2、错误原因

In a macro declaration, parameters without a default value must all occur before the parameters with default values.

在宏定义时，缺省参数要放到非缺省值前

错误做法：

<#macro select value="" id datas>     <select id="${id}" name="${id}">          <option>---请选择---</option>          <#list datas as data>              <option value="${data}">${data}</option>          </#list>     </select></#macro>

3、解决办法

正确做法：

<#macro select id datas value="">     <select id="${id}" name="${id}">          <option>---请选择---</option>          <#list datas as data>              <#if value == data>                 <option value="${data}" selected>${data}</option>                 <#else>                 <option value="${data}">${data}</option>              </#if>          </#list>     </select></#macro>
