在Spring中将bean引用注入Quartz作业?

标签: spring quartz-scheduler inject

我设法在Spring中使用JobStoreTX持久存储来配置和调度Quartz作业。我不使用Spring的Quartz作业,因为我需要在运行时动态调度它们,并且我发现Spring与Quartz集成的所有示例都是对Spring配置文件中的shcedules进行硬编码...无论如何,这里是如何我安排工作:

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是一个简单的工作,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类中获取对此类实例(JavaMailSenderImpl)的引用。当我尝试像这样注入它时:

@Autowired
private JavaMailSenderImpl mailSenderImpl;

未注入 - 引用为NULL。我假设这种情况正在发生,因为实例化EMailJob类不是Spring,而Quartz和Quartz对依赖注入一无所知......

那么,是否有某种方法可以强制进行注射?

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:

谢谢!

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得Scheduler,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 - 获取错误,请参阅下文。这是Spring启动的堆栈跟踪。看起来调度程序本身创建得很好,但是当它试图实例化我的EMailJob时会出现错误:

您可以使用此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,将它附加到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;
}

使用spring-3.2.1和quartz-2.1.6为我工作。

我只是将SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);作为Job.execute(JobExecutionContext context)方法的第一行。

答案 2 :(得分:13)

LINK已解决同样的问题:

我可以在Spring论坛上找到其他选项,你可以通过SchedulerFactoryBean传递对Spring应用程序上下文的引用。如下例所示:

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<propertyy name="triggers">
    <list>
        <ref bean="simpleTrigger"/>
            </list>
    </property>
    <property name="applicationContextSchedulerContextKey">
        <value>applicationContext</value>
</property>

然后在你的工作类中使用下面的代码,你可以获得applicationContext并获得你想要的任何bean。

appCtx = (ApplicationContext)context.getScheduler().getContext().get("applicationContextSchedulerContextKey");

你对Spring vs. Quartz实例化该类的假设是正确的。但是,Spring提供了一些类,可以让你在Quartz中进行一些原始的依赖注入。与SchedulerFactoryBean.setJobFactory()一起查看SpringBeanJobFactory。实质上,通过使用SpringBeanJobFactory,您可以在所有Job属性上启用依赖项注入,但仅适用于Quartz scheduler contextjob data map中的值。我不知道它支持的所有DI样式(构造函数,注释,setter ......)但我知道它支持setter注入。

谢谢,Rippon! 经过多次努力,我终于得到了这个工作,我的解决方案非常接近你的建议!关键是让我自己的Job扩展QuartzJobBean,并使用schedulerContextAsMap。

我确实在没有指定applicationContextSchedulerContextKey属性的情况下逃脱了 - 它没有为我工作。

为了他人的利益,以下是对我有用的最终配置:

    <bean id="quartzScheduler"  class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="configLocation" value="classpath:spring/quartz.properties"/>
        <property name="jobFactory">
            <bean  class="org.springframework.scheduling.quartz.SpringBeanJobFactory" />
        </property>
        <property name="schedulerContextAsMap">
            <map>
                <entry key="mailService" value-ref="mailService" />
            </map>
        </property>
</bean>
<bean id="jobTriggerFactory"
      class="org.springframework.beans.factory.config.ObjectFactoryCreatingFactoryBean">
    <property name="targetBeanName">
        <idref local="jobTrigger" />
    </property>
</bean>
<bean id="jobTrigger"   class="org.springframework.scheduling.quartz.SimpleTriggerBean"
    scope="prototype">
      <property name="group" value="myJobs" />
      <property name="description" value="myDescription" />
      <property name="repeatCount" value="0" />
</bean>

<bean id="jobDetailFactory"
      class="org.springframework.beans.factory.config.ObjectFactoryCreatingFactoryBean">
    <property name="targetBeanName">
        <idref local="jobDetail" />
    </property>
</bean>

<bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailBean"
scope="prototype">
<property name="jobClass" value="com.cambridgedata.notifications.EMailJob" />
<property name="volatility" value="false" />
<property name="durability" value="false" />
<property name="requestsRecovery" value="true" />
</bean> 
<bean id="notificationScheduler"   class="com.cambridgedata.notifications.NotificationScheduler">
    <constructor-arg ref="quartzScheduler" />
    <constructor-arg ref="jobDetailFactory" />
    <constructor-arg ref="jobTriggerFactory" />
</bean>

请注意,'mailService'bean是我自己的服务bean,由Spring管理。我可以在我的Job中访问它,如下所示:

    public void executeInternal(JobExecutionContext context)
    throws JobExecutionException {

    logger.info("EMailJob started ...");
    ....
    SchedulerContext schedulerContext = null;
    try {
        schedulerContext = context.getScheduler().getContext();
    } catch (SchedulerException e1) {
        e1.printStackTrace();
    }
    MailService mailService = (MailService)schedulerContext.get("mailService");
    ....

