Spring整合Quartz定时任务 在集群、分布式系统中的应用(Mysql数据库环境)

单个Quartz实例能给予你很好的Job调度能力，但它不能满足典型的企业需求，如可伸缩性、高可靠性满足。假如你需要故障转移的能力并能运行日益增多的 Job，Quartz集群势必成为你应用的一部分了。使用 Quartz 的集群能力可以更好的支持你的业务需求，并且即使是其中一台机器在最糟的时间崩溃了也能确保所有的 Job 得到执行。
Quartz 中集群如何工作
一个 Quartz 集群中的每个节点是一个独立的 Quartz 应用，它又管理着其他的节点。意思是你必须对每个节点分别启动或停止。不像许多应用服务器的集群，独立的 Quartz 节点并不与另一其的节点或是管理节点通信。Quartz 应用是通过数据库表来感知到另一应用的。
图：表示了每个节点直接与数据库通信，若离开数据库将对其他节点一无所知
创建Quartz数据库表
因为Quartz 集群依赖于数据库，所以必须首先创建Quartz数据库表。Quartz 包括了所有被支持的数据库平台的 SQL 脚本。解压 Quartz 分发包后的目录，在 /docs/dbTables 目录下找到那些 SQL 脚本。
总共11张表，不同版本，表个数可能不同。数据库为mysql，用tables_mysql_innodb.sql创建数据库表。
#
# In your Quartz properties file, you\'ll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate

# I didn\'t see this anywhere, so I thought I\'d post it here. This is the script from Quartz to create the tables in a MySQL database, modified to use INNODB instead of MYISAM.

配置 Quartz 使用集群
1.配置节点的 quartz.properties 文件
#============================================================== #Configure Main Scheduler Properties #============================================================== org.quartz.scheduler.instanceName = defaultScheduler org.quartz.scheduler.instanceId = AUTO #============================================================== #Configure JobStore #============================================================== org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate org.quartz.jobStore.tablePrefix = QRTZ_ org.quartz.jobStore.isClustered = true org.quartz.jobStore.clusterCheckinInterval = 20000 org.quartz.jobStore.dataSource = myDS org.quartz.jobStore.maxMisfiresToHandleAtATime = 1 org.quartz.jobStore.misfireThreshold = 120000 org.quartz.jobStore.txIsolationLevelSerializable = true #============================================================== #Configure ThreadPool #============================================================== org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool org.quartz.threadPool.threadCount = 10 org.quartz.threadPool.threadPriority = 5 org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true #============================================================== #Skip Check Update #update:true #not update:false #============================================================== org.quartz.scheduler.skipUpdateCheck = true #============================================================================ # Configure Plugins #============================================================================ org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingJobHistoryPlugin org.quartz.plugin.shutdownhook.class = org.quartz.plugins.management.ShutdownHookPlugin org.quartz.plugin.shutdownhook.cleanShutdown = true
org.quartz.scheduler.instanceName 属性可为任何值，用在 JDBC JobStore 中来唯一标识实例，但是所有集群节点中必须相同。
org.quartz.scheduler.instanceId 属性为 AUTO即可，基于主机名和时间戳来产生实例 ID。
org.quartz.jobStore.class 属性为 JobStoreTX，将任务持久化到数据中。因为集群中节点依赖于数据库来传播 Scheduler 实例的状态，你只能在使用 JDBC JobStore 时应用 Quartz 集群。这意味着你必须使用 JobStoreTX 或是 JobStoreCMT 作为 Job 存储；你不能在集群中使用 RAMJobStore。
org.quartz.jobStore.isClustered 属性为 true，你就告诉了 Scheduler 实例要它参与到一个集群当中。这一属性会贯穿于调度框架的始终，用于修改集群环境中操作的默认行为。
org.quartz.jobStore.clusterCheckinInterval 属性定义了Scheduler 实例检入到数据库中的频率(单位：毫秒)。Scheduler 检查是否其他的实例到了它们应当检入的时候未检入；这能指出一个失败的 Scheduler 实例，且当前 Scheduler 会以此来接管任何执行失败并可恢复的 Job。通过检入操作，Scheduler 也会更新自身的状态记录。clusterChedkinInterval 越小，Scheduler 节点检查失败的 Scheduler 实例就越频繁。默认值是 15000 (即15 秒)。
2.配置applicationContext-quartz.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</bean>

