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
factorybean" destroy-method="destroy">
crontrigger"/>
factorybean">
etobject" ref="Adaptor"/>
getmethod" value="xxxxxx"/>
crontrigger" class="org.springframework.scheduling.quartz.crontriggerBean">

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：
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
servletcontextlistener 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.
