不知道那个地方配置错了,或者其它问题,date.format被原样输出
以下是我的主要的两个配置文件源代码,
整个练习的数据库脚本(注:mysql数据库),以及所有源代码在附件当中,由于jar包占的内存太大,所有jar包都是空,只是一个1kb空jar包

		End
		
		Multiple Property Sort
		#foreach($obj in $sorter.sort($objects, ["name", "ordinal"]))
		$obj.name, $obj.ordinal
		#end
		End
		By default the sort tool sorts ascending, you can override this by adding a sort type suffix to any property name.
		
		The supported suffixes are: 
		
		For ascending
		:asc
		For descending
		:desc
		
		Example
		#foreach($obj in $sorter.sort($objects, ["name:asc", "ordinal:desc"]))
		$obj.name, $obj.ordinal
		#end
		
		This will sort first by Name in ascending order and then by Ordinal in descending order, of course you could have left the :asc off of the 'Name' property as ascending is always the default.
