java - Guice + Quartz + iBatis

Question

我正在尝试将 Guice (Java)、Quartz 调度程序和 iBatis ( iBaGuice ) 连接在一起以执行以下操作:

1. 使用 main() 启动命令行实用程序扫描仪
2. 定期扫描目录(作为参数提供)以查找包含格式化输出(XML 或 YAML)的文件
3. 当检测到文件时，解析并输出结果到数据库

问题:

1. 我用过this example连接 Guice 和 Quartz。然而，我遗漏了一些我在评论中询问的重要细节，但这篇文章有些过时了，所以我也在这里引用它:

1. It's not obvious how to set-up the scheduler. Where and how would I wire the Trigger (I can use Trigger#makeMinutelyTrigger)?
2. I really have just one type of job I will be executing, I understand that details in the JobFactory#newJob are coming from the TriggerFiredBundle parameter but where/how do I wire that? And where/how do I create or wire concrete Job?

附注通过创建和连接 ScheduleProvider，我得到了进一步的了解。现在我对如何在下面的代码片段中实际安排作业感到困惑。看来我的 JobFactory#newJob 方法从未被调用

public class CollectorServiceImpl implements CollectorService {
Scheduler scheduler;

/**
 * @throws SchedulerException
 */
@Inject
public CollectorServiceImpl(final SchedulerFactory factory, final GuiceJobFactory jobFactory)
        throws SchedulerException {
    scheduler = factory.getScheduler();
    scheduler.setJobFactory(jobFactory);
}

/**
 * @throws SchedulerException
 * @see teradata.quantum.reporting.collector.service.CollectorService#start()
 */
@Override
public void start() throws SchedulerException {
    Trigger trigger = TriggerUtils.makeMinutelyTrigger("MIN_TRIGGER");
    scheduler.scheduleJob(trigger); // this fails trigger validation since no job name is provided
    scheduler.start();
}

}

Answer 1

您问题的核心是，您实际上并没有安排工作类(class):

getScheduler().scheduleJob(new JobDetail("myFooJob", null, FooJob.class),
        TriggerUtils.makeMinutelyTrigger("MIN_TRIGGER"));
