本文通过几个示例展示了Freemarker模板引擎的基本用法，包括非空判断、字符串长度判断及截取、集合非空判断及遍历等常见场景。

1.if-非空判断

<#if (list.startDate)??>
	${list.startDate.toString().substring(0,10)}
</#if>


2.if-else-字符窜长度判定以及截取<#if (nlist.nabstract?length > 85)> 
	${nlist.nabstract?substring(0,85)}...
<#else> 
	${nlist.nabstract}
</#if>

<a href="${Constants.web_5p}">

3.if-else-集合非空判断-便利-截取-取值
<#if (noticeList)?? && (noticeList?size > 0)>
	<#list noticeList as list>
		<div class="noteNlist">
			<a href="noticedeatil-${list.id}.html" title="${list.ntitle}">${list.ntitle}</a>
		</div>
		<div class="noteNlist">
		  <a href="noticedeatil-${list.id}.html" title="${list.ntitle}" target="_blank">
				<#if (list.ntitle?length > 19)> 
					${list.ntitle?substring(0,18)}...
				<#else> 
					${list.ntitle}
				</#if>
		  </a>
		</div>
	</#list>
<#else>
	<div class="noteNlist">暂无相应公告信息！</div>
</#if>


4.区间值的便利以及判断
<#if pagination.pageNo != 1><li class="nextPage">
	<a href="javascript:fytj('${pagination.pageNo-1}');">上一页</a></li>
</#if>
<#list pagination.onepage..pagination.lstpage as pi>
	<#if pagination.pageNo?eval == pi>
		<li class="pagNum"><a href="javascript:fytj('${pi}');">${pi}</a></li>
	<#else>
		<li class="pagNum"><a href="javascript:fytj('${pi}');">${pi}</a></li>
	</#if>
</#list>
<#if pagination.pageNo != pagination.totalPage>
	<li class="nextPage"><a href="javascript:fytj('${pagination.pageNo+1}');">下一页</a></li>
</#if>

<#list pagination.onepage..pagination.lstpage as pi>
	<#if pagination.pageNo?eval == pi>
		<li class="pagNumOn"><a href="javascript:fytj('${pi}');">${pi}</a></li>
	<#else>
		<li class="pagNum"><a href="javascript:fytj('${pi}');">${pi}</a></li>
	</#if>
</#list>
