freemarker截取字符串

<#list list1 as list>

<#if (list.title?length>15)>
${list.title[0..15]?default("")}
<#else>
${list.title?default("")}
</#if>
</#list>

如果实际长度没有13那么长的话加多个if

Template Author's Guide/Expressions.

You can nest if directives (of course):

	<#if x == 1> x is 1 <#if y == 1> and y is 1 too <#else> but y is not </#if> <#else> x is not 1 <#if y < 0> and y is less than 0 </#if> </#if>

Note

How to test if x is greater than 1? <#if x > 1> will be wrong, as FreeMarker will interpret the first > as the end of the tag. Thus, either write <#if (x > 1)> or <#if x &gt; 1>.
