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
LOGGER.debug("#######################init quartz ....###################");
Properties properties = new Properties();
properties.put("org.quartz.scheduler.instanceName","MyClusteredScheduler");

// we must get a reference to a scheduler
SchedulerFactory sf = new StdSchedulerFactory(properties);
sched = sf.getScheduler();

Trigger[] triggers = new Trigger[] { trigger1_1, trigger1_2, trigger2_1, trigger2_2 };
JobDetail[] jobDetails = new JobDetail[] { job1_1, job1_2, job2_1, job2_2 };
for (int i = 0; i < triggers.length; i++) {
JobDetail job = jobDetails[i];
Trigger trigger = triggers[i];
if (sched.checkExists(job.getKey())) {
// the job already exists in jdbcjobstore; let's reschedule it
sched.rescheduleJob(trigger.getKey(), trigger);
LOGGER.info(trigger.getKey() + "@@@@@@@@@@@@@@@@@RESCHEDULEJOB");
} else {
LOGGER.info(trigger.getKey() + "#####################SCHEDULEJOB");
sched.scheduleJob(job, trigger);
}
}
// Start up the scheduler (nothing can actually run until the
// scheduler has been started)
sched.start();
LOGGER.info("------- Scheduler Started -----------------");
// wait long enough so that the scheduler as an opportunity to
// run the job!
try {
Thread.sleep(DURATION_OF_FIRST_SCHEDULING * 1000L);
} catch (Exception e) {
}
}
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：
