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.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

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。
