在 Spring 中将 bean 引用注入到 Quartz 作业中？

Question

新手上路，请多包涵

我设法在 Spring 中使用 JobStoreTX 持久存储来配置和安排 Quartz 作业。我不使用 Spring 的 Quartz 作业，因为我需要在运行时动态安排它们，我发现所有将 Spring 与 Quartz 集成的示例都是在 Spring 配置文件中对 shcedules 进行硬编码……无论如何，这是如何我安排工作：

 JobDetail emailJob = JobBuilder.newJob(EMailJob.class)
.withIdentity("someJobKey", "immediateEmailsGroup")
.storeDurably()
.build();

SimpleTrigger trigger = (SimpleTrigger) TriggerBuilder.newTrigger()
.withIdentity("someTriggerKey", "immediateEmailsGroup")
.startAt(fireTime)
.build();

// pass initialization parameters into the job
emailJob.getJobDataMap().put(NotificationConstants.MESSAGE_PARAMETERS_KEY,       messageParameters);
emailJob.getJobDataMap().put(NotificationConstants.RECIPIENT_KEY, recipient);

if (!scheduler.checkExists(jobKey) && scheduler.getTrigger(triggerKey) != null)     {
// schedule the job to run
Date scheduleTime1 = scheduler.scheduleJob(emailJob, trigger);
}

EMailJob 是一个简单的作业，它使用 Spring 的 JavaMailSenderImpl 类发送电子邮件。

 public class EMailJob implements Job {
@Autowired
private JavaMailSenderImpl mailSenderImpl;

    public EMailJob() {
    }
    public void execute(JobExecutionContext context)
       throws JobExecutionException {
   ....
    try {
        mailSenderImpl.send(mimeMessage);
    } catch (MessagingException e) {
        ....
        throw new JobExecutionException("EMailJob failed: " +  jobKey.getName(), e);
    }

    logger.info("EMailJob finished OK");

}

问题是我需要在我的 EMailJob 类中获取对此类 (JavaMailSenderImpl) 实例的引用。当我尝试像这样注入它时：

 @Autowired
private JavaMailSenderImpl mailSenderImpl;

它没有被注入——引用为 NULL。我假设发生这种情况是因为实例化 EMailJob 类的不是 Spring，而是 Quartz，而 Quartz 对依赖注入一无所知……

那么，有什么方法可以强制进行这种注入吗？

谢谢！

更新 1：@Aaron：这是启动时堆栈跟踪的相关部分，它显示了 EMailJob 被实例化了两次：

更新 #2：@Ryan：

我尝试使用 SpringBeanJobFactory 如下：

     <bean id="jobFactoryBean" class="org.springframework.scheduling.quartz.SpringBeanJobFactory">
</bean>

<bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="configLocation" value="classpath:spring/quartz.properties"/>
        <property name="jobFactory" ref="jobFactoryBean"/>
</bean>

我修改了我的主类以从这个工厂获取调度程序，而不是 Quartz’：

     @PostConstruct
public void initNotificationScheduler() {
    try {
        //sf = new StdSchedulerFactory("spring/quartz.properties");
        //scheduler = sf.getScheduler();

        scheduler = schedulerFactoryBean.getScheduler();
        scheduler.start();
            ....

但是当我运行应用程序时 - 出现错误，请参见下文。这是 Spring startup 的堆栈跟踪。似乎 Scheduler 本身创建得很好，但是当它试图实例化我的 EMailJob 时出现错误：

您可以使用这个 SpringBeanJobFactory 使用 spring 自动自动装配石英对象：

 import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;

public final class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements
    ApplicationContextAware {

    private transient AutowireCapableBeanFactory beanFactory;

    @Override
    public void setApplicationContext(final 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;
    }
}

然后，将其附加到您的 SchedulerBean （在本例中，使用 Java-config）：

 @Bean
public SchedulerFactoryBean quartzScheduler() {
    SchedulerFactoryBean quartzScheduler = new SchedulerFactoryBean();

    ...

    AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
    jobFactory.setApplicationContext(applicationContext);
    quartzScheduler.setJobFactory(jobFactory);

    ...

    return quartzScheduler;
}

为我工作，使用 spring-3.2.1 和 quartz-2.1.6。
