  • java定时任务(二):Quartz

      Quartz是OpenSymphony开源组织在任务调度领域的一个开源项目,完全基于Java实现。Quartz具备以下特点:

        1.强大的调度功能,例如支持丰富多样的调度方法,可以满足各种常规及特殊需求;

        2.灵活的应用方式,例如支持任务和调度的多种组合方式,支持调度数据的多种存储方式;

        3.分布式和集群能力

      Quartz由于功能强大,又能够很轻易的就与spring集成在一起,所以实际开发中经常会用到。

    一、引入Quartz包

            <!-- quartz -->
            <dependency>
                <groupId>org.quartz-scheduler</groupId>
                <artifactId>quartz</artifactId>
                <version>2.2.3</version>
            </dependency>
            <dependency>
                <groupId>org.quartz-scheduler</groupId>
                <artifactId>quartz-jobs</artifactId>
                <version>2.2.3</version>
            </dependency>

    二、详细配置

      2.1 xml配置

    <?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:context="http://www.springframework.org/schema/context"
           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.xsd">
    
        <!-- 1:定义任务的bean ,这里使用JobDetailFactoryBean,也可以使用MethodInvokingJobDetailFactoryBean-->
        <bean name="testJob" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
            <property name="name" value="test_job"/>
            <property name="group" value="test_group"/>
            <property name="jobClass" value="com.sawyer.job.TestJob"/>
        </bean>
    
        <!--<bean name="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
           <property name="name" value="test_trigger"/>
           <property name="group" value="test_trigger_group"/>
           <property name="jobDetail" ref="testJob"/>
           <property name="startDelay" value="1000"/>
           <property name="repeatInterval" value="5000"/>
           <property name="repeatCount" value="15"/>
       </bean>-->
    
        <!-- 定义触发器,并与job关联 -->
        <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
            <property name="name" value="test_trigger"/>
            <property name="group" value="test_trigger_group"/>
            <property name="jobDetail" ref="testJob"/>
            <property name="startDelay" value="3000"/>
            <property name="cronExpression" value="0/5 * * * * ?"/>
        </bean>
    
        <!-- 定义调度器,并将Trigger注册到调度器中 -->
        <bean id="schedulers" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
            <property name="jobFactory">
                <bean class="com.sawyer.job.AutowiringSpringBeanJobFactory"></bean>
            </property>
            <property name="applicationContextSchedulerContextKey" value="applicationContext"/>
            <property name="triggers">
                <list>
                    <!--<ref bean="simpleTrigger"/>-->
                    <ref bean="cronTrigger"/>
                </list>
            </property>
            <property name="autoStartup" value="true"/>
        </bean>
    </beans>

      使用quartz需要配置job、trigger、scheduler,其中:

      job:任务的执行类,需要在xml中指明名称、组别和类

      trigger:任务的触发器,需要指明名称、组别以及关联的job。一个触发器只能对应一个job;触发器有两种,分别为CronTriggerFactoryBean和SimpleTriggerFactoryBean,前者支持cron表达式,后者只支持一些简单的配置。

      scheduler:调度器,需要将trigger配置在scheduler的triggers中,可以配置多个。这里自定义实现了jobFactory,可以在job中自动注入spring bean;applicationContextSchedulerContextKey属性用于在job中获取spring 的上下文。

      2.2 代码清单

      2.2.1 AutowiringSpringBeanJobFactory

    package com.sawyer.job;
    
    import org.quartz.spi.TriggerFiredBundle;
    import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.ApplicationContextAware;
    import org.springframework.scheduling.quartz.SpringBeanJobFactory;
    
    public class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware {
        private transient AutowireCapableBeanFactory beanFactory;
    
        public void setApplicationContext(final ApplicationContext context) {
            beanFactory = context.getAutowireCapableBeanFactory();
        }
    
        @Override
        public Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
            final Object job = super.createJobInstance(bundle);
            beanFactory.autowireBean(job);
            return job;
        }
    }

      自定义实现了JobFactory,就可以在job中自动注入bean

      2.2.2 AbstractJob

    package com.sawyer.job;
    
    import org.quartz.Job;
    import org.quartz.JobExecutionContext;
    import org.quartz.JobExecutionException;
    
    /**
     * 抽象类,job需要继承该类,通过这种方式可以做一些自定义处理
     */
    public abstract class AbstractJob implements Job {
    
