java 动态调度,Quartz和Spring：动态调度

我有一个Web服务，它可以完成某项工作 . 该作业是一个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一个cron表达式，并安排一个具有收到id的新StartJob . 这是我的 Spring configuration ：

@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 schedulerContextAsMap = new HashMap();

bean.setSchedulerContextAsMap(schedulerContextAsMap);

// quartzproperties not reported

bean.setQuartzProperties(quartzProperties());

return bean;

}

//other bean definitions

}

和spring-quartz-config.xml

class="org.springframework.scheduling.quartz.JobDetailFactoryBean">

What I want to do 类似于(伪代码)

JobDetail job = jobDetailFactory.getObject();

job.setName(aGeneratedUUID);

CronTrigger trigger = cronTriggerFactory.getObject();

trigger.setCronExpression(aDynamicCronExpression);

scheduler.schedule(job, trigger);

但问题是我无法更改作业名称，因此， only the first job is scheduled . 第一个作业使用JobDetailFactoryBean的名称(complexJobDetail)作为名称 .

我在这里失踪了什么？这个配置是否正确？从工厂检索的作业和触发器是同一个类的新实例，还是同一个类实例？
