我的思路

第一步:添加依赖

<!--quartz依赖-->
<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>2.2.3</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
</dependency>
<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz-jobs</artifactId>
    <version>2.2.3</version>
</dependency>

第二步:创建数据表

第三步:java代码实现

#quartz集群配置
#调度标识名 集群中每一个实例都必须使用相同的名称
org.quartz.scheduler.instanceName=DefaultQuartzScheduler
#ID设置为自动获取 每一个必须不同
org.quartz.scheduler.instanceId=AUTO
org.quartz.scheduler.makeSchedulerThreadDaemon=true
#线程池的实现类(一般使用SimpleThreadPool即可满足需求)
org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
#指定在线程池里面创建的线程是否是守护线程
org.quartz.threadPool.makeThreadsDaemons=true
#指定线程数,至少为1(无默认值)
org.quartz.threadPool.threadCount:20
#设置线程的优先级(最大为java.lang.Thread.MAX_PRIORITY 10,最小为Thread.MIN_PRIORITY 1,默认为5)
org.quartz.threadPool.threadPriority:5
#数据保存方式为数据库持久化
org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
#数据库代理类,一般org.quartz.impl.jdbcjobstore.StdJDBCDelegate可以满足大部分数据库
org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#表的前缀,默认QRTZ_
org.quartz.jobStore.tablePrefix=QRTZ_
#是否加入集群
org.quartz.jobStore.isClustered=true
# 信息保存时间 默认值60秒
org.quartz.jobStore.misfireThreshold=25000
