freemarker list (长度,遍历,上标,嵌套,排序)

freemarker list (长度,遍历,下标,嵌套,排序) 1. freemarker获取list的size：

Java ArrayList<String> list = new ArrayList<String>(); 

Freemaker ${list?size} 

2.list的遍历： <#list animals as being>

    <tr> 

        <td>${being.name}${being.price}<td>

    </tr>

</#list> 

3.list

遍历中的下标序号：_index是list的一个属性 <#list list as a>

     ${a_index}

</#list>  

4. list的嵌套：

 <#list jsskList as jsskVO>

   <#list kcList as kcVO> 

    <#if kcVO.kch=jsskVO.kch>

（

     kcVO里有编号和名称，而jsskVO里只有编号）      ${kcVO.kcm} 

    </#if>

   </#list>

</#list> 

5. list排序： 升序.sort_by()

<#list list?sort_by("字段") as x>

</#list> 

降序.sort_by()?reverse <#list list?sort_by("字段")?reverse as x> 

</#list>
