!${#maps.isEmpty()} ： map不为空

3.list

<tr th:class="${#lists.isEmpty(examPaper['courseList'])} ? '':'hide'"></tr>
<span th:if="!${#lists.isEmpty(course['teacherList'])} and ${#lists.size(course['teacherList'])}>4" ></span>

th:class class样式

</section>

<span class="fs18" th:text="${#strings.concat('班级名称：', classes['name'])}"></span>

<samp th:text="${#strings.substring(details['createTime'],0,16)}"></samp>

${#strings.isEmpty()} string为空

${#strings.concat(‘’,’’) 拼接

${#strings.contains()} : 包含某字符

${#strings.substring(‘’, ,) string截取字符串

5.date

<div class="pull-right">&copy;<span th:text="'2010-'+${#dates.format(new java.util.Date().getTime(), 'yyyy')}"></span></div>

动态id

th:data-id="${examQuestionRecord['id']}+'-'+${subIndex.count}"

唯一动态id

th:attr="data-id=${personalTask['examPaper']['id']},data-time=${#strings.substring(personalTask['examPaper']['endTime'],0,16)},data-url=${personalTask['examPaper']['datumList'][0]['url']}"
