Quartz 在 Spring 中如何动态配置时间

阅读更多

在项目中有一个需求,需要灵活配置调度任务时间,并能自由启动或停止调度。
有关调度的实现我就第一就想到了Quartz这个开源调度组件,因为很多项目使用过,Spring结合Quartz静态配置调度任务时间,非常easy。比如:每天凌晨几点定时运行一个程序,这只要在工程中的spring配置文件中配置好spring整合quartz的几个属性就好。

Spring配置文件

<bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="simpleService" />
<property name="targetMethod" value="test" />
</bean>
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail" ref="jobDetail" />
<property name="cronExpression" value="0 0/50 * ? * * *" />
</bean>
<bean  id="schedulerTrigger" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="cronTrigger"/>     
</list>
</property>
</bean> 

 这种配置就是对quartz的一种简单的使用了,调度任务会在spring启动的时候加载到内存中,按照cronTrigger中定义的 cronExpression定义的时间按时触发调度任务。但是这是quartz使用“内存”方式的一种配置,也比较常见,当然对于不使用spring的项目,也可以单独整合quartz。方法也比较简单,可以从quartz的doc中找到配置方式,或者看一下《Quartz Job Scheduling Framework 》。

但是对于想持久化调度任务的状态,并且灵活调整调度时间的方式来说,上面的内存方式就不能满足要求了,正如本文开始我遇到的情况,需要采用数据库方式集成 Quartz,这部分集成其实在《Quartz Job Scheduling Framework 》中也有较为详细的介绍,当然doc文档中也有,但是缺乏和spring集成的实例。

一、需要构建Quartz数据库表,建表脚本在Quartz发行包的docs\dbTables目录,里面有各种数据库建表脚本,例子中采用的Quartz 2.2.1版本,使用H2内存数据库,执行了Quartz发行包的docs\dbTables\tables_h2.sql建表。

二、建立Maven project,完成后目录如下


 

三、配置applicationContext.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="   
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsd
   http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
   ">
    <context:component-scan base-package="com.sundoctor" />		
    <!-- 使用H2内存数据库并创建quartz数据库表 -->
    <jdbc:embedded-database id="dataSource" type="H2">
        <jdbc:script location="classpath:db/tables_h2.sql"/>       
    </jdbc:embedded-database>
</beans>

 
这里只是配置了数据库连接dataSource,为了简单方便,我使用H2内存数据库,执行tables_h2.sql创建quartz数据库表,还没有涉及到quartz有关配置,下面且听我慢慢道来。

四、实现动态定时任务
  什么是动态定时任务:是由客户制定生成的,服务端只知道该去执行什么任务,但任务的定时是不确定的(是由客户制定)。
这样总不能修改配置文件每定制个定时任务就增加一个trigger吧,即便允许客户修改配置文件,但总需要重新启动web服务啊,研究了下Quartz在Spring中的动态定时,发现

<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail" ref="jobDetail" />
<property name="cronExpression" value="0 0/50 * ? * * *" />
</bean> 

 

cronExpression是关键,如果可以动态设置cronExpression的值,就可以顺利解决问题了。这样我们就不能直接使用org.springframework.scheduling.quartz.CronTriggerFactoryBean,需要自己实现一个动态调度服务类,在其中构建CronTrigger或SimpleTrigger,动态配置时间。
动态调度服务接口:

}

 

SchedulerService 只有一个多态方法schedule,SchedulerServiceImpl实现SchedulerService接口,注入org.quartz.Schedulert和org.quartz.JobDetail,schedule方法可以动态配置org.quartz.CronExpression或org.quartz.SimpleTrigger调度时间。

五、实现自己的org.quartz.JobDetail

 

package com.sundoctor.example.service;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.SchedulerException;
import org.quartz.Trigger;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;

public class MyQuartzJobBean extends QuartzJobBean {

	private static final Logger logger = LoggerFactory.getLogger(MyQuartzJobBean.class);

	@Override
	protected void executeInternal(JobExecutionContext jobexecutioncontext) throws JobExecutionException {
		Trigger trigger = jobexecutioncontext.getTrigger();
		String triggerName = trigger.getKey().getName();

		SimpleService simpleService = getApplicationContext(jobexecutioncontext).getBean("simpleService",
				SimpleService.class);
		simpleService.testMethod(triggerName);

	}

	private ApplicationContext getApplicationContext(final JobExecutionContext jobexecutioncontext) {
		try {
			return (ApplicationContext) jobexecutioncontext.getScheduler().getContext().get("applicationContextKey");
		} catch (SchedulerException e) {
			logger.error("jobexecutioncontext.getScheduler().getContext() error!", e);
			throw new RuntimeException(e);
		}
	}

}

 

MyQuartzJobBean继承org.springframework.scheduling.quartz.QuartzJobBean,SimpleService如下:

package com.sundoctor.example.service;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Service;

@Service("simpleService")
public class SimpleService {

	private static final Logger logger = LoggerFactory.getLogger(SimpleService.class);

	public void testMethod(String triggerName) {
		// 这里执行定时调度业务
		logger.info(triggerName);
	}

}


SimpleService主要执行定时调度业务,在这里我只是简单打印一下log日志。
配置applicationContext-quartz.xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	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.xsd">

