楼主小白，目前小公司实习中，进入公司一个月了差不多让我写了个定时任务管理模块。也算入坑了吧！为了纪念这一伟大时刻决定写个我人生中第一篇微博来纪念一下，楼主小白，大神勿喷。只是本着学习和记录的态度写的。
动态QUARTZ 定时任务
Quartz不多解释了好吧。一个我认为功能很强大的定时任务框架（我觉得）。
首先你需要在数据库里建好表（自带的表），嗯，不多也就11张！！！。我用的是2x版本所以是这样的。

上面是2x版本的表。当然有如果你用的是1x的表是不一样的（请去找1x的说明，这篇说明不适合你，立刻就走别耽误工夫）。当时第一次用，纠结了半天。
1.如果你发现什么……column not fount。
2.某个字段未找到，或者未验证。
那么估计你是表的版本用错了，如果是2x版本请复制上面的，从官方文档上粘贴下来的。
以上是数据库建表语句，一共有11张表。但是，你并不一定用的到全部，最主要的有：
1.qrtz_job_detales我的理解管理任务的（最重要的之一）
2.qrtz_trigges管理触发器的（最重要之一）
3.qrtz_scheduler_state调度工厂（最重要之一）
4.qrtz_locks悲观锁（最重要的之一）我并不了解这个的含义但是没有不行，是控制数据线程的大概理解为（主要这个功能暂时没有用到它把这个，这个模块我只是让他跑起来，原理没有深究，因为时间有限啊！希望有大神请给我解释解释，谢谢了！）
5.qrtz_cron_trigger cron触发器表，cron表达式是我用到的定时任务里，来确定时间触发任务的（这个表不是必须的，但是这里主要演示的是这种方式其他方式的请立刻就走，这里不适合你）
6.其他表：我认为如果你是用只的CRON这种方式其他表基本用不到。
说一下包的问题，这是在spring3.0以上版本用到的quartz的包（我的是4.0的）如果你不导入各种错误，你导入错了版本各种错误（版本可能冲突请自行更正）如果你的jar里面有了请不要继续导入。

配置文件。这里说一下我配置遇到的很大问题，我们这个项目是shiro+quartz的版本冲突很严重，一开始是会话session这里出现了问题，我把这里删掉将quartz不放到session没有了问题（暂时），然后因为是maven项目，spring文件和数据库文件没在一个包下导致Data source not found这个错误，解决的方法时quartz重新开个数据源，如下所示，以为我们这个是maven项目分了好多项目包，为了不重复导入文件，将quartz配置写入了spring中，如下所示：另外因为事物中也需要开启对resume读写的权限如下图所示：

调度工厂这个是核心中的核心吧，主要通过反射实例化类中方法，反射不多bb了吧最强大的机制之一（虽然我了解的不是很深。。。。。无奈）。
里面的注释部分当时我打算直接通过service直接操作数据库，但是经理说一般项目都是直接调用空参类型方法，里面怎么用需要自己去配参数，所以注释下面那个直接调用某个包里面的空参方法只是简单的每隔5秒打印出一个字符串。当然你可以自己调用复杂的方法，只要是空参就行。如果不是你需要自行配参数，就是getDeclaredMethod(tm，Interget.class)这样就能调用参数使int类型或者Integer方法了。即使是空参方法执行的功能也有很多需要你自己去写。

还会有其他的总结，一路坚持吧！
