quartz scheduler 2.16 之集群

现在最新版本的quartz是2.16,这里简单介绍下这个版本下的集群。尝试过与spring的整合,但好像spring对这个版本还没办法整合,总有错。

先下载http://quartz-scheduler.org/downloads/catalog 然后运行quartz-2.1.6\docs\dbTables\tables_mysql_innodb.sql

先通过 properties构造 SchedulerFactory ,把job持久到数据库

SchedulerFactory sf = new StdSchedulerFactory(properties);

然后添加job,trigger到
SchedulerFactory

Properties 相关参数介绍如下:
#============================================================================
# Configure Main Scheduler Properties  
#============================================================================
#instanceName属性可为任何值,用在 JDBC JobStore 中来唯一标识实例,但是所有集群节点中必须相同 
org.quartz.scheduler.instanceName=MyClusteredScheduler
#属性为 AUTO即可,基于主机名和时间戳来产生实例 ID
org.quartz.scheduler.instanceId=AUTO

#============================================================================
# Configure ThreadPool  
#============================================================================

org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount=25
org.quartz.threadPool.threadPriority=5

#============================================================================
# Configure JobStore  
#============================================================================

org.quartz.jobStore.misfireThreshold=60000
#属性为 JobStoreTX将任务持久化到数据中。因为集群中节点依赖于数据库来传播 
org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.useProperties=true
org.quartz.jobStore.dataSource=myDS
org.quartz.jobStore.tablePrefix=QRTZ_

#属性为 true,你就告诉了 Scheduler 实例要它参与到一个集群当中。这一属性会贯穿于调度框架的始终,用于修改集群环境中操作的默认行为 
org.quartz.jobStore.isClustered=true
#属性定义了Scheduler 实例检入到数据库中的频率(单位:毫秒)
org.quartz.jobStore.clusterCheckinInterval=20000

#============================================================================
# Configure Datasources  
#============================================================================

org.quartz.dataSource.myDS.driver=com.mysql.jdbc.Driver
org.quartz.dataSource.myDS.URL=jdbc:mysql://localhost:3306/jtxw?useUnicode=true&characterEncoding=utf8
org.quartz.dataSource.myDS.user=root
org.quartz.dataSource.myDS.password=root
org.quartz.dataSource.myDS.maxConnections=5
org.quartz.dataSource.myDS.validationQuery=select 1