	<bean name="quartzScheduler"
		class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="applicationContextSchedulerContextKey" value="applicationContextKey" />
		<property name="configLocation" value="classpath:quartz.properties" />
	</bean>

	<bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
		<property name="jobClass">
			<value>com.sundoctor.example.service.MyQuartzJobBean</value>
		</property>	
		<property name="durability" value="true" />	
	</bean>

</beans>

 
dataSource:项目中用到的数据源,里面包含了quartz用到的数据库表;
applicationContextSchedulerContextKey: 是org.springframework.scheduling.quartz.SchedulerFactoryBean这个类中把spring上下文以key/value的方式存放在了quartz的SchedulerContext,可以用applicationContextSchedulerContextKey所定义的key得到spring的ApplicationContext,然后就可使用ApplicationContext取得spring beans,使用方法参见MyQuartzJobBean;
configLocation:用于指明quartz的配置文件的位置,如果不用spring配置quartz的话,本身quartz是通过一个配置文件进行配置的,默认名称是quartz.properties,里面配置的参数在quartz的doc文档中都有介绍,可以调整quartz,我在项目中也用这个文件部分的配置了一些属性,代码如下:

org.quartz.scheduler.instanceName = DefaultQuartzScheduler
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 10
org.quartz.threadPool.threadPriority = 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true

org.quartz.jobStore.misfireThreshold = 60000

#org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
#org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.HSQLDBDelegate
org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#org.quartz.jobStore.useProperties = true
org.quartz.jobStore.tablePrefix = QRTZ_ 
org.quartz.jobStore.isClustered = false 
org.quartz.jobStore.maxMisfiresToHandleAtATime=1 

 


这里面没有数据源相关的配置部分,采用spring注入datasource的方式已经进行了配置。

六、测试
运行如下测试类

package com.sundoctor.example.test;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

import org.quartz.SchedulerException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.sundoctor.quartz.service.SchedulerService;

public class MainTest {

	/**
	 * @param args
	 * @throws SchedulerException
	 */
	public static void main(String[] args) throws SchedulerException {

		ApplicationContext springContext = new ClassPathXmlApplicationContext(new String[] {
				"classpath:applicationContext.xml", "classpath:applicationContext-quartz.xml" });
		SchedulerService schedulerService = springContext.getBean("schedulerService", SchedulerService.class);

		// 执行业务逻辑...

		// 设置高度任务
		// 每10秒中执行调试一次
		schedulerService.schedule("0/10 * * ? * * *");

		Date startTime = parse("2014-08-19 16:33:00");
		Date endTime = parse("2014-08-22 21:10:00");

		// 2014-08-19 16:33:00开始执行调度
		schedulerService.schedule(startTime);

		// 2014-08-19 16:33:00开始执行调度,2014-08-22 21:10:00结束执行调试
		schedulerService.schedule(startTime, endTime);

		// 2014-08-19 16:33:00开始执行调度,执行5次结束
		schedulerService.schedule(startTime, 5);

		// 2014-08-19 16:33:00开始执行调度,每隔20秒执行一次,执行5次结束
		schedulerService.schedule(startTime, 5, 20);

		// 等等,查看com.sundoctor.quartz.service.SchedulerService

	}

	private static Date parse(String dateStr) {
		SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		try {
			return format.parse(dateStr);
		} catch (ParseException e) {

这样只是简单的将quartz trigger名称打印出来。

这样通过SchedulerService就可以动态配置调度时间。其实SchedulerService 还可扩展,比如可以注入多个JobDetail,调度不同的JobDetail。

按照群主你的Quartz任务监控管理 的配值,如何让任务变成有状态的任务,不能并发,就是加上<property name="concurrent" value="false" />



我已经可以动态加载,但是任务还是并发,把这句代码放在那里,可以让他不并发。



底下是我要完成的要求

在quartz和sping整合中动态执行加载的定时任务,定时任务是有状态的,不能并发。

这么多年了,不知道楼主还记得不记得这篇文章了
quartz有两种方式:RAMJobStore和JdbcJobStore两种
遇到个问题,跑了下楼主的QuartzWithSpring项目,发现不管我怎么修改,
都会采用持久数据的方式,RAMJobStore无法使用,好纠结啊。试了很多种方法都不行

org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

我来回答自己的问题吧:
折腾了好几天,进入quartz源码调试一番才知道,是下面这个东西在搞鬼
org.quartz.scheduler.instanceName = StoreQuartzScheduler_1
这个名字要不能重复,而且自由定义,工程中spring已经加载了class name 为DefaultQuartzScheduler的实例,所以我配置的没用了,就一直默认采用RAM方式
quartz版本1.6.6
StdSchedulerFactory 的1377行代码

    public Scheduler getScheduler() throws SchedulerException {
        if (cfg == null) {
            initialize();
        }

        SchedulerRepository schedRep = SchedulerRepository.getInstance();

        Scheduler sched = schedRep.lookup(getSchedulerName());

        if (sched != null) {
            if (sched.isShutdown()) {
                schedRep.remove(getSchedulerName());
            } else {
                return sched;//这里居然给我自动返回了
            }
        }

        sched = instantiate();//改了之后才执行这段代码

        return sched;
    }

对spring的单例注入方式真是 哎,希望对遇到同样问题的人有用
