一、在web.xml中將配置文件的位置指定好。

Web.xml的配置如下：

<?xmlversion="1.0"encoding="UTF-8"?>

<web-appversion="2.5"

????? xmlns="http://java.sun.com/xml/ns/javaee"

????? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

????? xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

????? http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

???

<context-param>

????? <param-name>contextConfigLocation</param-name>

????? <param-value>/WEB-INF/classes/beans.xml</param-value>

??? </context-param>

<listener>?

<listener-class>

org.springframework.web.context.ContextLoaderListener

????? ? ??</listener-class>

????? </listener>

</web-app>

二、導入相關的jar包

三、編寫相關的類文件

package cn.itcast;

?

import java.util.Date;

?

import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

import org.springframework.scheduling.quartz.QuartzJobBean;

/**

?* 文件名????: CodeCurDate.java<br/>

?* 創建人????：涂作權<br/>

?* 日期時間： 2013-6-18下午02:09:20<br/>

?* 描述??????????：?創建一個要執行任務的類，該類必須繼承QuartzJobBean規范<br/>

?* 版本號????： V1.0

?*/

publicclass CodeCurDate extends QuartzJobBean {

?

????? /**

????? ?* 以某個時間段為周期，循環執行的方法

????? ?* 到大某個時間，要執行的方法

????? ?*/

????? protectedvoidexecuteInternal(JobExecutionContextarg0)

???????????????????????? throws JobExecutionException {

?????????????? System.out.println("ppppppppppppppppppppppppppppppppp");

?????????????? System.out.println(new Date());

????? }

}

四、編寫相關的配置文件

<?xmlversion="1.0"encoding="UTF-8"?>

<beans?xmlns="http://www.springframework.org/schema/beans"

??????? xmlns:context="http://www.springframework.org/schema/context"

??????? xmlns:aop="http://www.springframework.org/schema/aop"

??????? xmlns:tx="http://www.springframework.org/schema/tx"

?????????????? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

?????????????? xsi:schemaLocation="http://www.springframework.org/schema/beans

?????????????? ??????? ????????????http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

?????????????? ???????????????????http://www.springframework.org/schema/context

?????????????? ???????????????????http://www.springframework.org/schema/context/spring-context-2.5.xsd

?????????????? ???????????????? ???http://www.springframework.org/schema/tx

?????????????? ???????????????????http://www.springframework.org/schema/tx/spring-tx-2.5.xsd

?????????????? ???????????????????http://www.springframework.org/schema/aop

?????????????? ???????????????????http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">

?????????????? ???????????????????

????? <!-- 1創建執行任務的類的實例 -->

????? <beanid="codeCurDate"class="org.springframework.scheduling.quartz.JobDetailBean">

????? ?? <!--在spring中執行任務的類的實例的創建,不是通過spring的普通的方法,而是把融合到其他JobDetailBean類中-->

????? ?? <property name="jobClass">

????? ????<value>cn.itcast.CodeCurDate</value>

????? ?? </property>

????? </bean>

?????

????? <!-- 2創建一個觸發器,整合執行任務的類的實例和時間關聯 -->

????? <beanid="codeCurDateTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">

????? ? <!-- 注入要執行任務的類的實例 -->

????? ? <property name="jobDetail"ref="codeCurDate"></property>

????? ? <!-- 配置該觸發器,在第一次啟動之前等待2秒,以毫秒為單位 -->

????? ? <property name="startDelay"value="2000"/>

????? ? <!--配置啟動后,每隔4秒執行任務一次,以毫秒為單位-->

????? ? <property name="repeatInterval"value="4000"/>

????? </bean>

?????

????? <!-- 3注冊觸發器,啟動調度任務 -->

????? <beanclass="org.springframework.scheduling.quartz.SchedulerFactoryBean">

????? ??? <property name="triggers">

????? ??????<list>

????? ?????????<refbean="codeCurDateTrigger"/>

????? ??????</list>

????? ??? </property>

????? </bean>

</beans>

五、啟動服務器，接著就可以看到控制臺中每隔一段時間就與輸出。

?

