quartz入门简单实例

1.配置文件quartz.properties，放在classpath下（即src下）
最基本配置

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool    
org.quartz.threadPool.threadCount = 3    
org.quartz.threadPool.threadPriority = 5 

2.job实例HelloJob.java

import java.util.Date;  
import org.slf4j.Logger;  
import org.slf4j.LoggerFactory;  
import org.quartz.Job;  
import org.quartz.JobExecutionContext;  
import org.quartz.JobExecutionException;  
  
public class HelloJob implements Job {  
  
    private static Logger _log = LoggerFactory.getLogger(HelloJob.class);  
     
    public HelloJob() {  
          
    }  
     
    public void execute(JobExecutionContext context)  
        throws JobExecutionException {  
          
        _log.error(" 咫尺天涯: " + new Date());  
        System.out.println("saaaaaaaaaaaaaadfafd");
          
    }  
}  

3.测试代码SimpleExample.java

import static org.quartz.JobBuilder.newJob;  
import static org.quartz.TriggerBuilder.newTrigger;  
import static org.quartz.DateBuilder.*;  
import java.util.Date;  
import org.quartz.JobDetail;  
import org.quartz.Scheduler;  
import org.quartz.SchedulerFactory;  
import org.quartz.Trigger;  
import org.quartz.impl.StdSchedulerFactory;  
import org.slf4j.Logger;  
import org.slf4j.LoggerFactory;  
public class SimpleExample {  
  
    private static Logger log = LoggerFactory.getLogger(SimpleExample.class);  
  
    public void run() throws Exception {  
        // 通过SchedulerFactory获取一个调度器实例  
        SchedulerFactory sf = new StdSchedulerFactory();      
          
        Scheduler sched = sf.getScheduler();  
          
        Date runTime = evenMinuteDate(new Date());  
          
        // 通过过JobDetail封装HelloJob，同时指定Job在Scheduler中所属组及名称，这里，组名为group1，而名称为job1。  
        JobDetail job = newJob(HelloJob.class).withIdentity("job1", "group1").build();  
  
        // 创建一个SimpleTrigger实例，指定该Trigger在Scheduler中所属组及名称。  
        // 接着设置调度的时间规则.当前时间运行  
        Trigger trigger = newTrigger().withIdentity("trigger1", "group1").startAt(runTime).build();  
  
        // 注册并进行调度  
        sched.scheduleJob(job, trigger);  
  
        // 启动调度器  
        sched.start();  
  
        try {  
            //当前线程等待65秒  
            Thread.sleep(65L * 1000L);  
        } catch (Exception e) {  
              
        }  
          
        //调度器停止运行  
        sched.shutdown(true);  
          
        log.error("结束运行。。。。");  
          
    }  
  
    public static void main(String[] args) throws Exception {  
        SimpleExample example = new SimpleExample();  
        example.run();  
    }  
}