        @Override
        public final void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
            try {
                safeExecute(jobExecutionContext);
            } catch (Exception e) {
                JobExecutionException e2 = new JobExecutionException(e);
    
                if (!ignoreException()) {
                    if (isRefireImmediatelyWhenException()) {
                        //立即重新运行当前job
                        e2.setRefireImmediately(true);
                    } else {
                        //立即停止与当前Job有关的所有触发器,当前job不会再运行
                        e2.setUnscheduleAllTriggers(true);
                    }
                }
                throw e2;
            }
        }
    
    
        public abstract void safeExecute(JobExecutionContext context) throws Exception;
    
        /**
         * 是否忽略job运行时产生的异常
         */
        public abstract boolean ignoreException();
    
        /**
         * 发生异常时是否立即重新执行JOB或将JOB挂起.
         * <p>
         *
         * @return {@code true} Job运行产生异常时,立即重新执行JOB. <br>
         * {@code false} Job运行产生异常时,挂起JOB等候管理员处理.
         */
        public abstract boolean isRefireImmediatelyWhenException();
    }

      AbstractJob是一个抽象类,凡是job都应该继承该类,通过这种方式可以job做一些自定义处理。如图中代码所示,AbstractJob中有4个方法:

        ignoreException:是否忽略异常,返回true时忽略异常,否则必须处理。

        isRefireImmediatelyWhenException:当出现异常时,是否立即重新执行。返回true时,立即重新执行,否则将会挂起所有与该job有关的trigger,不再执行。

        safeExecute:子类需要实现该方法,在方法中定义具体的实现逻辑。

        execute:接口job的实现方法,job最终是在该方法中执行的。只有这个方法才是Job自带的,其他的都是自定义方法。

      2.2.3 TestJob

      

    package com.sawyer.job;
    
    import org.quartz.DisallowConcurrentExecution;
    import org.quartz.JobDataMap;
    import org.quartz.JobExecutionContext;
    import org.quartz.PersistJobDataAfterExecution;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.ApplicationContext;
    import org.springframework.data.redis.core.RedisTemplate;
    
    import java.util.Date;
    
    @PersistJobDataAfterExecution
    @DisallowConcurrentExecution
    public class TestJob extends AbstractJob {
    
        private static final String COUNT_KEY = "count";
    
        private static final String APPLICATION_CONTEXT_KEY = "applicationContext";
    
        @Autowired
        private RedisTemplate redisTemplate;
    
        @Override
        public void safeExecute(JobExecutionContext context) throws Exception {
    
            //统计执行次数
            JobDataMap jobDataMap = context.getJobDetail().getJobDataMap();
            int count = 0;
            if (jobDataMap.containsKey(COUNT_KEY)) {
                count = (int) jobDataMap.get(COUNT_KEY);
            }
            count++;
            jobDataMap.put(COUNT_KEY, count);
    
            //打印出redisTemplate,测试是否能自动注入
            System.out.println("autowiring spring bean :" + redisTemplate);
    
            //获取spring上下文
            ApplicationContext applicationContext = (ApplicationContext) context.getScheduler().getContext().get(APPLICATION_CONTEXT_KEY);
            System.out.println("spring context :" + applicationContext);
            if (10 == count) {
                int m = 1 / 0;
            }
    
            System.out.println("********current date :" + new Date() + " and the thread is :" + Thread.currentThread().getName() + " and the count is :" + count + " **********");
    
        }
    
        @Override
        public boolean isRefireImmediatelyWhenException() {
            return false;
        }
    
        @Override
        public boolean ignoreException() {
            return false;
        }
    }

      Quartz默认是支持并发的,即上一个任务未完成的时候就开始了下一个任务,并且每次都是生成一个新的job实例。图中例子由于需要共享count,统计次数,所在TestJob上面加了两个注解@PersistJobDataExecution和@DisallowConcurrentExecution,这是用于持久化JobData和禁用并发的。加了这两个注解就能够让testJob成为一个有状态的job,并且上一次任务执行完后,才开始下一次任务,这样一来就可以通过jobDataMap共享数据,反之,如果不加注解的话,job就是一个无状态的job,每次运行时都会产生一个新的job实例,数据无法共享。而禁用并发是为了防止并发产生数据紊乱的问题。

      TestJob中isRefireImmediatelyWhenException和ignoreException都为false,那么当count等于10时,会抛出异常,系统就会将于当前job有关有的所有trigger挂起,不再执行job。

      运行结果如下:

     三、Quartz 存储与持久化

      Quartz提供了两种作业存储类型,分别为RAMJobSore和JDBCJobStore。

      RASMJobStore:将作业的调度信息存储到内存中,不需要配置外置数据库,配置简单,运行速度快;但是由于调度信息存储在内存中,当应用程序停止时,作业的调度信息将会丢失,此外一旦作业运行期间崩溃,将无法恢复事故现场,比如原定执行30次,执行到第15次是崩溃了,那么系统重启时,将会从0开始。

