一个cron表达式有臛_��6个（也可�?个）有空格分隔的旉��元素�?br /> 按顺序依�ơ�ؓ
1.�U�（0~59�Q?
2.分钟�Q?~59�Q?
3.��时�Q?~23�Q?
4.天（月）�Q?~31�Q�但是你需要考虑你月的天敎ͼ�

6.天（星期�Q�（1~7 1=SUN �?SUN�Q�MON�Q�TUE�Q�W(xu��)ED�Q�THU�Q�FRI�Q�SAT�Q?
7.�q�䆾�Q?970�Q?099�Q?/span>

其中每个元素可以是一个�?�?),一个连�l�区�?9-12),一个间隔时�?8-18/4)(/表示每隔4��时),一个列�?1,3,5),通配�W��?br /> �׃��"月䆾中的日期"�?星期中的日期"�q�两个元素互斥的,必须要对其中一个设�|?.

有些子表辑ּ�能包含一些范围或列表
例如�Q�子表达式（天（星期�Q�）可以�?“MON-FRI”�Q?#8220;MON�Q�W(xu��)ED�Q�FRI”�Q?#8220;MON-WED,SAT”

“*”字符代表所有可能的�?
因此�Q?#8220;*”在子表达式（月）里表�C�每个月的含义，“*”在子表达式（天（星期�Q�）表示星期的每一�?

“/”字符用来指定数值的增量
例如�Q�在子表辑ּ��Q�分钟）里的“0/15”表示从第0分钟开始，�?5分钟 ;
在子表达式（分钟�Q�里�?#8220;3/20”表示从第3分钟开始，�?0分钟�Q�它�?#8220;3�Q?3�Q?3”�Q�的含义一�?

“�Q?#8221;字符仅被用于天（月）和天�Q�星期）两个子表辑ּ��Q�表�C�Z��指定�?
�?个子表达式其中之一被指定了��g��后，��Z��避免冲突�Q�需要将另一个子表达式的��D��?#8220;�Q?#8221;

“L” 字符仅被用于天（月）和天�Q�星期）两个子表辑ּ��Q�它是单�?#8220;last”的羃�?

但是它在两个子表辑ּ�里的含义是不同的�?

在天�Q�月�Q�子表达式中�Q?#8220;L”表示一个月的最后一�?,
在天�Q�星期）自表辑ּ�中，“L”表示一个星期的最后一天，也就是SAT

如果�?#8220;L”前有具体的内容，它就��h��其他的含义了

例如�Q?#8220;6L”表示�q�个月的倒数�W�６天，“�Q�Ｒ�Q�Ｌ”表示�q�个月的最后一个星期五

注意�Q�在使用“L”参数�Ӟ��不要指定列表或范��_��因�ؓ�q�会��D��问题
