quartz是一个任务调度框架,具体的用途比如说,我想我的程序在每天的3点干什么事,每隔多长时间做一件什么事。quartz框架就可以完美地解决这些。
1.xml配置方式
首先我是用spring来管理的的项目的,所以我直接在spring的配置文件中配置我的任务即可!(我是用的quartz2.2.1版本),需要俩包,quartz的包,和slf4j-api-1.7.25.jar
废话不多述,直接上代码
<bean id="job_1" class="com.yiwei.mytask.Job1" /> <bean id="job1" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <property name="targetObject" ref="job_1" /> <property name="targetMethod" value="doJob1" /> <property name="concurrent" value="false" /> </bean> <!-- 调度触发器 --> <bean id="cronTrigger1" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean"> <property name="jobDetail" ref="job1" /> <property name="cronExpression" value="0/5 * * * * ?" /> </bean> <!-- 调度工厂 --> <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <!-- 触发器列表 --> <ref bean="cronTrigger1" /> </list> </property> </bean>
第一个bean 中的id =“job_1” 是指这个任务的执行类,然后调度任务时候,必须把触发器的id写到ref中去。才能完成调用。
然而,用这种方式写,又一个很大的弊端,就是不够灵活。接下来介绍数据库方式持久化。
2.数据库方式
在 /docs/dbTables 目录下存放了几乎所有数据库的的SQL脚本,这里的 是解压 Quartz 分发包后的目录。我们使用常用oracle数据库,下面是示例sql脚本代码
-- -- A hint submitted by a user: Oracle DB MUST be created as "shared" and the -- job_queue_processes parameter must be greater than 2 -- However, these settings are pretty much standard after any -- Oracle install, so most users need not worry about this. -- -- Many other users (including the primary author of Quartz) have had success -- runing in dedicated mode, so only consider the above as a hint ;-) -- delete from qrtz_fired_triggers;

其中各表的含义如下所示:
表名 | 描述 |
---|---|
QRTZ_CALENDARS | 以 Blob 类型存储 Quartz 的 Calendar 信息 |
QRTZ_CRON_TRIGGERS | 存储 Cron Trigger,包括 Cron 表达式和时区信息 |
QRTZ_FIRED_TRIGGERS | 存储与已触发的 Trigger 相关的状态信息,以及相联 Job 的执行信息 |
QRTZ_PAUSED_TRIGGER_GRPS | 存储已暂停的 Trigger 组的信息 |
QRTZ_SCHEDULER_STATE | 存储少量的有关 Scheduler 的状态信息,和别的 Scheduler 实例(假如是用于一个集群中) |
QRTZ_LOCKS | 存储程序的非观锁的信息(假如使用了悲观锁) |
QRTZ_JOB_DETAILS | 存储每一个已配置的 Job 的详细信息 |
QRTZ_JOB_LISTENERS | 存储有关已配置的 JobListener 的信息 |
QRTZ_SIMPLE_TRIGGERS | 存储简单的 Trigger,包括重复次数,间隔,以及已触的次数 |
QRTZ_BLOG_TRIGGERS Trigger | 作为 Blob 类型存储(用于 Quartz 用户用 JDBC 创建他们自己定制的 Trigger 类型,JobStore 并不知道如何存储实例的时候) |
QRTZ_TRIGGER_LISTENERS | 存储已配置的 TriggerListener 的信息 |
QRTZ_TRIGGERS | 存储已配置的 Trigger 的信息 |
2.我的一个quartz.properties属性文件配置实例:
org.quartz.scheduler.instanceName = MyScheduler org.quartz.threadPool.threadCount = 3 org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.oracle.OracleDelegate org.quartz.jobStore.tablePrefix = QRTZ_ org.quartz.jobStore.dataSource = myDS org.quartz.dataSource.myDS.driver = oracle.jdbc.driver.OracleDriver org.quartz.dataSource.myDS.URL = jdbc:oracle:thin:@localhost:1521:xe org.quartz.dataSource.myDS.user = wanan org.quartz.dataSource.myDS.password = wanan org.quartz.dataSource.myDS.maxConnections =10
3.然后进行我们的增删改,以及启动,运行 操作
添加一个调度任务
//添加定时任务 @Override public int addjobgroup(QuartzJob quartzjob,Class<T> entity) throws Exception { JobDetail jobDetail = JobBuilder.newJob((Class<? extends Job>) entity) .withIdentity(quartzjob.getJob_name(), quartzjob.getJob_group()) .withDescription(quartzjob.getDescription()) .build(); //表达式调度构建器 CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(quartzjob.getCron_expression()); CronTrigger cronTrigger = (CronTrigger) TriggerBuilder .newTrigger() .withIdentity(quartzjob.getTrigger_name()) .withSchedule(scheduleBuilder) .startNow() .build(); //创建scheduler SchedulerFactory schedulerFactory = new StdSchedulerFactory(); Scheduler scheduler = schedulerFactory.getScheduler(); scheduler.scheduleJob(jobDetail, cronTrigger); scheduler.start(); return 1; }
删除一个调度任务
//删除定时任务 @Override public int deljobgroup(String trigger_name) { SchedulerFactory schedulerFactory = new StdSchedulerFactory(); TriggerKey triggerkey = new TriggerKey(trigger_name); try { Scheduler scheduler = schedulerFactory.getScheduler(); scheduler.unscheduleJob(triggerkey);// 移除触发器 } catch (SchedulerException e) { e.printStackTrace(); } return 1; }
暂停一个任务
//暂停某任务 @Override public int pauseTrigger(String triggerName) { SchedulerFactory schedulerFactory = new StdSchedulerFactory(); TriggerKey triggerkey = new TriggerKey(triggerName); try { Scheduler scheduler = schedulerFactory.getScheduler(); scheduler.pauseTrigger(triggerkey); // 暂停任务 } catch (SchedulerException e) { e.printStackTrace(); } return 1; }
重新启动某任务
//重新开始某任务 @Override public int resumeTriggers(String triggerName) { SchedulerFactory schedulerFactory = new StdSchedulerFactory(); TriggerKey triggerkey = new TriggerKey(triggerName); try { Scheduler scheduler = schedulerFactory.getScheduler(); scheduler.resumeTrigger(triggerkey); // 重新开始某任务 } catch (SchedulerException e) { e.printStackTrace(); } return 1; }
更新某任务比较简单,即先删除此任务,再重新添加。
