本文介绍了如何在Spring Boot项目中使用Quartz框架进行定时任务调度，并展示了如何通过AutowireCapableBeanFactory实现Job实例的依赖注入。内容包括引入Quartz依赖、自定义JobFactory及创建和配置调度任务。

1、引入pom

 <!-- quartz -->
            <dependency>
                <groupId>org.quartz-scheduler</groupId>
                <artifactId>quartz</artifactId>
                <version>2.2.3</version>
            </dependency>
            <dependency>
                <groupId>org.quartz-scheduler</groupId>
                <artifactId>quartz-jobs</artifactId>
                <version>2.2.3<</version>
            </dependency>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context-support</artifactId>
                <version>4.1.6.RELEASE</version>
            </dependency>

2、

@Component
public class MyJobFactory extends AdaptableJobFactory {

    /**
     * AutowireCapableBeanFactory接口是BeanFactory的子类
     * 可以连接和填充那些生命周期不被Spring管理的已存在的bean实例
     * 具体请参考：http://blog.youkuaiyun.com/iycynna_123/article/details/52993542
     */
    @Autowired
    private AutowireCapableBeanFactory capableBeanFactory;

    /**
     * 创建Job实例
     *
     * @param bundle
     * @return
     * @throws Exception
     */
    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
        // 实例化对象
        Object jobInstance = super.createJobInstance(bundle);
        // 进行注入（Spring管理该Bean）
        capableBeanFactory.autowireBean(jobInstance);
        //返回对象
        return jobInstance;
    }
}

@Configuration

    @Autowired

        SchedulerFactoryBean factoryBean = new SchedulerFactoryBean();
        factoryBean.setJobFactory(myJobFactory);
        return factoryBean;
    }

    @Bean(name = "scheduler")
    public Scheduler exeScheduler() throws SchedulerException {
        // 1. 创建scheduler，调度器  核心组件
        Scheduler scheduler = schedulerFactoryBean().getScheduler();
        Trigger trigger = TriggerBuilder.newTrigger()
            // 定义name/group
            .withIdentity("trigger1", "group1")
            .startNow()//一旦加入scheduler，立即生效，即开始时间
            .withSchedule(SimpleScheduleBuilder.simpleSchedule()
                .withIntervalInSeconds(2)
                .repeatForever())//一直执行下去
            //.endAt(new GregorianCalendar(2023,9,19,9,59,10).getTime())//设置最终停止时间
            .build();

        // 3. 创建JobDetail，JobBuilder（任务）
        JobDetail jobDetail = JobBuilder.newJob(MyJob.class)
            // 任务的名字和组
            .withIdentity("job04", "group04")
            // 任务中的数据和值
            .usingJobData("lierlin", "hello word ~~~")
            .build();

        // 4. 注册 JobDetail 和 Trigger
        scheduler.scheduleJob(jobDetail, trigger);//将任务和触发器注册到调度器
        scheduler.start();

        return scheduler;
    }