</beans>
dataSource：项目中用到的数据源，里面包含了quartz用到的11张数据库表；
applicationContextSchedulerContextKey： 是org.springframework.scheduling.quartz.SchedulerFactoryBean这个类中把spring上下 文以key/value的方式存放在了SchedulerContext中了，可以用applicationContextSchedulerContextKey所 定义的key得到对应spring 的ApplicationContext；
configLocation：用于指明quartz的配置文件的位置
requestsRecovery
requestsRecovery属性必须设置为 true，当Quartz服务被中止后，再次启动或集群中其他机器接手任务时会尝试恢复执行之前未完成的所有任务。
<bean id="myJobFactory" class="com.xiyinli.Timed.MyJobFactory"></bean>为重写的bean管理工厂类方便定时类service注入bean：
package com.xiyinli.Timed;
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.scheduling.quartz.AdaptableJobFactory;
/**
* Created by Administrator on 2017/8/16 0016.
*/
public class MyJobFactory extends AdaptableJobFactory {
//这个对象Spring会帮我们自动注入进来,也属于Spring技术范畴.
@Autowired
private AutowireCapableBeanFactory capableBeanFactory;
protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
//调用父类的方法
Object jobInstance = super.createJobInstance(bundle);
//进行注入,这属于Spring的技术,不清楚的可以查看Spring的API.
capableBeanFactory.autowireBean(jobInstance);
return jobInstance;
}
}
3.把applicationContext-quartz.xml引入spring, applicationContext-quartz.xml中的dataSource为上面spring-mybatis.xml的bean数据库配置
4. 上面的配置是多任务多定时器，这里以其中的 com.xiyinli.Timed.EmptyVisitOfTodayTimed 为例，其他4个一样编写。
package com.xiyinli.Timed;
import com.xiyinli.mapper.StoreMapper;
import com.xiyinli.service.StoreService;
import org.apache.log4j.Logger;
import org.quartz.DisallowConcurrentExecution;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.PersistJobDataAfterExecution;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.scheduling.quartz.QuartzJobBean;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import javax.annotation.Resource;
/**
* Created by Administrator on 2017/8/2.
*/
@Service
@Transactional
@PersistJobDataAfterExecution
@DisallowConcurrentExecution// 不允许并发执行
public class EmptyVisitOfTodayTimed extends QuartzJobBean {
private Logger log = Logger.getLogger(this.getClass());
private static boolean isRun = false;
@Autowired
private StoreMapper storeMapper;
@Override
protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
if (isRun) {
log.debug("EmptyVisitOfTodayTimed-前一次未执行完,跳过本次任务!");
return;
}
isRun = true;
commissionTask();
isRun = false;
log.debug("执行逻辑-EmptyVisitOfTodayTimed-isRunFinish");
}
//------------------------------------------------------------------------------------------------------------------
public void commissionTask() {
log.debug("凌晨00:10清空每日访问量");
Boolean b = storeMapper.updateTodayVisit();
if (b){
log.debug("正常清空");
}else{
log.debug("清空失败");
}
log.debug("清空每日访问量执行结束");
}
}
5.在最后测试时发现，windows环境运行正常，不是到linux环境下启动时会出现如下错误：
ERROR [org.springframework.web.context.ContextLoader] - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name \'quartzScheduler\' defined ...
Caused by: Java.lang.IllegalStateException: Cannot run without an instance id.
可以尝试使用下面的办法进行解决(一般情况是不能识别主机名)：
先查找主机名复制下来：
[root@iZbp12b0psb88pmxixiwcsZ /]# hostname iZbp12b0psb88pmxixiwcsZ
然后：
[root@iZbp12b0psb88pmxixiwcsZ /]# vi /etc/hosts
编辑如下即可：
