Quartz.Net小知识两则
1 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 xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0" overwrite-existing-jobs="true"> <job> <job-detail> <name>CaiJiJob</name> <group>jobGroup1</group> <job-type>WAT.PMS.JOB.Job.CaiJiJob, WAT.PMS.JOB</job-type> </job-detail> <trigger> <simple> <name>simpleName</name> <group>simpleGroup</group> <description>SimpleTriggerDescription</description> <job-name>jobName1</job-name> <job-group>jobGroup1</job-group> <start-time>1982-06-28T18:15:00.0Z</start-time> <repeat-count>0</repeat-count> </simple> </trigger> </job> <job> <job-detail> <name>SavaDataJob</name> <group>jobGroup2</group> <job-type>WAT.PMS.JOB.Job.SaveDataJob, WAT.PMS.JOB</job-type> </job-detail> <trigger> <cron> <name>cronName2</name> <group>cronGroup2</group> <job-name>jobName2</job-name> <job-group>jobGroup2</job-group> <start-time>1982-06-28T18:15:00+02:00</start-time> <cron-expression>0 0/2 * * * ?</cron-expression> </cron> </trigger> </job></quartz>
2 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；CW#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)
