我在spring中配置了一些调度程序.当我尝试启动我的Web应用程序时,它会抛出以下错误并停止.我的应用程序实际上并没有启动.我的调度程序看起来也是这样的,当我关闭tomcat时,一些石英线程没有关闭

@H_403_6@factorybean" destroy-method="destroy">
    factorybean">
        

堆栈跟踪：

@H_403_6@INFO: Closing Spring root WebApplicationContext

SEVERE: The web application [/] registered the JBDC driver [com.MysqL.jdbc.Driver] but Failed to unregister it when the web application was stopped. To prevent a memory leak,the JDBC Driver has been forcibly unregistered.

SEVERE: The web application [/] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@71ee88dd]) and a value of type [org.apache.cxf.bus.CXFBusImpl] (value [org.apache.cxf.bus.CXFBusImpl@409468ca]) but Failed to remove it when the web application was stopped. This is very likely to create a memory leak.

我实现了监听器：

@H_403_6@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);
         }
     }
 }

并在web.xml中添加

@H_403_6@

当我尝试使用shutdown.sh时,我仍然可以使一些线程处于活动状态并且tomcat java进程处于活动状态.

另外要提到的是,我在应用程序上下文中提到了针对不同作业的一些3到4个调度程序.
