Quartz和Spring：动态调度

Question

我有一个web服务，它对某个作业进行动态调度。job是一个Java类，它扩展了Quartz job接口

public class StartJob implements Job {
    private String jobId;
    private DAO dao;

    public void execute(JobExecutionContext context) throws JobExecutionException {

        JobDataMap dataMap = context.getMergedJobDataMap();

        //some logic here
    }

    // getters and setters
}

我还公开了一个API，它接收一个jobId、cron表达式，并调度一个新的StartJob（它将具有接收到的ID）。下面是我的Spring配置：

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = { "persistence.dao" })
@ImportResource({"spring-quartz-context.xml"})
public class BeanConfig {
    //wired from the xml
    @Autowired JobDetailFactoryBean jobDetailFactory;
    @Autowired CronTriggerFactoryBean cronTriggerFactory;

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean() {
        SchedulerFactoryBean bean = new SchedulerFactoryBean();
        bean.setApplicationContextSchedulerContextKey("applicationContext");
        bean.setSchedulerName("MyScheduler");
        Map<String, Object> schedulerContextAsMap = new HashMap<String, Object>();
        bean.setSchedulerContextAsMap(schedulerContextAsMap);
        // quartzproperties not reported
        bean.setQuartzProperties(quartzProperties());

        return bean;
    }

    //other bean definitions

}

<bean name="complexJobDetail"
    class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
    <property name="jobClass" value="jobs.StartJob" />
    <property name="durability" value="true" />
</bean>

<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
    <property name="jobDetail" ref="complexJobDetail" />
    <property name="cronExpression" value="0/5 * * ? * SAT-SUN" />
</bean>

JobDetail job = jobDetailFactory.getObject();
job.setName(aGeneratedUUID);
CronTrigger trigger = cronTriggerFactory.getObject();
trigger.setCronExpression(aDynamicCronExpression);

scheduler.schedule(job, trigger);

我错过了什么？这样的配置正确吗？从工厂中检索到的作业和触发器是同一个类的新实例还是同一个类实例？

Answer 1

问题是我没有调用afterPropertiesSet()方法。所以

jobDetailFactory.setName(generatedUUID);
jobDetailFactory.afterPropertiesSet();
JobDetail job = jobDetailFactory.getObject();

工作，则创建的作业具有新名称。
