  • 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();

            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:
    #============================================================================
    # 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
