Quartz.net配置文件实例及cron表达式详解

  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;

    ?

    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)
