的全部属性如下图：
详解：
applicationContextSchedulerContextKey
Register ApplicationContext in Scheduler context.
从Scheduler上下文中获取ApplicationContext, 通过其指定的key获取。
startupDelay
延迟秒
overwriteExistingJobs
重写已存在的任务（我认为会更新数据库）
dataSource
设置数据源
configLocation
设置配置文件例如：classpath:quartz/quartz.properties
exposeSchedulerInRepository
监控
taskExecutor
执行器
triggers
触发器
