我有一段代码：

<div class="col-md-3 col-sm-6 text-center">
<a href="/" class="logo logo_image">
    <span>
        <block >Plats</block>
        <span class="muellerhoff" >Bruts</span>
    </span>
    <img src="http://172.114.143.253:7080/images/logo.png" >
</a>
</div>

我在浏览器上看到：

但当我使用胸腺素时：

<div class="col-md-3 col-sm-6 text-center">
    <a href="/" class="logo logo_image">
        <th:block th:text="${@environment.getProperty('site.name1')}" />
        <span class="muellerhoff" th:text="${@environment.getProperty('site.name2')}"></span>
        <img th:src="@{/images/logo.png}" th:alt="${@environment.getProperty('site.name')}"  th:title="{@environment.getProperty('site.name')}">
    </a>
</div>

样式丢失：

当我查看源代码时，我看到：

<div class="col-md-3 col-sm-6 text-center">
                            <a href="/" class="logo logo_image">
                                Plats
                                <span class="muellerhoff">Bruts</span>
                                <img th:src="@{/images/logo.png}" th:alt="${@environment.getProperty('site.name')}"  th:title="{@environment.getProperty('site.name')}">
                            </a>
                        </div>

我也试过了 <block th:text="${@environment.getProperty('site.name1')}" /> 同样的结果