      JDBCJobStore:将作业的调度信息存储到数据库中,该种方式支持集群,调度信息不会丢失,并且可以手动恢复意外停止的job;但是这种方式会较为复杂。

      Quartz默认使用的就是RAMJobStore,下面开始介绍持久化配置。

      3.1 创建quartz数据表

        3.1.1 下载源码包:http://www.quartz-scheduler.org/downloads/

        3.1.2 在quartz-2.2.3/docs/dbTables目录下找到与数据库对应的sql文件,我使用的是mysql数据库,所以这里选择tables.mysql.sql文件,在数据库中执行。

        3.1.3 表结构为:

        

      3.2 引入 quartz.properties ,并根据业务需要进行配置。

    #
    # #{copyright}#
    #
    
    org.quartz.jobStore.isClustered = true
    org.quartz.jobStore.clusterCheckinInterval = 20000
    org.quartz.scheduler.instanceId = AUTO
    org.quartz.scheduler.skipUpdateCheck = true
    
    # 集群配置
    org.quartz.scheduler.instanceName = DefaultQuartzScheduler
    org.quartz.scheduler.rmi.export = false
    org.quartz.scheduler.rmi.proxy = false
    org.quartz.scheduler.wrapJobExecutionInUserTransaction = false
    
    
    # 线程池的实现类
    org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
    # 线程数量
    org.quartz.threadPool.threadCount = 10
    # 线程优先级,最大值为10,最小值为1
    org.quartz.threadPool.threadPriority = 5
    #
    org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true
    
    # 持久化配置
    #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.scheduler.classLoadHelper.class=org.quartz.simpl.CascadingClassLoadHelper
    #org.quartz.jobStore.useProperties = true
    org.quartz.jobStore.tablePrefix = QRTZ_
    org.quartz.jobStore.maxMisfiresToHandleAtATime=1
    org.quartz.jobStore.selectWithLockSQL=SELECT * FROM {0}LOCKS UPDLOCK WHERE LOCK_NAME = ?
    org.quartz.jobStore.misfireThreshold = 60000
    
    #============================================================================
    # 配置插件
    #============================================================================
    #org.quartz.plugin.triggHistory.class=org.quartz.plugins.history.LoggingJobHistoryPlugin
    org.quartz.plugin.runningListener.class=com.sawyer.job.RunningListenerPlugin
    org.quartz.plugin.runningListener.LogRunningInfo=true

      我在quartz.properties中,配置了一个自定义的插件:com.sawyer.job.RunningListenerPlugin,可以在这里做一些比较有意义的事情。另外就是,我并没有将数据库信息配置在quart.properties中,而是选择另行配置,目的为了将数据库信息集中到一起,方便操作,实际项目中,也推荐使用这种方式。

      3.3 application-data.xml

    <?xml version="1.0" encoding="UTF-8"?>

      3.4 application-job.xml

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

            <property name="configLocation" value="classpath:quartz.properties"/>
        </bean>
    </beans>

      这一步的scheduler配置与上文的基本一致,只是配置了dataSource和引入了quartz.properties文件

      3.5 自定义插件 RunningListenerPlugin

    /*
     * #{copyright}#
     */
    package com.sawyer.job;
    
    import org.quartz.ListenerManager;
    import org.quartz.Scheduler;
    import org.quartz.SchedulerException;
    import org.quartz.impl.matchers.EverythingMatcher;
    import org.quartz.spi.ClassLoadHelper;
    import org.quartz.spi.SchedulerPlugin;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.context.ApplicationContext;
    
    public class RunningListenerPlugin implements SchedulerPlugin {
    
        private final Logger log = LoggerFactory.getLogger(getClass());
    
        private Scheduler scheduler;
    
        private boolean isLogRunningInfo;
    
        @Override
        public void initialize(String s, Scheduler scheduler, ClassLoadHelper classLoadHelper) throws SchedulerException {
            this.scheduler = scheduler;
            System.out.println("##################  调度器初始化 ##################");
        }
    
        @Override
        public void start() {
            System.out.println("##################  调度器启动 ###################");
            try {
                ApplicationContext applicationContext = (ApplicationContext) scheduler.getContext().get("applicationContext");
    
                System.out.println("获取到的 ApplicationContext :" + applicationContext);
    
