Quartz 2.0 发布，开源作业调度框架

近日，Quartz 2.0发布了！Quartz是一个开源的作业调度框架，它完全由Java写成，并设计用于J2SE和J2EE应用中。

Quartz提供了巨大的灵活性而不牺牲简单性。你能够用它来为执行一个作业而创建简单的或复杂的调度。它有很多特征，如：数据库支持，集群，插件，EJB作业预构建，JavaMail及其它，支持cron-like表达式等等。

开发者称该版本是Quartz 史上最卓越的版本，提供了很多一直备受期待的API改进，并保证最大程度的兼容性。

重点新功能：
·Scheduler.clear() method provides convenient (and dangerous!) way to remove all jobs, triggers and calendars from the scheduler.
·Scheduler.scheduleJobs(Map<JobDetail, List<Trigger>> triggersAndJobs, boolean replace) method provides convenient bulk addition of jobs and triggers.
·Scheduler.unscheduleJobs(List<TriggerKey> triggerKeys) method provides convenient bulk unscheduling of jobs.
·Scheduler.deleteJobs(List<JobKey> jobKeys) method provides convenient bulk deletion of jobs (and related triggers).
·Scheduler.checkExists(JobKey jobKey) and Scheduler.heckExists(TriggerKey triggerKey) methods provides convenient way to determine uniqueness of job/trigger keys (as opposed to old have of having to retrieve the job/trigger by name and then check whether the result was null).
