首先，如果你在web.xml文件中的配置是这样的：

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

那么需要在工程下创建一个以applicationContext- 为开头的xml文件eg:applicationContext-jobconfig.xml

xml的头和结尾部分跟其他spring配置文件相似，就不赘述，正文如下：

 <bean id="youJobName(类别名)" class="com.******.YourJobClassLocation(类的定位)" />
 <bean id="doYourJob(别名)" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
     <property name="targetObject">
      <ref bean="youJobName(类别名)""/>
     </property>
     <property name="targetMethod">
      <value>runMethodName(定时执行的方法名)</value>
     </property>
 </bean>
 
 <bean id="youJobNameTrigger(触发器别名)" class="org.springframework.scheduling.quartz.CronTriggerBean">
   <property name="jobDetail">
     <ref bean="doYourJob(别名)""/>
   </property>
   <property name="cronExpression">
    <value>0 0/20 * * * ?(定时的时间配置)</value>
   </property>
 </bean>

 <bean id="doScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
   <property name="triggers">
     <list>
      <ref local="youJobNameTrigger(触发器别名)"/>  
     </list>
   </property>
 </bean>

这样的配置几本就可以运转了，但是有一个地方可能是你需要根据你的需求来确定的，那就是触发时间。

下面有一些关于时间配置的说明：

The '*' character is used to specify all values. For example, "*" in the minute field means "every minute".
“*”字符被用来指定所有的值。如：”*“在分钟的字段域里表示“每分钟”。
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。它被用来指定“非明确的值”。当你需要通过在这两个域中的一个来指定一些东西的时候，它是有用的。看下面的例子你就会明白。
月份中的日期和星期中的日期这两个元素时互斥的一起应该通过设置一个问号(?)来表明不想设置那个字段

The '-' character is used to specify ranges For example "10-12" in the hour field means "the hours 10, 11 and 12".
“-”字符被用来指定一个范围。如：“10-12”在小时域意味着“10点、11点、12点”。

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".
“,”字符被用来指定另外的值。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.

"/"字符用来指定渐增的值。例如0/15出现在秒字段的时候意味着“在第0，15，30和45秒”（的时候被触发）。而5/15出现在秒字段的时候意味着“在第5，20，35和第50秒”（的时候被触发）。"*/"和"0/"的指定是等价的。

注：当分子+分母的值大于该字段的最大值，如在秒钟字段出现45/20的时候，表示在第45秒以后的每20会触发一次，但是20秒以后又算做另外的时间段以内了，所以该字段的/20即失效，如改为45/10 则只有第45 和55秒会执行一次。

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是‘last’的省略写法可以表示day-of-month和day-of-week域，但在两个字段中的意思不同，例如day-of-month域中表示一个月的最后一天，
如果在day-of-week域表示‘7’或者‘SAT’，如果在day-of-week域中前面加上数字，它表示一个月的最后几天，例如‘6L’就表示一个月的最后一个
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".
