Question

我试着在春天使用石英调度程序。配置多个作业时，我得到以下异常

Job2中方法jobTrigger的参数0需要一个无法找到的类型为'org.quartz.JobDetail'的bean。

quartz - v2.3，Spring - v4.2.x

配置类

127.0.0.1    testapp.yourdomain.com

SpringBeanJobFactory

proxy revers

}

@Configuration
 public class SchedulerConfig {

private static final Logger LOG = LoggerFactory.getLogger(SchedulerConfig.class);

@Autowired
List<Trigger> triggers;

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

@Bean
public SchedulerFactoryBean schedulerFactoryBean(JobFactory jobFactory)  throws IOException {
    SchedulerFactoryBean factory = new SchedulerFactoryBean();
          factory.setAutoStartup(true);
    factory.setJobFactory(jobFactory);
         factory.setQuartzProperties(quartzProperties());
    if (triggers != null && !triggers.isEmpty()) {
         LOG.info("starting jobs... Total Triggers - " + triggers.size());
        factory.setTriggers(triggers.toArray(new Trigger[triggers.size()]));
    }

    return factory;
}

@Bean
public Properties quartzProperties() throws IOException {
    PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
    propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
    propertiesFactoryBean.afterPropertiesSet();
    return propertiesFactoryBean.getObject();
}


public static CronTriggerFactoryBean createCronTrigger(JobDetail jobDetail, String cronExpression) {
    CronTriggerFactoryBean factoryBean = new CronTriggerFactoryBean();
    factoryBean.setJobDetail(jobDetail);
    factoryBean.setCronExpression(cronExpression);
    factoryBean.setMisfireInstruction(SimpleTrigger.MISFIRE_INSTRUCTION_FIRE_NOW);
    return factoryBean;
}

public static JobDetailFactoryBean createJobDetail(Class jobClass) {
    JobDetailFactoryBean factoryBean = new JobDetailFactoryBean();
    factoryBean.setJobClass(jobClass);
    factoryBean.setDurability(true);
    return factoryBean;
}

工作2

public final class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware {

private static final Logger LOG = LoggerFactory.getLogger(AutowiringSpringBeanJobFactory.class);

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);
    LOG.info("create job instance");
    beanFactory.autowireBean(job);
    return job;
}

Service类有Spring JPA repos。问题的根本原因是以下自动服务。如果我从两个作业中删除以下自动装配的服务，它可以正常工作。

@Autowired 私人服务;

如果这个自动装配的bean只有一个作业，那么没有例外。如何使用相同的自动连接依赖项配置多个作业？造成这个问题的原因是什么？

Answer 1

这是您在一个配置文件中处理多个Quartz作业时引用的http://www.baeldung.com/spring-quartz-schedule的修改版本。为简洁起见，我不包括整个QrtzSheduler类只是替换调度器方法和在触发器中使用@Qualifier引用：

...
@Bean
public Scheduler scheduler(Map<String, JobDetail> jobMap, Set<? extends Trigger> triggers) throws SchedulerException, IOException {

    StdSchedulerFactory factory = new StdSchedulerFactory();
    factory.initialize(new ClassPathResource("quartz.properties").getInputStream());

    logger.debug("Getting a handle to the Scheduler");
    Scheduler scheduler = factory.getScheduler();
    scheduler.setJobFactory(springBeanJobFactory());
    Map<JobDetail,Set<? extends Trigger>> triggersAndJobs = new HashMap<JobDetail,Set<? extends Trigger>>;
    for(JobDetail jobDetail : jobMap.getValues()){
        for(Trigger trigger : triggers){
            if(trigger.getJobKey().equals(jobDetail.getKey())){
               Set<Trigger> set = new HashSet<>();
               set.add(trigger);
               triggerAndJobs.put(jobDetail,set);
            }
        }
    }
    scheduler.scheduleJobs(triggersAndJobs, false);

    logger.debug("Starting Scheduler threads");
    scheduler.start();
    return scheduler;
}

@Bean(name="jobOne")
public JobDetail jobDetailOne() {

    ...
}

@Bean(name="jobTwo")
public JobDetail jobDetailTwo() {

   ...
}

@Bean
public Trigger triggerOne(@Qualifier("jobOne")JobDetail jobDetail) {

   ...
}

@Bean
public Trigger triggerTwo(@Qualifier("jobTwo")JobDetail jobDetail) {

   ...
}

Answer 2

jobTrigger方法期望参数JobDetail，但传递的bean类型为JobDetailFactoryBean。

也许你应该做出以下改变或类似的事情。

@Bean(name = "jobBean1")
public JobDetail job() {
    return SchedulerConfig.createJobDetail(this.getClass()).getObject();
}

对于job2也一样。

顺便说一下，你提到Spring - v1.5。您实际使用的是哪个版本的Spring？

Answer 3

您正尝试在Spring 4.2中使用Spring启动配置。

尝试在Job类中更改以下方法，如下所示

var set of 1..100: y:: output_var;

也需要使用弹簧4.3，因为你需要

@Bean(name = "jobBean1")
public JobDetail job() {
    return SchedulerConfig.createJobDetail(this.getClass()).getObject();
}

@Bean(name = "jobBean1Trigger")
public CronTrigger jobTrigger(@Qualifier("jobBean1")JobDetail jobDetail) {
    return SchedulerConfig.createCronTrigger(jobDetail, frequency).getObject();
}

我相信Collection Autowire仅适用于4.3

Answer 4

我遇到了同样的问题，经过一番挣扎后我才能解决它。它可能适用于作业类中使用的注释。我看到你正在使用@Component，就像我的情况一样。而石英调度程序配置则使用@Configuration标记进行注释。

解决方案是使用@Configuration标记为您的作业添加注释。我的猜测是@Bean注释类中构造的@Component在初始化@Configuration注释的阶段中不是完整的构造/映射。

我遇到了同样的问题，但现在已经解决

package com.crif.credity.config;

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 class SchedulerJobFactory extends SpringBeanJobFactory implements ApplicationContextAware {
    private AutowireCapableBeanFactory beanFacotry;

    @Override
    protected Object createJobInstance(TriggerFiredBundle triggerBundle) throws Exception {
        Object createJobInstance = super.createJobInstance(triggerBundle);
        beanFacotry.autowireBean(createJobInstance);
        return createJobInstance;
    }

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) {
        beanFacotry = applicationContext.getAutowireCapableBeanFactory();
    }

}

在配置Java文件中，您可以在bean下面创建

@Autowired
    private ApplicationContext applicationContext;

/** The data source. */
    @Bean
    public SchedulerFactoryBean schedulerFactoryBean() throws IOException {
        SchedulerJobFactory jobFactory = new SchedulerJobFactory();
        jobFactory.setApplicationContext(applicationContext);


        SchedulerFactoryBean factoryBean = new SchedulerFactoryBean();
        factoryBean.setOverwriteExistingJobs(true);     
        factoryBean.setJobFactory(jobFactory);
        return factoryBean;
    }

此后执行job class。您可以使用自动接线

package com.crif.credity.jobs;




public class Test implements Job  {

    @Autowired 
    private BatchClientService batchClientService;



    @Override
public void execute(JobExecutionContext context) throws JobExecutionException{
        try {
            batchClientService.executeJob(CredityJob.NEWSCHECK, instanceId);
        } catch (Exception ex) {
            LOG.info(ex.getMessage());
        }
    }

}

使用Spring Boot在Quartz多个作业中自动装配不起作用
