动态启动，暂定，添加，删除定时功能，可传参数

动态启动，暂定，添加，删除定时功能，可传参数
Spring中使用Quartz的3种方法（MethodInvokingJobDetailFactoryBean,implements Job,extends QuartzJobBean）
以下介绍一下实现job接口的方法，通过此方法可以动态启动，暂定，添加，删除定时功能，可传参数。
所有数据全部持久化到数据表中，不再需要XML配置文件存储数据。quartz已经封装了持久化方法。数据表用的MYSQL见附件
配置quartz. properties

在这里采用JobStoreTX，将任务持久化到数据中，而不再是简单的内存方式：RAMJobStore
在XML里加入：
在web.xml中添加QuartzInitializerServlet，Quartz为能够在web应用中使用，提供了一个QuartzInitializerServlet和一个QuartzInitializerListener，用于在加载web应用时，对quartz进行初始化。
