Quartz插件与Spring Boot集成方法

要将Quartz插件集成到Spring Boot应用程序中，可以按照以下步骤操作：

1. 添加Quartz依赖：在pom.xml文件中添加Quartz和相关依赖项：

    org.springframework.boot
    spring-boot-starter-quartz

2. 配置Quartz属性：在application.properties文件中添加Quartz相关属性配置，例如：

spring.quartz.job-store-type=jdbc
spring.quartz.properties.org.quartz.scheduler.instanceName=myScheduler
spring.quartz.properties.org.quartz.scheduler.instanceId=AUTO
spring.quartz.properties.org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
spring.quartz.properties.org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
spring.quartz.properties.org.quartz.jobStore.tablePrefix=QRTZ_
spring.quartz.properties.org.quartz.jobStore.isClustered=true
spring.quartz.properties.org.quartz.jobStore.clusterCheckinInterval=20000
spring.quartz.properties.org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
spring.quartz.properties.org.quartz.threadPool.threadCount=10

3. 创建Quartz Job类：编写一个实现Job接口的任务类，实现具体的任务逻辑。

4. 创建JobDetail和Trigger：在Spring配置类中配置JobDetail和Trigger，并将它们与Quartz Scheduler集成。

@Autowired
private ApplicationContext applicationContext;

@Bean
public JobDetail jobDetail() {
    return JobBuilder.newJob().ofType(MyJob.class)
            .storeDurably()
            .withIdentity("myJob")
            .withDescription("My Job Description")
            .build();
}

@Bean
public Trigger trigger(JobDetail job) {
    return TriggerBuilder.newTrigger()
            .forJob(job)
            .withIdentity("myTrigger")
            .withSchedule(CronScheduleBuilder.cronSchedule("0/30 * * * * ?"))
            .build();
}

@Bean
public Scheduler scheduler(JobDetail job, Trigger trigger) throws SchedulerException {
    StdSchedulerFactory factory = new StdSchedulerFactory();
    factory.initialize(new ClassPathResource("quartz.properties").getInputStream());
    Scheduler scheduler = factory.getScheduler();
    scheduler.setJobFactory(new AutowiringSpringBeanJobFactory(applicationContext));
    scheduler.scheduleJob(job, trigger);
    scheduler.start();
    return scheduler;
}

5. 创建自定义JobFactory：为了能够在Job中使用Spring的依赖注入，需要创建一个自定义的JobFactory类。

public class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware {

    private transient AutowireCapableBeanFactory beanFactory;

    public AutowiringSpringBeanJobFactory(ApplicationContext context) {
        beanFactory = context.getAutowireCapableBeanFactory();
    }

    @Override
    protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
        final Object job = super.createJobInstance(bundle);
        beanFactory.autowireBean(job);
        return job;
    }
}

通过以上步骤，您就可以成功将Quartz插件集成到Spring Boot应用程序中，并使用Quartz来调度任务。
