我正在创建一个cron调度程序,我正在使用以下代码: -
import org.quartz.CronScheduleBuilder;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.impl.StdSchedulerFactory;
import org.quartz.ScheduleBuilder;
public class CronSched {
public static void main(String[] args) throws SchedulerException {
System.out.println("Started");
JobDetail job = JobBuilder.newJob(CronJob.class).build();
Trigger t1 = TriggerBuilder.newTrigger().withIdentity("MAILER").withSchedule(CronScheduleBuilder.cronSchedule("0 33 2 1/1 * ? *")).build();
Scheduler sc = StdSchedulerFactory.getDefaultScheduler();
sc.start();
sc.scheduleJob(job,t1);
}
}
我正在使用以下语句编写终端代码: -
javac -cp ".:/home/aditya/CronSched/lib/quartz-2.2.3.jar: /home/aditya/CronSched/lib/slf4j-api-1.7.25.jar: /home/aditya/CronSched/lib/slf4j-simple-1.7.25.jar: " CronSched.java
并且在运行代码时我使用以下语句: -
java CronSched
我收到以下错误: -

您必须将所有必需品jar添加到运行时类路径中。
java -cp "quartz-2.2.3.jar:...." CronSched
