Я настроил некоторые планировщики весной. Когда я пытаюсь запустить свое веб-приложение, оно выдает следующую ошибку и останавливается. Мое приложение фактически не запускается. Мой планировщик выглядит примерно так также, когда я выключаю tomcat, некоторые кварцевые нити незавершение работы

Я реализовал слушатель:
import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import org.quartz.SchedulerException;
import org.quartz.impl.StdSchedulerFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class QuartzServletContextListener implements ServletContextListener {
final Logger log = LoggerFactory.getLogger(QuartzServletContextListener.class);
public static final String QUARTZ_FACTORY_KEY =
"org.quartz.impl.StdSchedulerFactory.KEY";
private ServletContext ctx = null;
private StdSchedulerFactory factory = null;
public void contextInitialized(ServletContextEvent sce) {
ctx = sce.getServletContext();
try {
factory = new StdSchedulerFactory();
// Start the scheduler now
factory.getScheduler().start();
log.info("Storing QuartzScheduler Factory at"
+ QUARTZ_FACTORY_KEY);
ctx.setAttribute(QUARTZ_FACTORY_KEY, factory);
} catch (Exception ex) {
log.error("Quartz failed to initialize", ex);
}
}
public void contextDestroyed(ServletContextEvent sce) {
try {
log.info("shutting down");
factory.getScheduler().shutdown();
Thread.sleep(1000);
} catch (InterruptedException ex) {
log.error("Quartz failed to shutdown", ex);
} catch (SchedulerException ex) {
log.error("Quartz failed to shutdown", ex);
}
}
}
И добавил в web.xml
<listener>
<listener-class>xx.yy.QuartzServletContextListener</listener-class>
</listener>
Когда я пытаюсь использовать shutdown.sh, я все еще могу активировать некоторые потоки и активировать Java-процесс tomcat.
Также следует упомянуть, что у меня есть 3-4 планировщика для различных заданий, как упомянуто выше в контексте приложения.
