springboot quartz构建定时任务
  • 开发环境
  • Quartz的3个基本要素
  • 如何使用
    • 引入相关依赖
    • resource目录下创建quartz.properties
    • quartz需要用到的表
    • 实体和其他相关类

开发环境

  • jdk：jdk1.8.0_212
  • maven：apache-maven-3.6.2
  • springboot版本：2.2.0

Quartz的3个基本要素

  • Scheduler：调度器。所有的调度都是由它控制。
  • Trigger： 触发器。决定什么时候来执行任务。
  • JobDetail & Job： JobDetail定义的是任务数据，而真正的执行逻辑是在Job中。使用JobDetail Job而不是Job，这是因为任务是有可能并发执行，如果Scheduler直接使用Job，就会存在对同一个Job实例并发访问的问题。而JobDetail & Job 方式，sheduler每次执行，都会根据JobDetail创建一个新的Job实例，这样就可以规避并发访问的问题。

如何使用

resource目录下创建quartz.properties

代码语言：javascript复制
org.quartz.scheduler.instanceName = TestScheduler
org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false
org.quartz.jobStore.tablePrefix = QRTZ_
#org.quartz.jobStore.dataSource = 这项可以不填，我填了启动时候会报错org.quartz.JobPersistenceException: Failed to obtain DB connection from data source 'xxx': java.sql.SQLException: There is no DataSource named 'xxx'
org.quartz.threadPool.threadCount = 5
org.quartz.threadPool.threadPriority = 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread= true
org.quartz.jobStore.misfireThreshold = 5000
org.quartz.jobStore.class= org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass= org.quartz.impl.jdbcjobstore.StdJDBCDelegate
# 在调度流程的第一步，也就是拉取待即将触发的triggers时，是上锁的状态，即不会同时存在多个线程拉取到相同的trigger的情况，也就避免的重复调度的危险。

quartz需要用到的表

可以去quartz官网下载对应版本的包 解压后再对应的dbTables目录下有各种数据库的建表语句

实体和其他相关类

实体：

代码语言：javascript复制
/**
 * @author zjq
 * @date
 * <p>description:实体</p>
 */
@NoArgsConstructor
@AllArgsConstructor
@Builder
@Data
public class JobAndTrigger {
    /**
     * 定时任务名称
     */
    private String jobName;
    /**
     * 定时任务组
     */
    private String jobGroup;
    /**
     * 定时任务全类名
     */
    private String jobClassName;
    /**
     * 触发器名称
     */
    private String triggerName;
    /**
     * 触发器组
     */
    private String triggerGroup;
    /**
     * 重复间隔
     */
    private BigInteger repeatInterval;
    /**
     * 触发次数
     */
    private BigInteger timesTriggered;
    /**
     * cron 表达式
     */
    private String cronExpression;
    /**
     * 时区
     */
    private String timeZoneId;
    /**
     * 定时任务状态
     */
    private String triggerState;
}

job工厂：

代码语言：javascript复制
@Component
public class JobFactory extends AdaptableJobFactory {
    @Autowired
    private AutowireCapableBeanFactory capableBeanFactory;

     @Override
        protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
            //调用父类的方法
            Object jobInstance = super.createJobInstance(bundle);
            //进行注入
            capableBeanFactory.autowireBean(jobInstance);
            return jobInstance;
        }
}

调度器配置： 如果不配置这个启动时候会报错，无法注入org.quartz.Scheduler

代码语言：javascript复制
@Configuration
public class SchedulerConfig implements ApplicationListener<ContextRefreshedEvent> {
    @Autowired
    private JobFactory jobFactory;
    @Autowired
    @Qualifier("dataSource")
    private DataSource primaryDataSource;

    @Override
     public void onApplicationEvent(ContextRefreshedEvent event) {
        System.out.println("任务已经启动..." event.getSource());
    }

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean() throws IOException {
       //获取配置属性
        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();
        //创建SchedulerFactoryBean
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        factory.setQuartzProperties(propertiesFactoryBean.getObject());
        //使用数据源，自定义数据源
        factory.setDataSource(this.primaryDataSource);
        factory.setJobFactory(jobFactory);
        factory.setWaitForJobsToCompleteOnShutdown(true);//这样当spring关闭时，会等待所有已经启动的quartz job结束后spring才能完全shutdown。
        factory.setOverwriteExistingJobs(false);
        factory.setStartupDelay(1);
        return factory;
    }


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


    @Bean
    public QuartzInitializerListener executorListener() {
       return new QuartzInitializerListener();
    }
