第一点：

CRON triggers

1. CronTrigger trigger = TriggerBuilder.newTrigger()

2. .withIdentity(name, TRIGGER_GROUP)

3. .withSchedule(

4. CronScheduleBuilder.cronSchedule(time)

5. .withMisfireHandlingInstructionDoNothing())

6. .build();// 触发器名,触发器组,触发器时间设定

withMisfireHandlingInstructionDoNothing(所有的misfire不管，执行下一个周期的任务)

在quartz.properties配置文件中添加：

#这个时间大于10000（10秒）会导致MISFIRE_INSTRUCTION_DO_NOTHING不起作用。

org.quartz.jobStore.misfireThreshold = 1000

第二点：

配置文件中添加:jobStore

org.quartz.scheduler.instanceName = DatartScheduleCluster

org.quartz.threadPool.threadCount = 10
org.quartz.threadPool.threadPriority = 5
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.jobStore.dataSource = myDS
org.quartz.jobStore.useProperties = true
org.quartz.jobStore.misfireThreshold = 1000
org.quartz.jobStore.isClustered = true
org.quartz.jobStore.clusterCheckinInterval = 5000

org.quartz.dataSource.myDS.driver = com.mysql.jdbc.Driver
org.quartz.dataSource.myDS.URL = jdbc:mysql://172.29.60.145:3306:3306/datart?characterEncoding=utf-8&useSSL=false
# mysql8.0+ÒÔÉÏ°æ±¾ÅäÖÃ
# org.quartz.dataSource.myDS.URL=jdbc:mysql://localhost:3306/quartz?characterEncoding=utf-8&useSSL=false&serverTimezone = GMT
org.quartz.dataSource.myDS.user = root
org.quartz.dataSource.myDS.password = 123456
org.quartz.dataSource.myDS.maxConnections = 5
//这个一定要加
spring.quartz.job-store-type= jdbc

第三个pom中添加依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-quartz</artifactId>
</dependency>

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.29</version>
</dependency>
