    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)
