Quartz 简单实例

Quartz调度简单案例：

前期准备

导入Quartz到项目中，本人是用的Maven，代码如下

<dependency>
     <groupId>org.quartz-scheduler</groupId>
     <artifactId>quartz</artifactId>
     <version>2.2.1</version>
</dependency>

下载地址如下所示：http://www.quartz-scheduler.org/downloads Maven

http://www.quartz-scheduler.org/downloads/destination?name=quartz-2.2.1-distribution.tar.gz&bucket=tcdistributions&file=quartz-2.2.1-distribution.tar.gz jar包直接下载地址

1、定义Job工作类

package com.timerBin.quartz.simple;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class SimpleJob implements Job {
       private static int i=0;
       @Override
       public void execute(JobExecutionContext job) throws JobExecutionException {
          try {
	      System.err.println("开始:"+i);
	      i++;
          } catch (Exception e) {
	      e.printStackTrace();
          }
       }
}

2、简单例子调用Quartz(最基础调用)

package com.timerBin.quartz.simple;

import java.util.Date;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.impl.JobDetailImpl;
import org.quartz.impl.StdSchedulerFactory;
import org.quartz.impl.triggers.SimpleTriggerImpl;

public class SimpleQuartz {
          public static void main(String[] args) {
               runQuartz();
          }
          public static void runQuartz(){
	       try {
			//定义任务 分组名称信息 分组名 如果不设置分组名 是默认分组Default  
			JobDetail jobDetail =  new JobDetailImpl("myJobName","myJobGroupName", SimpleJob.class);
			//定义调度触发器
			SimpleTriggerImpl strigger = new SimpleTriggerImpl("myTiggerName");
			//触发器 从当前时间开始
			strigger.setStartTime(new Date());
			//调用10次
			strigger.setRepeatCount(10);
			//每隔2000毫秒
			strigger.setRepeatInterval(2000);
			//定义调度
			Scheduler scheudle = new StdSchedulerFactory().getScheduler();
			scheudle.scheduleJob(jobDetail, strigger);
			//调度启动
			scheudle.start();
			Thread.currentThread().sleep(1000);
			//调度关闭
			System.err.println("关闭  ");
			scheudle.shutdown();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

3、包含日历的Quartz简单调用例子

package com.timerBin.quartz.simple;

import java.util.GregorianCalendar;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.impl.JobDetailImpl;
import org.quartz.impl.StdSchedulerFactory;
import org.quartz.impl.calendar.AnnualCalendar;
import org.quartz.impl.triggers.SimpleTriggerImpl;
public class SimpleQuartz {
	public static void main(String[] args) {
	    runQuartz();
	}
	public static void runQuartz(){
		try {
			//定义任务 分组名称信息 分组名 如果不设置分组名 是默认分组Default  
			JobDetail jobDetail =  new JobDetailImpl("myJobName","myJobGroupName", SimpleJob.class);
			//定义日历集合
			AnnualCalendar holidays = new AnnualCalendar();
			//定义日历   默认获得当前时间   也可以根据构造方法定义
			GregorianCalendar calendar = new GregorianCalendar();
			//calendar.set(1, 2015);   年
			//calendar.set(2, 1);      月
			//calendar.set(5, 14);     日
			//将日志添加到几何中  false 不排除  true 排除
			 holidays.setDayExcluded(calendar, false);
			//定义调度
			Scheduler scheudle = new StdSchedulerFactory().getScheduler();
			scheudle.addCalendar("myCalendars", holidays, false, false);
			//定义调度触发器
			SimpleTriggerImpl strigger = new SimpleTriggerImpl("myTiggerName");
			//将日历添加到调度
			strigger.setCalendarName("myCalendars");
			//触发器 从日历中的当前时间开始
			strigger.setStartTime(calendar.getTime());
			//调用10次
			strigger.setRepeatCount(10);
			//每隔2000毫秒
			strigger.setRepeatInterval(2000);
			scheudle.scheduleJob(jobDetail, strigger);
			//调度启动
			scheudle.start();
			Thread.currentThread().sleep(1000);
			//调度关闭
			System.err.println("关闭  ");
			scheudle.shutdown();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

4、将调度任务状态信息保存到数据库

1)下载调度数据库表结构

下载地址：http://www.quartz-scheduler.org/downloads/destination?name=quartz-2.2.1-distribution.tar.gz&bucket=tcdistributions&file=quartz-2.2.1-distribution.tar.gz

所在路径：quartz-2.2.1\docs\dbTables\xxxx.sql

2)在相应数据库中执行sql文件

3)在项目的src路径下创建quartz.properties文件，内容可如下所示(Mysql)：

org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.tablePrefix=QRTZ_
org.quartz.jobStore.dataSource=mySource
org.quartz.dataSource.mySource.driver=com.mysql.jdbc.Driver
org.quartz.dataSource.mySource.URL=jdbc:mysql://xxx.xxx.xxx.xxx:3306/test
org.quartz.dataSource.mySource.user=root
org.quartz.dataSource.mySource.password=root1234
org.quartz.dataSource.mySource.maxConnections=10
org.quartz.threadPool.threadCount=1

具体参数参考地址如下所示：http://www.quartz-scheduler.org/generated/2.2.1/html/qs-all/#page/Quartz_Scheduler_Documentation_Set%2Fre-data_quartz_datasource_properties.html

package com.timerBin.quartz.simple;

import java.util.List;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.impl.StdSchedulerFactory;
import org.quartz.JobKey;

public class SimpleDbQuartz {
	
	public static void main(String[] args) {
		runDbQuartz();
	}
	public static void runDbQuartz(){
             try {
		  //定义调度
		  Scheduler scheudle = new StdSchedulerFactory().getScheduler();
		  //获取所有调度的名称
		  List<String> list = scheudle.getJobGroupNames();
		  for(int i=0;i<list.size();i++){
			//根据所有调度名称回复调度
			scheudle.resumeJob(new JobKey(list.get(i)));
		   }
		   //开始调度
		   scheudle.start();
	     } catch (SchedulerException e) {
		e.printStackTrace();
	     }
	}
}

5、在Spring中集成Quartz
