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>

6. list标签遍历map： 

<#list avertisementTypeMap?keys as key>
    <option value="${key}">${avertisementTypeMap[key]}</option>
</#list>
