• Quartz学习——Spring和Quartz集成详解(三)


    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!
    :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:

    <!-- quartz 的jar -->
        <dependency>
    		 <groupId>org.quartz-scheduler</groupId>
    		 <artifactId>quartz</artifactId>
    		 <version>2.2.1</version>
    	</dependency>
    	<dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz-jobs</artifactId>
            <version>2.2.1</version>
        </dependency>
        <!-- spring相关jar -->

    			<artifactId>spring-oxm</artifactId>
    			<version>4.0.5.RELEASE</version>
    		</dependency>
        
        <!-- 日志相关jar包 -->
    	<dependency>
    		<groupId>org.slf4j</groupId>
    		<artifactId>slf4j-api</artifactId>
    		<version>1.7.5</version>
    	</dependency>
    	<dependency>
    		<groupId>org.slf4j</groupId>
    		<artifactId>jcl-over-slf4j</artifactId>
    		<version>1.7.5</version>
    	</dependency>
    	<dependency><!--   Failed to load class "org.slf4j.impl.StaticLoggerBinder". -->
    		<groupId>ch.qos.logback</groupId>
    		<artifactId>logback-classic</artifactId>
    		<version>1.0.13</version>
    	</dependency>
        <!-- MySql的包 -->
    	<dependency>
    		<groupId>mysql</groupId>
    		<artifactId>mysql-connector-java</artifactId>
    		<version>5.1.31</version>
    	</dependency>
    

    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 ! 
     
    ");
    	}
    
    }
    
    

    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"
    	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">
    
    	<!-- 
    		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:
    这里写图片描述

    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/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>
    

    (2):quartz.properties

    # Default Properties file for use by StdSchedulerFactory
    # to create a Quartz Scheduler Instance, if a different
    # properties file is not explicitly specified.
    #
    
    #============================================================================

    org.quartz.dataSource.qzDS.user:root
    org.quartz.dataSource.qzDS.password:root
    org.quartz.dataSource.qzDS.maxConnection:10
    

    (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!
