使用quartz数据库锁实现定时任务的分布式部署

使用quartz数据库锁实现定时任务的分布式部署

，1.根据项目引用的quartz依赖版本，确定下载的quartz-distribution安装包，我项目引用的信息如下图所示；

2.解压，在\quartz-2.2.3-distribution\quartz-2.2.3\docs\dbTables路径下，寻找项目中使用的数据库类型对应的脚本文件，我用的是***，脚本信息如下；

3.建好表后，开始写java代码了，首先是2个配置文件，quartz.properties和spring-quartz.xml，其中spring-quartz.xml要随项目加载启动，可以放在spring启动文件里面或者通过listener启动。

然后在applicationContext-bean.xml里面设置需要启动加载的xml

quartz.properties：

#============================================================================# Configure JobStore# Using Spring datasource in quartzJobsConfig.xml# Spring uses LocalDataSourceJobStore extension of JobStoreCMT#============================================================================org.quartz.jobStore.useProperties=true#quartz存储任务相关数据的表的前缀org.quartz.jobStore.tablePrefix = QRTZ_#是否启用集群，启用，改为true,注意：启用集群后，必须配置数据源，否则quartz调度器会初始化失败org.quartz.jobStore.isClustered = true#集群中服务器相互检测间隔，每台服务器都会按照下面配置的时间间隔往服务器中更新自己的状态，如果某台服务器超过以下时间没有checkin，调度器就会认为该台服务器已经down掉，不会再分配任务给该台服务器org.quartz.jobStore.clusterCheckinInterval = 5000#表示如果某个任务到达执行时间，而此时线程池中没有可用线程时，任务等待的最大时间，如果等待时间超过下面配置的值(毫秒)，本次就不在执行，而等待下一次执行时间的到来，可根据任务量和负责程度来调整org.quartz.jobStore.misfireThreshold = 60000org.quartz.jobStore.txIsolationLevelReadCommitted = true#实现集群时，任务的存储实现方式，org.quartz.impl.jdbcjobstore.JobStoreTX表示数据库存储org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTXorg.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate#============================================================================# Configure Main Scheduler Properties# Needed to manage cluster instances#============================================================================#集群中每台服务器自己的id，AUTO表示自动生成org.quartz.scheduler.instanceId=AUTO#配置集群时，quartz调度器的id，由于配置集群时，只有一个调度器，必须保证每个服务器该值都相同，可以不用修改，只要每个ams都一样就行org.quartz.scheduler.instanceName=MY_CLUSTERED_JOB_SCHEDULERorg.quartz.scheduler.rmi.export = falseorg.quartz.scheduler.rmi.proxy = false#============================================================================# Configure ThreadPool#============================================================================#quartz线程池的实现类org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool#quartz线程池中线程数，可根据任务数量和负责度来调整org.quartz.threadPool.threadCount = 10#quartz线程优先级org.quartz.threadPool.threadPriority = 5org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true

spring-quartz.xml：

4.编码AutowiringSpringBeanJobFactory类，作用是：使用@autowire来自动装配类

package com.ra.quartz;import org.quartz.spi.TriggerFiredBundle;import org.springframework.beans.BeansException;import org.springframework.beans.factory.config.AutowireCapableBeanFactory;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;import org.springframework.scheduling.quartz.SpringBeanJobFactory;/** * @Auther: lanhao * @Date: 2018/8/14 11:37 * @Description: */public class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware { private transient AutowireCapableBeanFactory beanFactory; public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { beanFactory = applicationContext.getAutowireCapableBeanFactory(); } @Override protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception { Object job = super.createJobInstance(bundle); beanFactory.autowireBean(job); return job; }}

5.编写PersistableCronTriggerFactoryBean类

package com.ra.quartz;import org.springframework.scheduling.quartz.CronTriggerFactoryBean;import java.text.ParseException;/** * @Auther: lanhao * @Date: 2018/8/14 14:06 * @Description: */public class PersistableCronTriggerFactoryBean extends CronTriggerFactoryBean{ @Override public void afterPropertiesSet() throws ParseException { super.afterPropertiesSet(); getJobDataMap().remove(getObject().getJobKey().getName()); }}

6.下面就是具体的job类了，以其中一个例子为类；

UpdateStatusJobs：

package com.ra.quartz.jobs;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.scheduling.quartz.QuartzJobBean;import com.ra.quartz.UpdateStatusQuartz;public class UpdateStatusJobs extends QuartzJobBean{ @Autowired private UpdateStatusQuartz clusterQuartz; @Override protected void executeInternal(JobExecutionContext context) throws JobExecutionException { clusterQuartz.updateStatus(); }}

注：@Autowired注解能用就是因为上面的AutowiringSpringBeanJobFactory类。

UpdateStatusQuartz类就是具体的业务逻辑代码了，里面写的方法全部在job里面调用就行了。

一个定时任务一个job类。
