java - freemarker number_to_datetime的问题

Question

最近刚使用freemarker

数据库中存的是时间截,使用的是System.currentTimeMillis();

在freemarker模块中,使用

${user.regtime?numbertodatetime} 总是出错

Caused by: freemarker.core.NonNumericalException: For "?numbertodatetime" left-hand operand: Expected a number, but this has evaluated to a string+extended_hash (String wrapped into f.e.b.StringModel):
==> (x) [in template "WEB-INF/views

但直接这样写却能正常显示:

${x.numbertodatetime} 这样就可以
