2、错误原因
在定义select组件时，给了一个name属性，但是在引用时未给name赋值，导致出错
<#import "/inc/select.ftl" as items/>
<@items.select id="city"/>
<#macro select id>
<select id="${id}" name="${name}">
<option>---请选择---</option>
</select>
</#macro>
3、解决办法
将上一段代码修改成：
<#macro select id>
<select id="${id}" name="${id}">
<option>---请选择---</option>
</select>
</#macro>
