定时任务配置

        最近要做一个定时收邮件上传，跑批的任务。想来想去，用Quartz的开源框架最好了，其他的像java并发这个需要你封装；用Quartz正好被spring封装了，正好我的项目中类似与SSH框架，所以，正好用这个spring-quartz.他有两种方式配置。

       1.继承QuartzJobBean创建作业。采用这种方式时，Quartz的作业与以前的作业有很大的不同：Quartz里作业需要实现Job接口，

而采用这种方式的作业改为继承QuartzJobBean。QuartzJobBean是个抽象类，因此继承该类，要求实现类里的

void executeInternal(JobExecutionContext ctx)throws JobExecutionException方法，该方法正式任务调度的执行体。
