quartz集群分布式(并发)部署解决方案-Spring

项目中使用分布式并发部署定时任务，多台跨JVM，按照常理逻辑每个JVM的定时任务会各自运行，这样就会存在问题，多台分布式JVM机器的应用服务同时干活，一个是加重服务负担，另外一个是存在严重的逻辑问题，
比如需要回滚的数据，就回滚了多次，刚好quartz提供很好的解决方案。

集群分布式并发环境中使用QUARTZ定时任务调度，会在各个节点会上报任务，存到数据库中，执行时会从数据库中取出触发器来执行，如果触发器的名称和执行时间相同，则只有一个节点去执行此任务。

如果此节点执行失败，则此任务则会被分派到另一节点执行，中途也会自动检查失效的定时调度，发现不成功的，其他节点立马接过来继续完成定时任务。对应的定时任务调度表比较多，有11个。
此方法是结合Spring与quartz，实际解决方案如下：

真实运行的业务类：ReleaseQtyAndUpdateOrderStatusSchedule.java
应为要持久化等特性操作,需要继承 QuartzJobBean
由于要被持久化,所以不能存放xxxxManager类似对象,
只能从每次从QuartzJobBean注入的ApplicationContext 中去取出
继承QuartzJobBean，实现方法executeInternal

package com.dennis.walking.api.web.schedule;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.quartz.QuartzJobBean;
import org.springframework.stereotype.Component;
import com.dennis.walking.api.service.OrderService;


@Component
public class ReleaseQtyAndUpdateOrderStatusSchedule extends QuartzJobBean {
	
	private Log log = LogFactory.getLog(this.getClass());
	
	@Autowired
	OrderService orderService;
	
	    
	protected void executeInternal(JobExecutionContext arg0)
			throws JobExecutionException {
		log.info("dennis test execute schedule start ");
		try {
			orderService.releaseQtyAndUpdateOrderStatus();
		} catch (Exception e) {
			e.printStackTrace();
			log.error("execute ReleaseQtyAndUpdateOrderStatus schedule error:"
					+ e.getMessage());
		}
		log.info("dennis test exxcute schedule end");
	}
}

持久化数据：PersistableCronTriggerFactoryBean.java 保存数据到数据库中

package com.dennis.walking.api.web.schedule;

import org.springframework.scheduling.quartz.CronTriggerFactoryBean;
import org.springframework.scheduling.quartz.JobDetailAwareTrigger;

/**
 * Needed to set Quartz useProperties=true when using Spring classes, because
 * Spring sets an object reference on JobDataMap that is not a String
 * 
 * @see http://site.trimplement.com/using-spring-and-quartz-with-jobstore-properties
 *      /
 * @see http
 *      ://forum.springsource.org/showthread.php?130984-Quartz-error-IOException
 */
public class PersistableCronTriggerFactoryBean extends CronTriggerFactoryBean {
	@Override
	public void afterPropertiesSet() {
		super.afterPropertiesSet();
		System.out.println("PersistableCronTriggerFactoryBean-------------------");
		// Remove the JobDetail element
		getJobDataMap().remove(JobDetailAwareTrigger.JOB_DETAIL_KEY);
	}
}

###AutowiringSpringBeanJobFactory.java### 使用spring的 bean文件时，需要使用此类

package com.dennis.walking.api.web.schedule;

import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;

/**
 * Autowire Quartz Jobs with Spring context dependencies
 * 
 * @see http
 *      ://stackoverflow.com/questions/6990767/inject-bean-reference-into-a-quartz
 *      -job-in-spring/15211030#15211030
 */
public final class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory
		implements ApplicationContextAware {

	private transient AutowireCapableBeanFactory beanFactory;

	public void setApplicationContext(final ApplicationContext context) {
		beanFactory = context.getAutowireCapableBeanFactory();
	}

	@Override
	protected Object createJobInstance(final TriggerFiredBundle bundle)
			throws Exception {
		final Object job = super.createJobInstance(bundle);
		beanFactory.autowireBean(job);
		System.out.println("AutowiringSpringBeanJobFactory-------------------");
		return job;
	}
}

Quartz是一个开放源码项目，专注于任务调度器，提供了极为广泛的特性如持久化任务，集群和分布式任务等。 Quartz核心是调度器，还采用多线程管理。

1.持久化任务：当应用程序停止运行时，所有调度信息不被丢失，当你重新启动时，调度信息还存在，这就是持久化任务（保存到数据库表中）。

2.集群和分布式处理：当在集群环境下，当有配置Quartz的多个客户端时（节点），采用Quartz的集群和分布式处理时，我们要了解几点好处
1) 一个节点无法完成的任务，会被集群中拥有相同的任务的节点取代执行。
2） Quartz调度是通过触发器的类别来识别不同的任务，在不同的节点定义相同的触发器的类别，这样在集群下能稳定的运行，一个节点无法完成的任务，会被集群中拥有相同的任务的节点取代执行。
3）分布式体现在当相同的任务定时在一个时间点，在那个时间点，不会被两个节点同时执行。

Quartz的 Task（11 张表）实例化采用数据库存储，基于数据库引擎及 High-Available 的策略（集群的一种策略）自动协调每个节点的 Quartz。
