基于quartz的定时任务

1、功能概述：1 首页显示自己添加的定时任务1.1 点击新增可以添加定时任务1.2 任务状态分为：运行中、暂停、已失效，运行中的任务可以删除、编辑、暂停，已失效的任务只可以删除、编辑（重新编辑后任务可以再次运行）2 任性新增界面2.1 编写任务标题2.2 编写提醒内容（提醒内容无字数限制）2.3 提醒时间可以选择详细、每日、每周、每月、cron（类似Linux的cron）2.4 向谁提醒可以选择多人功能实现：1 定时任务持久化如果定时任务不进行持久化配置用户设置的定时任务会保存在内存中，应用重启后定时任务就不存在了。1.1 配置文件各配置参数请自己百度org.quartz.scheduler.in
