          首先,如果你在web.xml文件中的配置是這樣的:

            <context-param>
                  <param-name>contextConfigLocation</param-name>
                  <param-value>
                   /WEB-INF/classes/applicationContext-*.xml
                  </param-value>
           </context-param>

          那么需要在工程下創(chuàng)建一個(gè)以applicationContext- 為開頭的xml文件eg:applicationContext-jobconfig.xml

          xml的頭和結(jié)尾部分跟其他spring配置文件相似,就不贅述,正文如下:

           <bean id="youJobName(類別名)" class="com.******.YourJobClassLocation(類的定位)" />
           <bean id="doYourJob(
          別名)" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
               <property name="targetObject">
                <ref bean="youJobName(
          類別名)""/>
               </property>
               <property name="targetMethod">
                <value>runMethodName(
          定時(shí)執(zhí)行的方法名)</value>
               </property>
           </bean>
           
           <bean id="youJobNameTrigger(
          觸發(fā)器別名)" class="org.springframework.scheduling.quartz.CronTriggerBean">
             <property name="jobDetail">
               <ref bean="doYourJob(
          別名)""/>
             </property>
             <property name="cronExpression">
              <value>0 0/20 * * * ?(
          定時(shí)的時(shí)間配置)</value>
             </property>
           </bean>

           <bean id="doScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
             <property name="triggers">
               <list>
                <ref local="youJobNameTrigger(
          觸發(fā)器別名)"/>  
               </list>
             </property>
           </bean>

          這樣的配置幾本就可以運(yùn)轉(zhuǎn)了,但是有一個(gè)地方可能是你需要根據(jù)你的需求來(lái)確定的,那就是觸發(fā)時(shí)間。

          下面有一些關(guān)于時(shí)間配置的說(shuō)明:

          字段順序

           

          允許值

           

          允許的特殊字符

          留空, 1970-2099

          , - * /


          The '*' character is used to specify all values. For example, "*" in the minute field means "every minute".
          “*”
          字符被用來(lái)指定所有的值。如:”*“在分鐘的字段域里表示每分鐘。
          The '?' character is allowed for the day-of-month and day-of-week fields. It is used to specify 'no specific value'. This is useful when you need to specify something in one of the two fileds, but not the other. See the examples below for clarification.
          “?”
          字符只在日期域和星期域中使用。它被用來(lái)指定非明確的值。當(dāng)你需要通過(guò)在這兩個(gè)域中的一個(gè)來(lái)指定一些東西的時(shí)候,它是有用的。看下面的例子你就會(huì)明白。
          月份中的日期和星期中的日期這兩個(gè)元素時(shí)互斥的一起應(yīng)該通過(guò)設(shè)置一個(gè)問(wèn)號(hào)(?)來(lái)表明不想設(shè)置那個(gè)字段

          The '-' character is used to specify ranges For example "10-12" in the hour field means "the hours 10, 11 and 12".
          “-”
          字符被用來(lái)指定一個(gè)范圍。如:“10-12”在小時(shí)域意味著“10點(diǎn)、11點(diǎn)、12點(diǎn)。

          The ',' character is used to specify additional values. For example "MON,WED,FRI" in the day-of-week field means "the days Monday, Wednesday, and Friday".
          “,”
          字符被用來(lái)指定另外的值。如:“MON,WED,FRI”在星期域里表示星期一、星期三、星期五”.

          The '/' character is used to specify increments. For example "0/15" in the seconds field means "the seconds 0, 15, 30, and 45". And "5/15" in the seconds field means "the seconds 5, 20, 35, and 50". Specifying '*' before the '/' is equivalent to specifying 0 is the value to start with. Essentially, for each field in the expression, there is a set of numbers that can be turned on or off. For seconds and minutes, the numbers range from 0 to 59. For hours 0 to 23, for days of the month 0 to 31, and for months 1 to 12. The "/" character simply helps you turn on every "nth" value in the given set. Thus "7/6" in the month field only turns on month "7", it does NOT mean every 6th month, please note that subtlety.

          "/"字符用來(lái)指定漸增的值。例如0/15出現(xiàn)在秒字段的時(shí)候意味著在第0,15,3045(的時(shí)候被觸發(fā))。而5/15出現(xiàn)在秒字段的時(shí)候意味著在第5,2035和第50(的時(shí)候被觸發(fā))。"*/""0/"的指定是等價(jià)的。

          注:當(dāng)分子+分母的值大于該字段的最大值,如在秒鐘字段出現(xiàn)45/20的時(shí)候,表示在第45秒以后的每20會(huì)觸發(fā)一次,但是20秒以后又算做另外的時(shí)間段以內(nèi)了,所以該字段的/20即失效,如改為45/10 則只有45 55秒會(huì)執(zhí)行一次。

          The 'L' character is allowed for the day-of-month and day-of-week fields. This character is short-hand for "last", but it has different meaning in each of the two fields. For example, the value "L" in the day-of-month field means "the last day of the month" - day 31 for January, day 28 for February on non-leap years. If used in the day-of-week field by itself, it simply means "7" or "SAT". But if used in the day-of-week field after another value, it means "the last xxx day of the month" - for example "6L" means "the last friday of the month". When using the 'L' option, it is important not to specify lists, or ranges of values, as you'll get confusing results.

          L
          ‘last’的省略寫法可以表示day-of-monthday-of-week域,但在兩個(gè)字段中的意思不同,例如day-of-month域中表示一個(gè)月的最后一天,
          如果在day-of-week域表示‘7’或者‘SAT’,如果在day-of-week域中前面加上數(shù)字,它表示一個(gè)月的最后幾天,例如‘6L’就表示一個(gè)月的最后一個(gè)
          星期五,

          The 'W' character is allowed for the day-of-month field. This character is used to specify the weekday (Monday-Friday) nearest the given day. As an example, if you were to specify "15W" as the value for the day-of-month field, the meaning is: "the nearest weekday to the 15th of the month". So if the 15th is a Saturday, the trigger will fire on Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th. However if you specify "1W" as the value for day-of-month, and the 1st is a Saturday, the trigger will fire on Monday the 3rd, as it will not 'jump' over the boundary of a month's days. The 'W' character can only be specified when the day-of-month is a single day, not a range or list of days
          .
          The 'L' and 'W' characters can also be combined for the day-of-month expression to yield 'LW', which translates to "last weekday of the month".

          The '#' character is allowed for the day-of-week field. This character is used to specify "the nth" XXX day of the month. For example, the value of "6#3" in the day-of-week field means the third Friday of the month (day 6 = Friday and "#3" = the 3rd one in the month). Other examples: "2#1" = the first Monday of the month and "4#5" = the fifth Wednesday of the month. Note that if you specify "#5" and there is not 5 of the given day-of-week in the month, then no firing will occur that month.

          The 'C' character is allowed for the day-of-month and day-of-week fields. This character is short-hand for "calendar". This means values are calculated against the associated calendar, if any. If no calendar is associated, then it is equivalent to having an all-inclusive calendar. A value of "5C" in the day-of-month field means "the first day included by the calendar on or after the 5th". A value of "1C" in the day-of-week field means "the first day included by the calendar on or after sunday".