此配置还允许我动态调度作业,通过使用工厂获取触发器和JobDetails并以编程方式设置所需的参数:

    public NotificationScheduler(final Scheduler scheduler,
        final ObjectFactory<JobDetail> jobDetailFactory,
        final ObjectFactory<SimpleTrigger> jobTriggerFactory) {
    this.scheduler = scheduler;
    this.jobDetailFactory = jobDetailFactory;
    this.jobTriggerFactory = jobTriggerFactory;
           ...
        // create a trigger
        SimpleTrigger trigger = jobTriggerFactory.getObject();
        trigger.setRepeatInterval(0L);
    trigger.setStartTime(new Date());

    // create job details
    JobDetail emailJob = jobDetailFactory.getObject();

    emailJob.setName("new name");
    emailJob.setGroup("immediateEmailsGroup");
            ...

以下是@Component的代码:

安排工作的主要课程:

public class NotificationScheduler {

private SchedulerFactory sf;
private Scheduler scheduler;

@PostConstruct
public void initNotificationScheduler() {
    try {
    sf = new StdSchedulerFactory("spring/quartz.properties");
    scheduler = sf.getScheduler();
    scheduler.start();
            // test out sending a notification at startup, prepare some parameters...
    this.scheduleImmediateNotificationJob(messageParameters, recipients);
        try {
            // wait 20 seconds to show jobs
            logger.info("sleeping...");
            Thread.sleep(40L * 1000L); 
            logger.info("finished sleeping");
           // executing...
        } catch (Exception ignore) {
        }

      } catch (SchedulerException e) {
    e.printStackTrace();
    throw new RuntimeException("NotificationScheduler failed to retrieve a Scheduler instance: ", e);
    }
}


public void scheduleImmediateNotificationJob(){
  try {
    JobKey jobKey = new JobKey("key");
    Date fireTime = DateBuilder.futureDate(delayInSeconds, IntervalUnit.SECOND);
    JobDetail emailJob = JobBuilder.newJob(EMailJob.class)
    .withIdentity(jobKey.toString(), "immediateEmailsGroup")
        .build();

    TriggerKey triggerKey = new TriggerKey("triggerKey");
    SimpleTrigger trigger = (SimpleTrigger) TriggerBuilder.newTrigger() 
        .withIdentity(triggerKey.toString(), "immediateEmailsGroup")
        .startAt(fireTime)
        .build();

    // schedule the job to run
    Date scheduleTime1 = scheduler.scheduleJob(emailJob, trigger);
  } catch (SchedulerException e) {
    logger.error("error scheduling job: " + e.getMessage(), e);
    e.printStackTrace();
      }
}

@PreDestroy
public void cleanup(){
    sf = null;
    try {
        scheduler.shutdown();
    } catch (SchedulerException e) {
        e.printStackTrace();
    }
}

除了@Component注释之外,EmailJob与我的第一个帖子相同:

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

Spring的配置文件有:

...
<context:property-placeholder location="classpath:spring/*.properties" />
<context:spring-configured/>
<context:component-scan base-package="com.mybasepackage">
  <context:exclude-filter expression="org.springframework.stereotype.Controller"
        type="annotation" />
</context:component-scan>
<bean id="mailSenderImpl" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="host" value="${mail.host}"/>
    <property name="port" value="${mail.port}"/>
    ...
</bean>
<bean id="notificationScheduler" class="com.mybasepackage.notifications.NotificationScheduler">
</bean>

一个简单的解决方案是在作业数据映射中设置spring bean,然后在作业类中检索bean,例如

// the class sets the configures the MyJob class 
    SchedulerFactory sf = new StdSchedulerFactory();
    Scheduler sched = sf.getScheduler();
    Date startTime = DateBuilder.nextGivenSecondDate(null, 15);
    JobDetail job = newJob(MyJob.class).withIdentity("job1", "group1").build();
    job.getJobDataMap().put("processDataDAO", processDataDAO);

`

 // this is MyJob Class

Hary https://stackoverflow.com/a/37797575/4252764的解决方案非常有效。它更简单,不需要这么多特殊工厂bean,并支持多个触发器和作业。 只需补充一点,Quartz作业可以是通用的,特定的作业可以作为常规的Spring bean实现。

public interface BeanJob {
  void executeBeanJob();
}

public class GenericJob implements Job {

  @Override
  public void execute(JobExecutionContext context) throws JobExecutionException {
    JobDataMap dataMap = context.getMergedJobDataMap();
    ((BeanJob)dataMap.get("beanJob")).executeBeanJob();    
  }