?

二、通過CronTrigerBean的方式實現的任務調度策略

首先：編寫任務執行類

package cn.itcast;

?

import java.util.Date;

?

import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

importorg.springframework.scheduling.quartz.QuartzJobBean;

/**

?*文件名???? : CodeCurDate.java<br/>

?*創建人???? ：涂作權<br/>

?*日期時間：2013-6-18 下午02:54:57<br/>

?*描述?????????? ：? <br/>

?*版本號???? ：V1.0

?*/

public class CodeCurDate extendsQuartzJobBean {

?

????? /**

????? ?* 以某個時間段為周期，循環執行的方法

????? ?* 到大某個時間，要執行的方法

????? ?*/

????? protectedvoid executeInternal(JobExecutionContext arg0)

???????????????????????? throwsJobExecutionException {

?????????????? System.out.println("PPPPPPPPPPPPPPPPPPPPPPPP");

?????????????? System.out.println(newDate());

????? }

}

其次:在Spring的配置文件進行配置，配置代碼如下：

<?xmlversion="1.0"encoding="UTF-8"?>

<beans?xmlns="http://www.springframework.org/schema/beans"

??????? xmlns:context="http://www.springframework.org/schema/context"

??????? xmlns:aop="http://www.springframework.org/schema/aop"

??????? xmlns:tx="http://www.springframework.org/schema/tx"

?????????????? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

?????????????? xsi:schemaLocation="http://www.springframework.org/schema/beans

?????????????? ??????????????????? http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

?????????????? ???????????????????http://www.springframework.org/schema/context

?????????????? ???????????????????http://www.springframework.org/schema/context/spring-context-2.5.xsd

?????????????? ??????????????????? http://www.springframework.org/schema/tx

?????????????? ???????????????????http://www.springframework.org/schema/tx/spring-tx-2.5.xsd

?????????????? ???????????????????http://www.springframework.org/schema/aop

?????????????? ???????????????????http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">

?

????? <!-- 1創建執行任務的類的實例 -->

????? <beanid="codeCurDate"class="org.springframework.scheduling.quartz.JobDetailBean">

????? ?? <!--在spring中執行任務的類的實例的創建,不是通過spring的普通的方法,而是把融合到其他JobDetailBean類中-->

????? ?? <property name="jobClass">

????? ????<value>cn.itcast.CodeCurDate</value>

????? ?? </property>

????? </bean>

?????

????? <!-- 2創建一個觸發器,整合執行任務的類的實例和時間關聯 -->

????? <beanid="codeCurDateTrigger"class="org.springframework.scheduling.quartz.CronTriggerBean">

????? ?? <!-- 注入執行任務的類 -->

????? ?? <property name="jobDetail"ref="codeCurDate"/>

????? ?? <!-- 配置定時執行任務,9點45分將調用該觸發器的執行 -->

????? ?? <property name="cronExpression"value="0 32 13 * * ?"/>

????? </bean>

????? ?

????? <!-- 3注冊觸發器,啟動調度任務 -->

????? <beanclass="org.springframework.scheduling.quartz.SchedulerFactoryBean">

????? ??? <property name="triggers">

????? ??????<list>

????? ?????????<refbean="codeCurDateTrigger"/>

????? ??????</list>

????? ??? </property>

????? </bean>

</beans>

最后：在web.xml中配置相關數據

<?xmlversion="1.0"encoding="UTF-8"?>

<web-appversion="2.5"

????? xmlns="http://java.sun.com/xml/ns/javaee"

????? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

????? xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

????? http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

? <context-param>

? ? <param-name>contextConfigLocation</param-name>

? ? <param-value>/WEB-INF/classes/beans.xml</param-value>

? </context-param>

? <listener>

? ? <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

? </listener>

</web-app>

?
