2、错误原因

<#--freemarker自定义标签-->
     <#--对于write自定义标签有两个参数，nums是次数，name是名称-->
	 <#macro write nums name>
	     <#list 1..nums as num>
	                   姓名：张三丰
	                   性别：男
	     </#list>
	 </#macro>

	 <@write/>

由于write自定义标签有两个参数，在调用它的时候需要给两个参数指定值，否则报错

3、解决办法

<@write nums=4 name="你好！"/>

给两个参数赋值
