Quartz调度器不运行cron作业

Question

我是想用 CronTrigger 在石英调度器中，调度器正在启动，但作业没有被触发。调度器正在启动，但作业没有被触发。以下是我的代码。

SchedulerFactory factory = new StdSchedulerFactory();
Scheduler scheduler = factory.getScheduler();
DateBuilder.evenMinuteDate(new Date());
JobDetail job = JobBuilder.newJob(Sample.class).withIdentity("job1", "group1").build();

CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "group1")
        .withSchedule(CronScheduleBuilder.cronSchedule("0 * * ? * *")).build();

scheduler.scheduleJob(job, trigger);

scheduler.start();

Sample 类代码中只有一条print语句。

当前输出如下。

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

当前版本：

<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>2.3.2</version>
</dependency>

我错过了什么吗？

这是你的例子，已经实现了Sample类。

public class TestCronJob {
    public static void main(String[] args) throws SchedulerException {
        SchedulerFactory factory = new StdSchedulerFactory();
        Scheduler scheduler = factory.getScheduler();
        DateBuilder.evenMinuteDate(new Date());
        JobDetail job = JobBuilder.newJob(Sample.class).withIdentity("job1", "group1").build();

        CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "group1")
                .withSchedule(CronScheduleBuilder.cronSchedule("0 * * ? * *")).build();

        scheduler.scheduleJob(job, trigger);

        scheduler.start();
    }

    public static class Sample implements Job {

        @Override
        public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
            System.out.println("From job: " + new Date());
        }
    }
}

它每分钟打印一次

From job: Tue May 26 17:59:00 EEST 2020
From job: Tue May 26 18:00:00 EEST 2020
...

所以，它是按照预期工作的 在你的情况下，可能是和日志框架有关，我看到你的输出中有这样的信息。
