Quartz+Spring 实现任务监控

标签：quartz   监控 shiro   

Quartz是一个优秀的任务调度框架，完全基于Java实现，功能强大，易于集成，最近在写了一个小项目，算是对之前接触到的技术做一个总结吧，在这个项目中使用Quartz实现对任务的监控，最终实现的效果如图：

添加效果：

目前已经实现了对Quartz任务的动态添加、暂停、恢复、删除等功能，该项目中使用的是CronTrigger，CronTrigger可以配置灵活的时间规则，是和企业级的应用。

JobDetail界面效果图：

对quartz的研究还在继续，项目也做了不少了，暂时真正研究Quartz应该算刚刚开始，还属于新人阶段，还有一些问题需要解决，在此做一个总结，同时也希望志同道合之人指点一二，互相学习，互相进步吧。

项目简介：

项目名称：cube

项目使用的服务器：tomcat

项目框架：Struts+Spring+Hibernate

数据库：Mysql

开发工具：eclipse

前端：easyui

项目模块如图：

上班族一名，只能趁工作之余来写代码，目前只是实现了系统管理和作业监控部分，系统管理整体使用Shiro实现，目前可以控制到Button级别，作业监控使用Quartz实现

Quartz中 quartz-2.1.7\quartz-2.1.7\docs\dbTables 中有我们实现监控所需的表，依照数据库选择

Quartz数据库核心表如下：

下面是Quartz任务监控的具体配置和实现：

Spring配置如下：
