Quartz的任务的临时启动和暂停和恢复
在项目中需要手动启停某些服务，那么需要有一个控制这些任务的类。由于任务是有Quartz控制的，我们只需要通过Quartz的相关的API实现相关的功能即可。
个人例子：
package com.tempus.b2gs.scheduler;import org.quartz.Scheduler;import org.quartz.SchedulerException;import org.springframework.beans.BeansException;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;import org.springframework.scheduling.quartz.CronTriggerBean;public class SchedulerController implements ApplicationContextAware{private ApplicationContext context;@Overridepublic void setApplicationContext(ApplicationContext context)throws BeansException{this.context = context;}/** * 方法描述: 更改任务时间 * 作 者： peng.xiao * 日 期： 2014-2-16-下午4:56:04 * @param triggerName * @param cronExper * @throws Exception * 返回类型： void*/public void changeTrigger(String triggerName, String cronExper) throws Exception{Scheduler scheduler = (Scheduler)this.context.getBean("startQuertz");CronTriggerBean trigger = (CronTriggerBean)scheduler.getTrigger(triggerName, Scheduler.DEFAULT_GROUP);trigger.setCronExpression(cronExper);scheduler.rescheduleJob(triggerName, Scheduler.DEFAULT_GROUP, trigger);}/** * 方法描述: 暂停任务 * 作 者： peng.xiao * 日 期： 2014-2-16-下午4:56:16 * @param jobName * @throws Exception * 返回类型： void*/public void pauseJob(String jobName) throws Exception{jobName = jobName.trim();Scheduler scheduler = (Scheduler)this.context.getBean("startQuertz");scheduler.pauseJob(jobName, Scheduler.DEFAULT_GROUP);}/** * 方法描述: 恢复任务 * 作 者： peng.xiao * 日 期： 2014-2-16-下午4:56:27 * @param jobName * @throws SchedulerException * 返回类型： void*/public void resumeJob(String jobName) throws SchedulerException{Scheduler scheduler = (Scheduler)this.context.getBean("startQuertz");scheduler.resumeJob(jobName, Scheduler.DEFAULT_GROUP);}}
