Spring是一个很优秀的框架,它无缝的集成了Quartz,简单方便的让企业级应用更好的使用Quartz进行任务的调度。下面就对Spring集成Quartz进行简单的介绍和示例讲解!和上一节 Quartz学习——2、简单入门示例Demo
的流程相似,介绍Spring和Quartz集成存储方式使用的是RAM方式和JDBC方式!
注:在企业级开发过程中,正常情况下不会使用RAM方式进行任务的存储,都是使用JDBC方式。方便学习,这两种方式都进行介绍!

一. Jar包依赖
使用Maven进行Jar包的管理,使用的jar包如下:
<!-- quartz 的jar -->

二.任务类Job
package com.dufy.spring.quartz.chapter01.job;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
* Spring 整合 Quartz 的 Hello World!
* @author dufy
* @date 2017.02.26
*
*/
public class HelloWorldJob implements Job{
private Logger log = LoggerFactory.getLogger(this.getClass());
public void execute(JobExecutionContext arg0) throws JobExecutionException {
log.info("This is a first spring combine quartz !");
log.info("Welcome to Spring_Quartz World!"+ new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()) );
log.info("Let's begin ! \n \n");
}
}
测试类:
package com.dufy.spring.quartz.chapter01.job;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class HWTest {
public static void main(String[] args) {
ApplicationContext ac = new ClassPathXmlApplicationContext("spring_quartz.xml");
}
}
三.配置文件 spring_quartz.xml和运行结果
1:RAM存储方式的xml配置文件
(1):配置文件
<?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"

<!--
Spring整合Quartz进行配置遵循下面的步骤:
1:定义工作任务的Job
2:定义触发器Trigger,并将触发器与工作任务绑定
3:定义调度器,并将Trigger注册到Scheduler
-->
<!-- 1:定义任务的bean ,这里使用JobDetailFactoryBean,也可以使用MethodInvokingJobDetailFactoryBean ,配置类似-->
<bean name="hwJob" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
<!-- 指定job的名称 -->
<property name="name" value="hw_job"/>
<!-- 指定job的分组 -->
<property name="group" value="hw_group"/>
<!-- 指定具体的job类 -->
<property name="jobClass" value="com.dufy.spring.quartz.chapter01.job.HelloWorldJob"/>
<!-- 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会删除该任务 -->
<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>
<!-- 2.1:定义触发器的bean,定义一个Simple的Trigger,一个触发器只能和一个任务进行绑定 -->
<!-- <bean name="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
指定Trigger的名称
<property name="name" value="hw_trigger"/>
指定Trigger的名称
<property name="group" value="hw_trigger_group"/>
指定Tirgger绑定的Job
<property name="jobDetail" ref="hwJob"/>
指定Trigger的延迟时间 1s后运行
<property name="startDelay" value="1000"/>
指定Trigger的重复间隔 5s
<property name="repeatInterval" value="5000"/>
指定Trigger的重复次数
<property name="repeatCount" value="5"/>
</bean> -->
<!-- 2.2:定义触发器的bean,定义一个Cron的Trigger,一个触发器只能和一个任务进行绑定 -->
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<!-- 指定Trigger的名称 -->
<property name="name" value="hw_trigger"/>
<!-- 指定Trigger的名称 -->
<property name="group" value="hw_trigger_group"/>
<!-- 指定Tirgger绑定的Job -->
<property name="jobDetail" ref="hwJob"/>
<!-- 指定Cron 的表达式 ,当前是每隔1s运行一次 -->
<property name="cronExpression" value="0/1 * * * * ?" />
</bean>
<!-- 3.定义调度器,并将Trigger注册到调度器中 -->
<bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<!-- <ref bean="simpleTrigger"/> -->
<ref bean="cronTrigger"/>
</list>
</property>
<!-- <property name="autoStartup" value="true" /> -->
</bean>
</beans>
(2):运行结果
下图为Cron的Trigger运行结果,Simple的Trigger运行结果,可以自行进行查看:
2:JDBC存储方式的xml配置文件
(1):配置文件
<?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/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
<!-- =========JDBC版=========== -->
<!--
持久化数据配置,需要添加quartz.properties
-->
<bean name="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="applicationContextSchedulerContextKey" value="applicationContextKey"/>
<property name="configLocation" value="classpath:quartz.properties"/>
</bean>
</beans>
(2):quartz.properties

(3):HelloWorldJob.java没有改动,HWTest.java修改如下
package com.dufy.spring.quartz.chapter01.job;
import org.quartz.CronScheduleBuilder;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SimpleScheduleBuilder;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.impl.StdScheduler;
import org.quartz.impl.StdSchedulerFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class HWTest {
private static Scheduler scheduler;
public static void main(String[] args) {
ApplicationContext ac = new ClassPathXmlApplicationContext("spring_quartz.xml");
scheduler = (StdScheduler)ac.getBean("scheduler");
startSchedule();
}
public static void startSchedule() {
try {
// 1、创建一个JobDetail实例,指定Quartz
JobDetail jobDetail = JobBuilder.newJob(HelloWorldJob.class)
// 任务执行类
.withIdentity("job1_1", "jGroup1")
// 任务名,任务组
.build();
// 触发器类型
//SimpleScheduleBuilder builder = SimpleScheduleBuilder
// 设置执行次数
//.repeatSecondlyForTotalCount(5);
CronScheduleBuilder builder = CronScheduleBuilder.cronSchedule("0/2 * * * * ?");
// 2、创建Trigger
Trigger trigger = TriggerBuilder.newTrigger()
.withIdentity("trigger1_1", "tGroup1").startNow()
.withSchedule(builder)
.build();
// 3、创建Scheduler
scheduler = StdSchedulerFactory.getDefaultScheduler();
scheduler.start();
// 4、调度执行
scheduler.scheduleJob(jobDetail, trigger);
} catch (SchedulerException e) {
e.printStackTrace();
}
}
}
使用的Cron类型的触发进行存储,运行期间可以在数据库查看到指定的任务已经保存到数据库,并看到控制台打印的信息!
