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! 本篇中的代码下载地址: spring_quartz demo

一、Jar包依赖

使用Maven进行Jar包的管理,使用的jar包如下:

代码语言:javascript复制
<!-- quartz 的jar -->
    <dependency>
		 <groupId>org.quartz-scheduler</groupId>
		 <artifactId>quartz</artifactId>
		 <version>2.2.1</version>
	</dependency>

        <artifactId>quartz-jobs</artifactId>
        <version>2.2.1</version>
    </dependency>
    <!-- spring相关jar -->

    <!-- MySql的包 -->
	<dependency>
		<groupId>mysql</groupId>
		<artifactId>mysql-connector-java</artifactId>

	</dependency>

二、任务类Job

使用 HelloWorldJob 作为任务类!

代码语言:javascript复制
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");
	}

}

HWTest测试类:

代码语言:javascript复制
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

3.1、RAM存储方式的xml配置文件

3.1.1、配置文件
代码语言:javascript复制
<?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"

	<!-- 
		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>
3.1.2、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:

3.2、JDBC存储方式的xml配置文件

3.2.1、Spring配置文件
代码语言:javascript复制
<?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">


	<!-- =========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>
3.2.2 、quartz.properties
代码语言:javascript复制
# Default Properties file for use by StdSchedulerFactory
# to create a Quartz Scheduler Instance, if a different
# properties file is not explicitly specified.
#

#============================================================================
# Configure Main Scheduler Properties
#============================================================================
org.quartz.scheduler.instanceName: dufy_test

#============================================================================
#havent cluster spring

org.quartz.dataSource.qzDS.user:root
org.quartz.dataSource.qzDS.password:root
org.quartz.dataSource.qzDS.maxConnection:10
3.2.3、HelloWorldJob.java没有改动,HWTest.java修改如下
代码语言:javascript复制
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!

3.2.4、输出的结果

四、本文总结

本文在之前的基础上整合了Spring和Quartz,让们对Quartz有更加深入的了解和认识!
