Spring整合的quartz任务调度的实现方式
一、在web.xml中将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>contextConfigLocationparam-name>
<param-value>/WEB-INF/classes/beans.xmlparam-value>
context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
listener-class>
listener>
web-app>
二、导入相关的jar包
三、编写相关的类文件
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
* 创建人 ：涂作权
* 日期时间： 2013-6-18下午02:09:20
* 描述 ： 创建一个要执行任务的类，该类必须继承QuartzJobBean规范
* 版本号 ： V1.0
*/
publicclass CodeCurDate extends QuartzJobBean {
/**
* 以某个时间段为周期，循环执行的方法
* 到大某个时间，要执行的方法
*/
protectedvoidexecuteInternal(JobExecutionContextarg0)
throws JobExecutionException {
System.out.println("ppppppppppppppppppppppppppppppppp");
System.out.println(new Date());
}
}
四、编写相关的配置文件
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">
<beanid="codeCurDate"class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass">
<value>cn.itcast.CodeCurDatevalue>
property>
bean>
<beanid="codeCurDateTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
<property name="jobDetail"ref="codeCurDate">property>
<property name="startDelay"value="2000"/>
<property name="repeatInterval"value="4000"/>
bean>
<beanclass="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<refbean="codeCurDateTrigger"/>
list>
property>
bean>
beans>
五、启动服务器，接着就可以看到控制台中每隔一段时间就与输出。
二、通过CronTrigerBean的方式实现的任务调度策略
首先：编写任务执行类
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
*创建人 ：涂作权
*日期时间：2013-6-18 下午02:54:57
*描述 ：
*版本号 ：V1.0
*/
public class CodeCurDate extendsQuartzJobBean {
/**
* 以某个时间段为周期，循环执行的方法
* 到大某个时间，要执行的方法
*/
protectedvoid executeInternal(JobExecutionContext arg0)
throwsJobExecutionException {
System.out.println("PPPPPPPPPPPPPPPPPPPPPPPP");
System.out.println(newDate());
}
}
其次:在Spring的配置文件进行配置，配置代码如下：
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">
<beanid="codeCurDate"class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="jobClass">
<value>cn.itcast.CodeCurDatevalue>
property>
bean>
<beanid="codeCurDateTrigger"class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail"ref="codeCurDate"/>
<property name="cronExpression"value="0 32 13 * * ?"/>
bean>
<beanclass="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<refbean="codeCurDateTrigger"/>
list>
property>
bean>
beans>
最后：在web.xml中配置相关数据
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>contextConfigLocationparam-name>
<param-value>/WEB-INF/classes/beans.xmlparam-value>
context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
listener>
web-app>
