Quartz（三）整合spring

1.spring XML配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
	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-4.0.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
	http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">

	<!-- 定义任务bean -->
	<bean name="myJobDetail"
		class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
		<!-- 指定具体的job类 -->
		<property name="jobClass" value="cn.itcast.quartz.MyJob" />
		<!-- 指定job的名称 -->
		<property name="name" value="myJob" />
		<!-- 指定job的分组 -->
		<property name="group" value="jobs" />
		<!-- 必须设置为true，如果为false，当没有活动的触发器与之关联时会在调度器中删除该任务 -->
		<property name="durability" value="true" />
		<!-- 指定spring容器的key，如果不设定在job中的jobmap中是获取不到spring容器的 -->
		<property name="applicationContextJobDataKey" value="applicationContext" />
	</bean>

	<!-- 定义触发器 -->
	<bean id="cronTrigger"
		class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
		<property name="jobDetail" ref="myJobDetail" />
		<!-- 每隔5秒钟执行一次 -->
		<property name="cronExpression" value="0/5 * * * * ?" />
	</bean>

	<!-- 定义触发器 -->
	<!-- 演示：一个job可以有多个trigger； -->
	<bean id="cronTrigger2"
		class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
		<property name="jobDetail" ref="myJobDetail" />
		<!-- 每一分钟执行一次 -->
		<property name="cronExpression" value="0/8 * * * * ?" />
	</bean>

	<!-- 定义调度器 -->
	<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="cronTrigger" />
				<ref bean="cronTrigger2" />
			</list>
		</property>
	</bean>

</beans>

2.定义JOB

package cn.itcast.quartz;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;

/**
 * 定义要执行的JOB
 */
public class MyJob extends QuartzJobBean {
    
    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        System.out.println("myJob 执行了............." + context.getTrigger().getKey().getName());
        ApplicationContext applicationContext = (ApplicationContext) context.getJobDetail().getJobDataMap()
                .get("applicationContext");
        System.out.println("获取到的Spring容器是： " + applicationContext);
        
    }

}

3.启动Quartz调度

package cn.itcast.quartz;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {
	
	public static void main(String[] args) {
		new ClassPathXmlApplicationContext("classpath:applicationContext-scheduler.xml");
	}

}