}

@Component
public class RealJob implements BeanJob {
  private SomeService service;

  @Autowired
  public RealJob(SomeService service) {
    this.service = service;
  }

  @Override
  public void executeBeanJob() {
      //do do job with service
  }

}

一种简单的方法是使用@Component注释来注释Quartz Jobs,然后Spring会为你做所有的DI魔术,因为它现在被认为是一个Spring bean。我必须为AspectJ方面做类似的事情 - 在我使用Spring @Component刻板印象注释它之前,它不是一个Spring bean。

这是一个相当古老的帖子,仍然有用。提出这两个解决方案的所有解决方案都没有什么条件可以解决所有问题:

  • SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);这假定或要求它是一个基于网络的弹簧项目
  • 前面回答中提到的基于
  • AutowiringSpringBeanJobFactory的方法非常有帮助,但答案是针对那些不使用纯香草石英api而是使用Spring的石英包装的人来做的。相同。

如果你想继续使用纯Quartz实现进行调度(使用Spring的Quartz with Autowiring功能),我可以按如下方式进行:

我希望尽可能多地使用石英方式,因此小黑客证明是有帮助的。

 public final class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory{

    private AutowireCapableBeanFactory beanFactory;

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

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


@Configuration
public class SchedulerConfig {   
    @Autowired private ApplicationContext applicationContext;

    @Bean
    public AutowiringSpringBeanJobFactory getAutowiringSpringBeanJobFactory(){
        return new AutowiringSpringBeanJobFactory(applicationContext);
    }
}


private void initializeAndStartScheduler(final Properties quartzProperties)
            throws SchedulerException {
        //schedulerFactory.initialize(quartzProperties);
        Scheduler quartzScheduler = schedulerFactory.getScheduler();

        //Below one is the key here. Use the spring autowire capable job factory and inject here
        quartzScheduler.setJobFactory(autowiringSpringBeanJobFactory);
        quartzScheduler.start();
    }

quartzScheduler.setJobFactory(autowiringSpringBeanJobFactory);为我们提供了一个自动连接的作业实例。由于AutowiringSpringBeanJobFactory隐式实现了JobFactory,我们现在启用了一个可自动加线的解决方案。希望这有帮助!

只需从QuartzJobBean扩展您的工作

public class MyJob extends QuartzJobBean {

    @Autowired
    private SomeBean someBean;

    @Override
    protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println("Some bean is " + someBean.toString());
    }

}

Jdbc作业存储区

如果您正在使用jdbc作业存储库,那么Quartz将使用其他类加载器。这样可以避免所有自动装配的解决方法,因为弹簧对象来自石英方面,因为它们来自不同的类加载器。

要解决此问题,必须在石英属性文件中设置默认的类加载器,如下所示:

lazy var buttonsArray = {
    [buttonOne, buttonTwo, buttonThree]
}()

...

if buttonsArray[index]?.isOn == true {
        buttonsArray[index]?.buttonPressed()
}

作为参考: https://github.com/quartz-scheduler/quartz/issues/221

当我想调用事务方法时,上述所有解决方案都不适用于Spring 5,Hibernate 5和Quartz 2.2.3!

因此,我实现了此解决方案,该解决方案可自动启动调度程序并触发作业。我在dzone找到了很多这样的代码。因为我不需要动态创建触发器和作业,所以我希望通过Spring Configuration预定义静态触发器,而仅将作业公开为Spring组件。

我的基本配置如下

@Configuration
public class QuartzConfiguration {

  @Autowired
  ApplicationContext applicationContext;

  @Bean
  public SchedulerFactoryBean scheduler(@Autowired JobFactory jobFactory) throws IOException {
    SchedulerFactoryBean sfb = new SchedulerFactoryBean();

    sfb.setOverwriteExistingJobs(true);
    sfb.setAutoStartup(true);
    sfb.setJobFactory(jobFactory);

    Trigger[] triggers = new Trigger[] {
        cronTriggerTest().getObject()
    };
    sfb.setTriggers(triggers);
    return sfb;
  }

  @Bean
  public JobFactory cronJobFactory() {
    AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
    jobFactory.setApplicationContext(applicationContext);
    return jobFactory;
  }

  @Bean 
  public CronTriggerFactoryBean cronTriggerTest() {
    CronTriggerFactoryBean tfb = new CronTriggerFactoryBean();
    tfb.setCronExpression("0 * * ? * * *");

    JobDetail jobDetail = JobBuilder.newJob(CronTest.class)
                            .withIdentity("Testjob")
                            .build()
                            ;

    tfb.setJobDetail(jobDetail);
    return tfb;
  }

}

如您所见,您拥有调度程序和通过cron表达式定义的简单测试触发器。您显然可以选择任何您喜欢的调度表达式。然后,您需要像这样的AutowiringSpringBeanJobFactory

public final class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware {

  @Autowired
  private ApplicationContext applicationContext;

  private SchedulerContext schedulerContext;

