【Quartz】Spring Boot使用properties文件配置Quartz

（1）在resource目录下新建quartz.properties文件

#============================================================================
# 基础配置
#============================================================================
org.quartz.scheduler.instanceName = JobScheduler
org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false

#============================================================================
# 调度器线程池配置
#============================================================================
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 20
org.quartz.threadPool.threadPriority = 5
org.quartz.jobStore.misfireThreshold = 60000

#============================================================================
# Configure JobStore 作业存储配置
#============================================================================
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.tablePrefix = QRTZ_
org.quartz.jobStore.dataSource = qzDS

org.quartz.jobStore.isClustered = true
org.quartz.jobStore.clusterCheckinInterval = 15000

#============================================================================
# JDBC
#============================================================================
org.quartz.dataSource.qzDS.driver = com.mysql.jdbc.Driver
org.quartz.dataSource.qzDS.URL = jdbc:mysql://localhost:3306/job_scheduler?useUnicode=true&characterEncoding=UTF-8&useSSL=false
org.quartz.dataSource.qzDS.user = ****************
org.quartz.dataSource.qzDS.password = **************
org.quartz.dataSource.qzDS.maxConnections = 5
org.quartz.dataSource.qzDS.validationQuery = select 0 from dual

关于quartz配置的详情，参见官方文档。
