SpringBoot整合Quartz(二)-持久化到MySQL

计划：(从Quartz的属性、方法、配置文件、配置类、持久化、集群等几个方面，写一些心得)

在上一篇 SpringBoot整合Quartz(一)-简单介绍Demo 中，简单介绍了 Quartz 框架所需的依赖、常用属性、方法和配置。

这里我们将生成的 Job、Trigger 持久化到 MySQL 数据库中。

Quartz

1.修改quartz.properties配置文件

主要是将存储方式从 RAMJobStore 改为 JobStoreTX。
从名称能看出，默认的 RAMJobStore 是存储在内存中的，当项目异常重启后，任务就随内存消失了。

# 固定前缀org.quartz
# 主要分为scheduler、threadPool、jobStore、plugin等部分
#
#
org.quartz.scheduler.instanceName = DefaultQuartzScheduler
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false

# 实例化ThreadPool时，使用的线程类为SimpleThreadPool
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool

# threadCount和threadPriority将以setter的形式注入ThreadPool实例
# 并发个数
org.quartz.threadPool.threadCount = 5
# 优先级
org.quartz.threadPool.threadPriority = 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true

org.quartz.jobStore.misfireThreshold = 5000

# 默认存储在内存中
#org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

#持久化
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX

org.quartz.jobStore.tablePrefix = QRTZ_

org.quartz.jobStore.dataSource = qzDS

org.quartz.dataSource.qzDS.driver = com.mysql.jdbc.Driver

org.quartz.dataSource.qzDS.URL = jdbc:mysql://localhost:3306/study?useUnicode=true&characterEncoding=UTF-8

org.quartz.dataSource.qzDS.user = root

org.quartz.dataSource.qzDS.password = password

org.quartz.dataSource.qzDS.maxConnections = 10

2.导入数据库表

#  
# 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.

3.QuartzConfig

@Configuration
@EnableScheduling
public class SchedulerConfig {

    @Bean(name = "SchedulerFactory")
    public SchedulerFactoryBean schedulerFactoryBean() throws IOException {
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        factory.setQuartzProperties(quartzProperties());
        return factory;
    }

    @Bean
    public Properties quartzProperties() throws IOException {
        PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
        propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
        //在quartz.properties中的属性被读取并注入后再初始化对象
        propertiesFactoryBean.afterPropertiesSet();
        return propertiesFactoryBean.getObject();
    }

    /**
     * quartz初始化监听器
     */
    @Bean
    public QuartzInitializerListener executorListener() {
        return new QuartzInitializerListener();
    }

    /**
     * 通过SchedulerFactoryBean获取Scheduler的实例
     */
    @Bean(name = "Scheduler")
    public Scheduler scheduler() throws IOException {
        return schedulerFactoryBean().getScheduler();
    }
}

4.执行测试

@SpringBootTest
@RunWith(SpringRunner.class)
public class QuartzServiceTest {

    @Test
    public void test() throws SchedulerException {
        // 1. 创建工厂类 SchedulerFactory
        SchedulerFactory factory = new StdSchedulerFactory();
        // 2. 通过 getScheduler() 方法获得 Scheduler 实例
        Scheduler scheduler = factory.getScheduler();

        // 3. 使用上文定义的 HelloJob
        JobDetail jobDetail = JobBuilder.newJob(HelloJob.class)
                //job 的name和group
                .withIdentity("jobName", "jobGroup")
                .build();

        //3秒后启动任务
        Date statTime = new Date(System.currentTimeMillis() + 3000);

        // 4. 启动 Scheduler
        scheduler.start();

        // 5. 创建Trigger
        //使用SimpleScheduleBuilder或者CronScheduleBuilder
        Trigger trigger = TriggerBuilder.newTrigger()
                .withIdentity("jobTriggerName", "jobTriggerGroup")
                .withSchedule(CronScheduleBuilder.cronSchedule("0/2 * * * * ?")) //两秒执行一次
                .build();

        // 6. 注册任务和定时器
        scheduler.scheduleJob(jobDetail, trigger);

    }
}

打开数据库，我们能看到触发器Trigger、任务Job等。