  @Override
  public void setApplicationContext(final ApplicationContext context) {
    this.applicationContext = context;
  }


  @Override
  protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
    Job job = applicationContext.getBean(bundle.getJobDetail().getJobClass());
    BeanWrapper bw = PropertyAccessorFactory.forBeanPropertyAccess(job);

    MutablePropertyValues pvs = new MutablePropertyValues();
    pvs.addPropertyValues(bundle.getJobDetail().getJobDataMap());
    pvs.addPropertyValues(bundle.getTrigger().getJobDataMap());

    if (this.schedulerContext != null)
    {
        pvs.addPropertyValues(this.schedulerContext);
    }
    bw.setPropertyValues(pvs, true);

    return job;
  }  

  public void setSchedulerContext(SchedulerContext schedulerContext) {
    this.schedulerContext = schedulerContext;
    super.setSchedulerContext(schedulerContext);
  }

}

在这里,您将常规应用程序上下文和您的工作联系在一起。这是重要的差距,因为通常Quartz启动它的工作线程,这些工作线程与您的应用程序上下文无关。这就是为什么您无法执行事务处理方法的原因。最后缺少的是一份工作。看起来像那样

@Component
public class CronTest implements Job {

  @Autowired
  private MyService s;

  public CronTest() {
  }

  @Override
  public void execute(JobExecutionContext context) throws JobExecutionException {
    s.execute();
  }

}

这不是一个完美的解决方案,因为您仅是用于调用服务方法的额外类。但尽管如此,它仍然有效。

这是正确答案http://stackoverflow.com/questions/6990767/inject-bean-reference-into-a-quartz-job-in-spring/15211030#15211030。并将适用于大多数人。但是,如果您的web.xml不知道所有applicationContext.xml文件,那么quartz作业将无法调用这些bean。我不得不做一个额外的图层来注入额外的applicationContext文件

public class MYSpringBeanJobFactory extends SpringBeanJobFactory
        implements ApplicationContextAware {

    private transient AutowireCapableBeanFactory beanFactory;

    @Override
    public void setApplicationContext(final ApplicationContext context) {

        try {
                PathMatchingResourcePatternResolver pmrl = new PathMatchingResourcePatternResolver(context.getClassLoader());
                Resource[] resources = new Resource[0];
                GenericApplicationContext createdContext = null ;
                    resources = pmrl.getResources(
                            "classpath*:my-abc-integration-applicationContext.xml"
                    );

                    for (Resource r : resources) {
                        createdContext = new GenericApplicationContext(context);
                        XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(createdContext);
                        int i = reader.loadBeanDefinitions(r);
                    }

            createdContext.refresh();//important else you will get exceptions.
            beanFactory = createdContext.getAutowireCapableBeanFactory();

        } catch (IOException e) {
            e.printStackTrace();
        }



    }

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

您可以添加希望石英了解的任意数量的上下文文件。

上面的解决方案很棒,但在我的情况下注射不起作用。我需要使用autowireBeanProperties,可能是由于我的上下文配置方式:

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);
        beanFactory.autowireBeanProperties(job, AutowireCapableBeanFactory.AUTOWIRE_BY_TYPE, true);
        return job;
    }
}

我遇到了类似的问题,并通过以下方法从中得出:

<!-- Quartz Job -->
<bean name="JobA" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
    <!-- <constructor-arg ref="dao.DAOFramework" /> -->
     <property name="jobDataAsMap">
    <map>
        <entry key="daoBean" value-ref="dao.DAOFramework" />
    </map>
</property>
    <property name="jobClass" value="com.stratasync.jobs.JobA" />
    <property name="durability" value="true"/>
</bean>

在上面的代码中,我将dao.DAOFramework bean注入JobA bean,在ExecuteInternal方法内部,您可以获得注入的bean,如:

  daoFramework = (DAOFramework)context.getMergedJobDataMap().get("daoBean");

我希望它有所帮助!谢谢。

当您已在项目中使用真实的AspectJ时,您可以使用@Configurable注释作业bean类。然后Spring将注入此类,即使它是通过new

构造的

答案 19 :(得分:0)

确保你的

AutowiringSpringBeanJobFactory extends SpringBeanJobFactory 

依赖性来自

    "org.springframework:spring-context-support:4..."

而不是来自

    "org.springframework:spring-support:2..."

它要我使用

@Override
public Job newJob(TriggerFiredBundle bundle, Scheduler scheduler)

而不是

@Override
protected Object createJobInstance(final TriggerFiredBundle bundle)

因此无法自动装配工作实例。
