【通切1】Quartz框架的使用

Quartz框架是用于定时执行任务的框架。

需要引入的包为quartz-all-1.5.2.jar

首先是写一个Job类，类似于

public class RouterLogSche implements Job{
    private final static Logger logger = Logger.getLogger(RouterLogSche.class);

	@Override
	public void execute(JobExecutionContext arg0) throws JobExecutionException {
		// TODO Auto-generated method stub
		logger.info("RouterLogScheduler执行定时任务");
		System.out.println("执行任务iiiiiiiiiiii");
	}
    
}

然后是书写调度类，调度类的对象用于调度这个Job类。

形如：

public class InventedNumService {
     public final static Logger logger = Logger.getLogger(InventedNumService.class);
     private static InventedNumService ins = null;
     public InventedNumService getInstance(){
    	 if(ins == null)
    	   ins = new InventedNumService();
    	 return ins;
     }
     public static void setUpInventedNum() throws Exception{
    	 logger.info("测试已经开始...");
    	 SchedulerFactory sche_fac = new StdSchedulerFactory();
    	 try{
    	 Scheduler sche = sche_fac.getScheduler();
    	 JobDetail jobDetail = new JobDetail("jobDetail","jobDetailGroup",InventedNumSche.class);
    	 CronTrigger cronTrigger = new CronTrigger("cronTrigger","triggerGroup");


    	 CronExpression cexp = new CronExpression("0 0/5 * ? * *");
    	 cronTrigger.setCronExpression(cexp);
    	 sche.scheduleJob(jobDetail,cronTrigger);
    	 sche.start();
    	 }catch(SchedulerException e){
    		 e.printStackTrace();
    	 }catch(ParserException e){
    		 e.printStackTrace();
    	 }
     }
}

CronExpression是时间表达式。
