概述
有关quartz的api文档地址:Quartz Enterprise Job Scheduler 1.8.6 API
主要接口目录:
重点看下Job,Scheduler,Trigger,JobDetail几个:
代表任务的类继承Job接口,该接口只有唯一一个方法 execute;当一个任务的触发器启动时,相应的调度器scheduler会调用该任务。
quartz并不保存一个实际的Job类,而是通过允许你定义一个JobDetail取代。
Scheduler代表JobDetails和Triggers的登记表,Scheduler由SchedulerFactory产生。
quartz的配置文件quartzConfig.xml如下:

web.xml文件中加入相应上述加载配置文件路径。
首先定义一个任务的类
