:text="*{session.user.nationality}">Saturn</span>.</p>
