1.UpperDirective implements TemplateDirectiveModel定义类并实现execute（）
2.jeecore-context.xml中定义bean <bean id="upper_tag" class="com.jeecms.common.web.freemarker.UpperDirective"/>
3.jeecms.properties中定义directive.uppertag=upper_tag
4.在首页index.html定义[@upper_tag]dddddd[/@upper_tag]
出现Error executing FreeMarker template
以下是错误详情
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
17:06:07.030 ERROR freemarker.runtime - Error executing FreeMarker template
freemarker.core.InvalidReferenceException: The following has evaluated to null or missing:

Tip: If the failing expression is known to be legally null/missing, either specify a default value with myOptionalVar!myDefault, or use [#if myOptionalVar??]when-present[#else]when-missing[/#if]. (These only cover the last step of the expression; to cover the whole expression, use parenthessis: (myOptionVar.foo)!myDefault, (myOptionVar.foo)??
