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>
