2、错误原因
/**
* freemarker基本数据类型
* @Title:testDataType
* @Description:
* @param:
* @return: void
* @throws
*/
@Test
public void testDataType()
{
root.put("nowsday", new Date());
studentPrint("type.ftl");
}
${nowsday}
不能将日期类型直接转换为字符串，因为不知道是日期类型中的哪一种在使用，是date、time还是datetime。并且不知道转换成字符串日期到底显示成什么格式，是yyyy-MM-dd，还是HH:mm:ss，还是yyyy-MM-dd HH:mm:ss
3、解决办法
<#--日期类型-->
${nowsday?string("yyyy-MM-dd")}
结果：2014-05-31