                ListenerManager listenerManager = scheduler.getListenerManager();
                if (isLogRunningInfo()) {
                    listenerManager.addJobListener(new JobRunningListener(applicationContext), EverythingMatcher.allJobs());
                    listenerManager.addSchedulerListener(new SchedulerRunningListener(applicationContext));
                }
    
            } catch (SchedulerException e) {
                throw new RuntimeException(e);
            }
        }
    
        @Override
        public void shutdown() {
            System.out.println("############# 调度器关闭 ##################");
        }
    
    
        public boolean isLogRunningInfo() {
            return isLogRunningInfo;
        }
    
        public void setLogRunningInfo(boolean logRunningInfo) {
            isLogRunningInfo = logRunningInfo;
        }
    }

      可以添加多个监听器,实现各种各样的业务需求,比如用于任务结束后发邮件,记录更为详细的运行信息等。只需要实现响应的接口即可,这里我选择了添加JobRunningListener和SchedulerRunningListener。

      JobRunningListener

    /*
     * #{copyright}#
     */
    package com.sawyer.job;
    
    import org.quartz.*;
    import org.springframework.context.ApplicationContext;
    
    public class JobRunningListener implements JobListener {
    
        private final static String LISTENER_NAME = "JobRunningListener";
    
        private ApplicationContext applicationContext;
    
        public JobRunningListener(ApplicationContext applicationContext) {
            this.applicationContext = applicationContext;
        }
    
        @Override
        public String getName() {
            return LISTENER_NAME;
        }
    
        @Override

      3.6 执行调用

    package com.sawyer;
    
    import com.sawyer.job.AbstractJob;
    import org.quartz.*;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    public class Main {
        private static final Logger logger = LoggerFactory.getLogger(Main.class);
    
        public static void main(String[] args) {
            String configLocation = "classpath:spring/applicationContext*.xml";
            ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(configLocation);
    
            try {
                createJob(context);
            } catch (SchedulerException e) {
                e.printStackTrace();
            }
            logger.info("Container has been startup.");
        }
    
    
        public static void createJob(ApplicationContext context) throws SchedulerException {
    
            final String jobClassName = "com.sawyer.job.TestJob";
            final String jobName = "test_job";
            final String jobGroup = "test_group";
            final String jobDescription = "这是TestJob的描述信息";
            final String triggerName = "test_trigger";
            final String triggerGroup = "test_trigger_group";
            final String cron = "0/5 * * * * ?";
    
            // 加载job类,并判断 job类的父类是否为AbstractJob
            boolean assignableFrom = false;
            Class forName = null;
            try {
                forName = Class.forName(jobClassName);
                assignableFrom = AbstractJob.class.isAssignableFrom(forName);
            } catch (ClassNotFoundException e) {
                if (logger.isErrorEnabled()) {
                    logger.error(e.getMessage(), e);
                }
            }
    
            JobBuilder jb = JobBuilder.newJob(forName).withIdentity(jobName, jobGroup)
                    .withDescription(jobDescription);
    
            //放入数据
            JobDataMap data = new JobDataMap();
            data.put("count", 5);
            jb = jb.usingJobData(data);
    
            JobDetail jobDetail = jb.build();
    
            TriggerBuilder<Trigger> triggerBuilder = TriggerBuilder.newTrigger()
                    .withIdentity(triggerName, triggerGroup).forJob(jobDetail);
    
            ScheduleBuilder sche = CronScheduleBuilder.cronSchedule(cron);
    
            Trigger trigger = triggerBuilder.withSchedule(sche).build();
    
            Scheduler quartzScheduler = (Scheduler) context.getBean("quartzScheduler");
            quartzScheduler.scheduleJob(jobDetail, trigger);
        }
    
    
    }

      这里使用的job类仍然是上文中的TestJob,只是改用程序生成调用而已,另外这里的count我手动赋值成了5

      3.7 运行结果:

      查看数据表,可以发现已经新增了相关的记录了:  

      到此,quartz持久化配置就完成了。

    四、 Job操作

      quartz是通过jobName和jobGroup来区分job的,所以job的name和group一定要填写,然后通过这个就可以对job进行添加、暂停、恢复和删除了。

      添加:quartzScheduler.scheduleJob(jobDetail,trigger)

      暂停:quartzScheduler.pauseJob(JobKey.jobKey(jobName,jobGroup))

      恢复:quartzSchduler.resumeJob(JobKey.jobKey(jobName,jobGroup))

      删除:quartScheduler.deleteJob(JobKey.jobKey(jobName,jobGroup))

      通过这些方法就可以对job做一些基本的管理了,体现在web上的效果,如下:
