spring2.0 quartz 靜態定時任務

1.配置簡單的spring 定時任務

 

配置檔案中定義一個schedule的Factory

 

<bean id="scheduler"
		class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref local="triggerJobTester" />
			</list>
		</property>
	</bean>

 這個schedule工廠bean會隨著容器啟動而啟動.然後定義一個定時執行的規則.

<!-- 描述了一個定時處理的機制 -->
<bean id="triggerJobTester"
		class="org.springframework.scheduling.quartz.SimpleTriggerBean"
		p:jobDetail-ref="jobDetailTesterTarget" p:startDelay="1000"
		p:repeatInterval="2000">
	</bean>
<!-- 指定定時器要定時執行的類和方法 -->
<bean id="jobDetailTesterTarget"
		class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"
		p:targetObject-ref="scheduleTarget" p:targetMethod="testMethod">
	</bean>
<!-- 在sping當中註冊定時器的FactoryBean -->
	<bean id="scheduleTarget"
		class="com.lsk.spring.schedule.ScheduleTarget" />

 p:startDelay 指定容器啟動後多少毫秒開始執行定時方法.
p:repeatInterval 指定隔多少毫秒再一次的執行定時方法.

2.配置特定時間的任務 。

 

<!-- 指定定時器要定時執行的類和方法 -->
<bean id="schedulerJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> 
        <property name="targetObject" ref="scheduleInfoAction"/> 
        <property name="targetMethod" value="simpleJobTest"/> 
        <property name="concurrent" value="false"/> 
 </bean> 
    

<!-- 描述了一個定時處理的機制 -->
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean" > 
         <property name="jobDetail" ref="schedulerJobDetail"/> 
         <property name="cronExpression"> 
             <value>0/10 * * * * ?</value> 
         </property> 
     </bean> 

  配置檔案中定義一個schedule的Factory         

 <bean id="schedulerFactory" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> 
        <property name="triggers"> 
            <list> 
                <ref local="cronTrigger"/> 
            </list> 
        </property> 
</bean> 

scheduleInfoAction 需要自己定義 ，並寫個void 無參的方法

在上面的配置中設定了

① targetMethod: 指定需要定時執行scheduleInfoAction中的simpleJobTest()方法

② concurrent：對於相同的JobDetail，當指定多個Trigger時, 很可能第一個job完成之前，第二個job就開始了。指定concurrent設為false，多個job不會併發執行，第二個job將不會在第一個job完成之前開始。

③ cronExpression：0/10 * * * * ?表示每10秒執行一次，具體可參考附表。

④ triggers：通過再新增其他的ref元素可在list中放置多個觸發器。

 

scheduleInfoAction 中的simpleJobTest()方法

注意：此方法沒有引數，如果scheduleInfoAction有兩個方法simpleJobTest()和simpleJobTest(String argument)，則spring只會去執行無參的simpleJobTest().

public void simpleJobTest() { 

        log.warn("uh oh, Job is scheduled !'" + "' Success...");

    }

 

//下面具體描述 特定時間配置  cronExpression 的value設定

 

欄位 	  	允許值 	  	允許的特殊字元
秒 	  	0-59 	  	, - * /
分 	  	0-59 	  	, - * /
小時 	  	0-23 	  	, - * /
日期 	  	1-31 	  	, - * ? / L W C
月份 	  	1-12 或者 JAN-DEC 	  	, - * /
星期 	  	1-7 或者 SUN-SAT 	  	, - * ? / L C #
年（可選） 	  	留空, 1970-2099 	  	, - * /

 The '*' character is used to specify all values. For example, "*" in the minute field means "every minute".
“*”字元被用來指定所有的值。如：”*“在分鐘的欄位域裡表示“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.
“?”字元只在日期域和星期域中使用。它被用來指定“非明確的值”。當你需要通過在這兩個域中的一個來指定一些東西的時候，它是有用的。看下面的例子你就會明白。
月份中的日期和星期中的日期這兩個元素時互斥的一起應該通過設定一個問號(?)來表明不想設定那個欄位

The '-' character is used to specify ranges For example "10-12" in the hour field means "the hours 10, 11 and 12".
“-”字元被用來指定一個範圍。如：“10-12”在小時域意味著“10點、11點、12點”。

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".
“,”字元被用來指定另外的值。如：“MON,WED,FRI”在星期域裡表示”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.

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’的省略寫法可以表示day-of-month和day-of-week域，但在兩個欄位中的意思不同，例如day-of-month域中表示一個月的最後一天，
如果在day-of-week域表示‘7’或者‘SAT’，如果在day-of-week域中前面加上數字，它表示一個月的最後幾天，例如‘6L’就表示一個月的最後一個
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".
