Quartz集群
1、quartz的集群或者说高可用是通过数据库行锁实现的，所以，quartz的高可用性能其实并不高，但是可以适用大部分的中小型定时任务场景。
2、重要：根据官网说明，不要在同一个节点上启用集群，原因大约就是时钟的问题。
3、quartz集群与单节点实现上，主要差别是在配置文件上。Quartz实现动态定时任务
4、集群配置：
spring:
# 非集群方式以下关于quartz的配置都可以删除
quartz:
# 集群名称，相同的名字归属同一个集群
scheduler-name: wood-cluster
# Job 存储器类型。默认为 memory 表示内存，集群选 jdbc 使用数据库。
job-store-type: jdbc
jdbc:
# 使用 JDBC 的 JobStore 的时候，是否自动使用 SQL 初始化 Quartz 表结构。
initialize-schema: never
# Quartz 是否自动启动
auto-startup: true
# 延迟 N 秒启动
startup-delay: 0
# 应用关闭时，是否等待定时任务执行完成。默认为 false ，建议设置为 true
wait-for-jobs-to-complete-on-shutdown: true
# 是否覆盖已有 Job 的配置
overwrite-existing-jobs: false
properties:
org:
quartz:
scheduler:
instanceName: wood-instance
instanceId: AUTO
# JobStore 相关配置
jobStore:
# 数据源名称
dataSource: dataSource # 使用的数据源
class: org.quartz.impl.jdbcjobstore.JobStoreTX # JobStore 实现类
# oracle换成： OracleDelegate
driverDelegateClass: org.quartz.impl.jdbcjobstore.StdJDBCDelegate
txIsolationLevelSerializable: true
tablePrefix: qrtz_ # Quartz 表前缀
isClustered: true # 是集群模式
clusterCheckinInterval: 15000
useProperties: false
# 线程池相关配置
threadPool:
threadCount: 25 # 线程池大小。默认为 10 。
threadPriority: 5 # 线程优先级
class: org.quartz.simpl.SimpleThreadPool # 线程池类型
5、由于定时任务持久化到数据库里，quartz会在程序启动时自动加载定时任务，所以应用自定义job_info任务表需要有同步操作。比如job_info手动调整了enable状态，其实对于quartz来说是不可见的。
例如：因为某种原因停止了应用，并且手动将job_info里的任务设置为false或者删除，但是quartz自管理里表里还有任务，所以定时任务还是会在应用启动侯开启。所以需要在程序启动检测所有有效任务，并删除无效任务，
并且，不要手动去删除job_info里定时任务，否则需要手动删除QRTZ_系列表里的任务。
public void addSerialJob(JobInfo jobInfo){ // 如果使用了数据库集群或者数据库持久化，则需要手动同步job_info表和qrtz_各类表的同步。 if(!jobInfo.getEnable()){ deleteJob(jobInfo); return; } JobDetail jobDetail = JobBuilder.newJob(QuartzSerialJob.class) .storeDurably() .withIdentity(JOB_NAME + jobInfo.getId()) .build(); CronTrigger cronTrigger = TriggerBuilder.newTrigger() .withIdentity(JOB_NAME + jobInfo.getId()) .startNow() .withSchedule(CronScheduleBuilder.cronSchedule(jobInfo.getCronExpression())) .build(); cronTrigger.getJobDataMap().put(JobConstant.JOB_KEY,jobInfo); try { JobDetail checked = scheduler.getJobDetail(JobKey.jobKey(JOB_NAME + jobInfo.getId())); if(checked==null){ scheduler.scheduleJob(jobDetail,cronTrigger); } } catch (SchedulerException e) { log.error("创建定时任务失败："+jobInfo.toString()); e.printStackTrace(); throw new CommonException(StatusCode.ERROR,"创建定时任务失败:"+jobInfo.toString()); } }
6、quartz自管理任务表
