任务调度开源框架Quartz动态添加、修改和删除定时任务

Quartz 是个开源的作业调度框架,为在 Java 应用程序中进行作业调度提供了简单却强大的机制。Quartz框架包含了调度器监听、作业和触发器监听。你可以配置作业和触发器监听为全局监听或者是特定 于作业和触发器的监听。Quartz 允许开发人员根据时间间隔(或天)来调度作业。它实现了作业和触发器的多对多关系,还能把多个作业与不同的触发器关联。整合了 Quartz 的应用程序可以重用来自不同事件的作业,还可以为一个事件组合多个作业。并且还能和Spring配置整合使用。Quartz在功能上远远超越了JDK自带 的Timer,很好很强大!好啦,直接上代码:
