初识Quartz

首先从Quartz官网上获得相应的jar包，Quartz package包含了许多jar文件，quartz-all-xxx.jar是Quartz的主要的library。获得jar包后引用到自己的工程里（我是把jar下载到我的本地Maven库中）

<dependency>
				<groupId>org.quartz-scheduler</groupId>
				<artifactId>quartz</artifactId>
				<version>${quartz.version}</version>
			</dependency>
			<dependency>
				<groupId>org.quartz-scheduler</groupId>
				<artifactId>quartz-oracle</artifactId>
				<version>${quartz.version}</version>
			</dependency>
			<dependency>
				<groupId>org.quartz-scheduler</groupId>
				<artifactId>quartz-weblogic</artifactId>
				<version>${quartz.version}</version>
			</dependency>

引完jar包，开始我们第一个Quartz的小Demo：首先我们需要定义我们自己的Job

public class MyJob implements Job {
	private Logger logger = LoggerFactory.getLogger(MyJob.class);
	public MyJob(){
		
	}
	@Override
	public void execute(JobExecutionContext arg0) throws JobExecutionException {
		logger.info("my job Start ... ..."+new Date());
	}

}

然后定义scheduler 和trigger 来完成我们Quartz的小Demo

try {
			logger.info("------------------initializing-----------------");
			SchedulerFactory factory = new StdSchedulerFactory();
			Scheduler scheduler = factory.getScheduler();
			logger.info("-------------------initialize complete----------");
			//computer a time that is on the next round time
			Date runTime = DateBuilder.evenMinuteDate(new Date());
			logger.info("-------------------scheduling job---------------");
			//define a Job and tie it to our MyJob class
			JobDetail job = JobBuilder.newJob(MyJob.class)
				.withIdentity("job1", "group1")
				.build();
			//Trigger the job to run on the next round time
			Trigger trigger = TriggerBuilder.newTrigger()
				.withIdentity("trigger1", "group1")
				.startAt(runTime)
				.build();
			//Tell quartz to schedule the job using our trigger
			scheduler.scheduleJob(job, trigger);
			logger.info(job.getKey()+"run at :"+runTime);
			//Start up the scheduler (nothing can actually run until the scheduler  has bean started)
			scheduler.start();
			logger.info("-------------------started Scheduler-------------");
			//wait the scheduler so long enough so that the scheduler as an opportunity to run the job
			logger.info("------------------waiting 65 seconds...----------");
			try{
				//wait the 65 seconds to show job
				Thread.sleep(65L*1000L);
				//execute ...
			}catch (Exception e) {

			}
			//shutdown the scheduler 
			logger.info("----------------shutting down ----------------");
			scheduler.shutdown(true);
			logger.info("----------------shutdown completed------------");
			
		} catch (SchedulerException e) {
			e.printStackTrace();
		}

处理结果：

哈哈 成功了...
