表达式springMacroRequestContext未定义

我正在尝试使用htmlunit,junit和freemarker模板进行freemarker单元测试.但是当我使用< @ spring.message“data”>它给了我这个例外.

freemarker.core.InvalidReferenceException: Expression springMacroRequestContext is undefined on line 89, column 134 in spring.ftl.

关于这个例外的任何想法,我如何解决这个问题？提前感谢您的帮助.

解决方法:

我不确定处理这个的正确方法是什么,因为我花了大约一个小时试图弄清楚这一点.但是对我来说有用的是使用以下方法手动将“springMacroRequestContext”添加到数据模型中：

HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();
model.put("springMacroRequestContext", new RequestContext(request, null, null, null));

请注意,这仍然必须在有效请求中发生.因此,这可能不适用于cron作业或计划任务,因为当前没有请求.
