使用Spring Boot在Quartz多个作业中自动装配不起作用

Question

我试着在春天使用石英调度器.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

@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;
}

SpringBeanJobFactory

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;
}

}

工作1

@Component
@DisallowConcurrentExecution
public class Job1 implements Job {

private final Logger log = LoggerFactory.getLogger(this.getClass());

@Value("${schedule}")
private String frequency;

@Autowired
private Service service;

@Override
public void execute(JobExecutionContext jobExecutionContext) {
    log.info("execute");
}

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

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

工作2

@Component
@DisallowConcurrentExecution
public class Job2 implements Job {

private final Logger log = LoggerFactory.getLogger(this.getClass());

@Value("${schedule}")
private String frequency;

@Autowired
private Service service;

@Override
public void execute(JobExecutionContext jobExecutionContext) {
    log.info("execute");
}

@Bean(name = "jobBean2")
public JobDetailFactoryBean job() {
    return SchedulerConfig.createJobDetail(this.getClass());
}

@Bean(name = "jobBean2Trigger")
public CronTriggerFactoryBean jobTrigger(@Qualifier("jobBean2")JobDetail jobDetail) {
    return SchedulerConfig.createCronTrigger(jobDetail, frequency);
}

Service类有Spring JPA repos.问题的根本原因是以下自动服务.如果我从这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？是什么导致这个问题？

这是您引用的用于在一个配置文件中处理多个 Quartz 作业的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，只是替换调度程序方法以及在触发器中使用 @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) {

   ...
}

您正在尝试将 Spring Boot 配置与 Spring 4.2 一起使用。

尝试更改 Job 类中的以下方法，如下所示

@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();
}

还可以使用 spring 4.3，因为您需要

@Autowired
List<Trigger> triggers;

我相信 Collection Autowire 仅适用于 4.3
