在生成html文件时报的异常:
freemarker.core.NonBooleanException: Error on line 21, column 22 in hello.ftl Expecting a boolean (true/false) expression here Expression student.age does not evaluate to true/false
ftl文件的代码:
<#if student.age>18>
好家伙, ${student.age} 成年啦
</#if>
------------解决方法有两个:
方法一: 把<#if student.age>18> 改为<#if 18<student.age> 貌似是把大于号当做标签的">"来看了
方法二: <#if student.age>18>中间的条件用小括号括起来,只要保证小括号里面返回true/false就行(其他的多条件判断也可以用) --------------这个很保险!
