胸腺th：塊不再起作用

Question

我在Thymeleaf寫了一段代碼：

<th:block th:if="${i.mid} > ${yesterday.tableRateModel.rates[e.index].mid}">
                        <i class="glyphicon glyphicon-arrow-up"></i>
                    </th:block>
                    <th:block th:if="${i.mid} == ${yesterday.tableRateModel.rates[e.index].mid}">
                        <i class="glyphicon glyphicon-resize-small"></i>
                    </th:block>
                    <th:block th:if="${i.mid} < ${yesterday.tableRateModel.rates[e.index].mid}">
                        <i class="glyphicon glyphicon-arrow-down"></i>
                    </th:block>

在這種情況下，我得到如下錯誤： org.xml.sax.SAXParseException: The value of attribute "th:if" associated with an element type "th:block" must not contain the '<' character.

但是，當我評論最后一個th:block一切正常。 怎么了？

問題出在<

Answer 1

用這個：

&lt; for <
&gt; for >
&le; for <=
&ge; for >=
