Configuration

quartz与Spring相关框架的整合方式有很多种，我们今天采用jobDetail使用Spring Ioc托管方式来完成整合，我们可以在定时任务实例中使用Spring注入注解完成业务逻辑处理

项目内部数据源的方式来设置调度器的jobSotre，官方quartz有两种持久化的配置方案。

第一种：采用quartz.properties配置文件配置独立的定时任务数据源，可以与使用项目的数据库完全独立。
第二种：采用与创建项目统一个数据源，定时任务持久化相关的表与业务逻辑在同一个数据库内。

@Configuration
@EnableScheduling
public class QuartzConfiguration
{
    /**
     * 继承org.springframework.scheduling.quartz.SpringBeanJobFactory
     * 实现任务实例化方式
     */
    public static class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements
            ApplicationContextAware {

        private transient AutowireCapableBeanFactory beanFactory;

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

        /**
         * 将job实例交给spring ioc托管
         * 我们在job实例实现类内可以直接使用spring注入的调用被spring ioc管理的实例
         * @param bundle
         * @return
         * @throws Exception
         */
        @Override
        protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
            final Object job = super.createJobInstance(bundle);
            /**
             * 将job实例交付给spring ioc
             */
            beanFactory.autowireBean(job);
            return job;
        }
    }

    /**
     * 配置任务工厂实例
     * @param applicationContext spring上下文实例
     * @return
     */
    @Bean
    public JobFactory jobFactory(ApplicationContext applicationContext)
    {
        /**
         * 采用自定义任务工厂 整合spring实例来完成构建任务
         * see {@link AutowiringSpringBeanJobFactory}
         */
        AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
        jobFactory.setApplicationContext(applicationContext);
        return jobFactory;
    }

    /**

     * @throws Exception
     */
    @Bean(destroyMethod = "destroy",autowire = Autowire.NO)
    public SchedulerFactoryBean schedulerFactoryBean(JobFactory jobFactory, DataSource dataSource) throws Exception
    {
        SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
        //将spring管理job自定义工厂交由调度器维护
        schedulerFactoryBean.setJobFactory(jobFactory);
        //设置覆盖已存在的任务
        schedulerFactoryBean.setOverwriteExistingJobs(true);
        //项目启动完成后，等待2秒后开始执行调度器初始化
        schedulerFactoryBean.setStartupDelay(2);
        //设置调度器自动运行
        schedulerFactoryBean.setAutoStartup(true);
        //设置数据源，使用与项目统一数据源
        schedulerFactoryBean.setDataSource(dataSource);
        //设置上下文spring bean name
        schedulerFactoryBean.setApplicationContextSchedulerContextKey("applicationContext");
        //设置配置文件位置
        schedulerFactoryBean.setConfigLocation(new ClassPathResource("/quartz.properties"));
        return schedulerFactoryBean;
    }
}

properties

quartz.properties配置文件一定要放在classpath下，放在别的位置有部分功能不会生效。

#调度器实例名称
org.quartz.scheduler.instanceName = quartzScheduler

#调度器实例编号自动生成
org.quartz.scheduler.instanceId = AUTO

#持久化方式配置
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX

#持久化方式配置数据驱动，MySQL数据库
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate

#quartz相关数据表前缀名
org.quartz.jobStore.tablePrefix = QRTZ_

#开启分布式部署
org.quartz.jobStore.isClustered = true
#配置是否使用
org.quartz.jobStore.useProperties = false

#分布式节点有效性检查时间间隔，单位：毫秒
org.quartz.jobStore.clusterCheckinInterval = 20000

#线程池实现类
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool

#执行最大并发线程数量
org.quartz.threadPool.threadCount = 10

#线程优先级
org.quartz.threadPool.threadPriority = 5

#配置为守护线程，设置后任务将不会执行
#org.quartz.threadPool.makeThreadsDaemons=true

#配置是否启动自动加载数据库内的定时任务，默认true
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true

在上面配置中org.quartz.jobStore.class与org.quartz.jobStore.driverDelegateClass是定时任务持久化的关键配置，配置了数据库持久化定时任务以及采用MySQL数据库进行连接，当然这里我们也可以配置其他的数据库，如下所示： PostgreSQL ： org.quartz.impl.jdbcjobstore.PostgreSQLDelegate Sybase : org.quartz.impl.jdbcjobstore.SybaseDelegate MSSQL : org.quartz.impl.jdbcjobstore.MSSQLDelegate HSQLDB : org.quartz.impl.jdbcjobstore.HSQLDBDelegate Oracle : org.quartz.impl.jdbcjobstore.oracle.OracleDelegate

org.quartz.jobStore.tablePrefix属性配置了定时任务数据表的前缀，在quartz官方提供的创建表SQL脚本默认就是qrtz_，在对应的XxxDelegate驱动类内也是使用的默认值，所以这里我们如果修改表名前缀，配置可以去掉。

org.quartz.jobStore.isClustered属性配置了开启定时任务分布式功能，再开启分布式时对应属性org.quartz.scheduler.instanceId 改成Auto配置即可，实例唯一标识会自动生成，这个标识具体生成的内容，我们一会在运行的控制台就可以看到了，定时任务分布式准备好后会输出相关的分布式节点配置信息。

定义Job和执行

同样需要继承org.springframework.scheduling.quartz.QuartzJobBean抽象类实现抽象类内的executeInternal方法

public class XXXXXTimer
    extends QuartzJobBean
{
    /**
     * logback
     */
    static Logger logger = LoggerFactory.getLogger(GoodStockCheckTimer.class);

    @Override
    protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        logger.info("执行库存检查定时任务，执行时间：{}",new Date());
    }
}

定义任务调度器

//任务名称
String name = UUID.randomUUID().toString();
//任务所属分组
String group = GoodStockCheckTimer.class.getName();

CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule("0/30 * * * * ?");
//创建任务
JobDetail jobDetail = JobBuilder.newJob(GoodStockCheckTimer.class).withIdentity(name,group).build();
//创建任务触发器
Trigger trigger = TriggerBuilder.newTrigger().withIdentity(name,group).withSchedule(scheduleBuilder).build();
//将触发器与任务绑定到调度器内
scheduler.scheduleJob(jobDetail, trigger);
