Quartz.net配置文件实例及cron表达式详解
- 从XML文件创建作业
最新版本的quartz.net支持直接从xml文件创建作业,使用起来很方便.配置文件的格式可以参考下面的例子
<?xml?version="1.0"?encoding="UTF-8"?>

</quartz> - Cron表达式知识
"Cron-Expression"由6到7个用空格分开的字段组成的表达式这6或7个字段必须遵循下面的顺序和格式:
Seconds 0-59 , - * /
Minutes 0-59 ,- * /
Hours 0-23 , - * /
Day-of-month 1-31 , - * ? / L W C
Month 1-12 or JAN-DEC , - * /
Day-of-Week 1-7 or SUN-SAT , - * ? / L C #
Year (Optional) empty, 1970-2099 , - * /
*是一个通配符,表示任何值,用在Minutes字段中表示每分钟。
?只可以用在day-of-month或者Day-of-Week字段中,用来表示不指定特殊的值。
-用来表示一个范围,比如10-12用在Month中表示10到12月。
,用来表示附加的值,比如MON,WED,FRI在day-of-week字段中表示礼拜一和礼拜三和礼拜五。
/用来表示增量,比如0/15用在Minutes字段中表示从0分开始0和15和30和45分。
L只可以用在day-of-month或者Day-of-Week字段中,如果用在Day-of-month中,表示某个月的最后一天,1月则是表示31 号,2月则表示28号(非闰年),如果用在Day-of-Week中表示礼拜六(数字7);但是如果L与数字组合在一起用在Day-of-month中, 比如6L,则表示某个月的最后一个礼拜六;?
0 1 0 1 1-12 ?表示每月1号0点1分执行。
0 0 21 ? * 1表示每个礼拜天 21点0分执行。
0 0 0 * * ?表示每天0点0分执行。
0 * 22 * * ?表示每天22点开始每分钟
0 * 0-23 * * ?表示每天每分钟(0 * * * * ? 不可以???Doltter注释)?
