quartz分佈式集羣部署而且可視化配置job定時任務
項目使用quartz框架完成了定時任務集羣部署調度，而且對quartz進一步封裝完成在web界面可動態配置定時任務。定時任務若是集羣部署，到達時間點時，同一個任務只能在其中一臺機器上執行。對於quartz框架，其支持分佈式集羣的方案是使用數據庫來加鎖調度。java
如下是quartz分佈式集羣部署，而且能夠動態配置job的代碼。使用了spring和mybatis，數據庫使用了postgresql(用mysql也差很少，只要改下數據源dataSource，以及quartz.properties中的org.quartz.jobStore.driverDelegateClass)。mysql
quartz.properties：web
# Default Properties file for use by StdSchedulerFactory # to create a Quartz Scheduler Instance, if a different # properties file is not explicitly specified. # #org.quartz.scheduler.instanceName: DefaultQuartzScheduler org.quartz.scheduler.instanceName: ClusteredScheduler org.quartz.scheduler.instanceId: AUTO org.quartz.scheduler.rmi.export: false org.quartz.scheduler.rmi.proxy: false org.quartz.scheduler.wrapJobExecutionInUserTransaction: false org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool org.quartz.threadPool.threadCount: 2 org.quartz.threadPool.threadPriority: 5 org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread: true org.quartz.jobStore.class : org.quartz.impl.jdbcjobstore.JobStoreTX ##這裏使用postgresql數據庫 org.quartz.jobStore.driverDelegateClass: org.quartz.impl.jdbcjobstore.PostgreSQLDelegate org.quartz.jobStore.misfireThreshold : 60000 org.quartz.jobStore.useProperties : true org.quartz.jobStore.tablePrefix : QRTZ_ org.quartz.jobStore.isClustered : true org.quartz.jobStore.clusterCheckinInterval : 15000

固然數據庫中還要導入quartz的對應數據源的sql,在下載的quartz-2.2.2-distribution中\docs\dbTables\ 目錄下。本項目中用到postgresql，則是tables_postgres.sql。
