Quartz使用例子

1.這裏的例子使用的是quartz-all-2.1.7.jar,這個jar包依賴log4j-1.2.16.jar,slf4j-api-1.6.1.jar,slf4j-log4j12-1.6.1.jar

2.上代碼

package study.quartz;

import org.quartz.*;
import org.quartz.impl.JobDetailImpl;
import org.quartz.impl.StdSchedulerFactory;

/**
 * Created with IntelliJ IDEA.
 * User: gl
 * Date: 13-6-5
 * Time: 下午7:40
 * ClassDesc:
 * To change this template use File | Settings | File Templates.
 */
public class TestQuartz {
    public static void main(String[] args) throws SchedulerException {
        SchedulerFactory schedulerFactory = new StdSchedulerFactory();
        Scheduler scheduler = schedulerFactory.getScheduler();

        JobDetail jobDetail = JobBuilder.newJob()
                .ofType(HelloJob.class)
                .usingJobData("Test1","Quartz")
                .withIdentity("Test1","Group1")
                .build();//經過JobBuilder構建JobDetailImpl 實例,也能夠直接new JobDetailImpl

        Trigger trigger = TriggerBuilder.newTrigger()
                .withSchedule(CronScheduleBuilder.cronSchedule("0/3 * * * * ?"))
                .forJob("Test1","Group1")       //Trigger找到對應的名稱爲Test1組爲Group1的Job,若是不存在則會在執行scheduler.scheduleJob(jobDetail,trigger);報錯
                .build();//經過TriggerBuilder構建CronTriggerImpl實例,也能夠直接new CronTriggerImpl

        scheduler.scheduleJob(jobDetail,trigger);//任務每3秒觸發一次

        scheduler.start();
    }
}

package study.quartz;

import org.quartz.Job;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

/**
 * Created with IntelliJ IDEA.
 * User: gl
 * Date: 13-6-6
 * Time: 上午9:57
 * ClassDesc:
 * To change this template use File | Settings | File Templates.
 */
public class HelloJob implements Job {
    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        JobDataMap jobDataMap = context.getJobDetail().getJobDataMap();
        String a = (String)jobDataMap.get("Test1");
        System.out.println("Hello " + a);
    }
}

任務的定義比較簡單,只須要implements Job,實現execute方法便可,觸發任務時,execute方法會執行.

示例定義的是一個每三秒執行一次的任務,經過TriggerBuilder構建Trigger實例,也能夠直接經過new方式構建.

這個示例使用的是默認的quartz配置,若是指定配置,能夠編輯一個Properties文件,

schedulerFactory.initialize(props);//初始化指定配置
