环境
最近项目（springmvc+jboss(tomcat)+db2）需要用到定时执行，java 定时任务
java.util.Timer
- Java自带的java.util.Timer类，这个类允许你调度一个java.util.TimerTask任务。使用这种方式可以让你的程序按照某一个频度执行，但不能在指定时间运行。一般用的较少，这篇文章将不做详细介绍。
Quartz
-
使用Quartz，这是一个功能比较强大的的调度器，可以让你的程序在指定时间执行，也可以按照某一个频度执行，配置起来稍显复杂，兼容性比较好。（quartz-all-1.6.1.jar），
需要继承 org.springframework.scheduling.quartz.QuartzJobBean类，配置触发器（SimpleTriggerBean或CronTriggerBean）每隔指定时间则触发一次
Spring-task
- Spring3.0以后自带的task ：scheduledTask，可以将它看成一个轻量级的Quartz，而且使用起来比Quartz简单许多。（spring-support.jar），必须spring3.0以后的版本。
总结
- 如果用spring的话，其自带的task比较好用。这些应用的配置，gogle百度一大把、这里贡献一个 scheduledTask的配置文件（清晰简单）
