java Quartz 内存泄漏-PHP中文网问答

我用定时器启动应用的时候发现内存泄漏，具体报错如下：

十月 30, 2015 2:30:12 下午 org.apache.catalina.startup.HostConfig undeploy
信息: Undeploying context [/ChinaMoney Maven Webapp]
十月 30, 2015 2:30:15 下午 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc
严重: The web application [/ChinaMoney Maven Webapp] registered the JDBC driver [net.sourceforge.jtds.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.
十月 30, 2015 2:30:15 下午 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
严重: The web application [/ChinaMoney Maven Webapp] appears to have started a thread named [startQuertz_Worker-1] but has failed to stop it. This is very likely to create a memory leak.

定时器定义如下：


        
            
                
            
            
                30 38 09 * * ?
            
        
        
        
            
                
                    
                
            
               
                  
                    buy_it_now
                    2  
                    org.quartz.plugins.management.ShutdownHookPlugin
                    true
                    true

请各位大神看看问题出在哪里了~跪谢！！！

public void contextDestroyed(ServletContextEvent sce) { // 卸载JDBC驱动 Enumeration<Driver> drivers = DriverManager.getDrivers(); while(drivers.hasMoreElements()){ try { Driver driver = drivers.nextElement(); DriverManager.deregisterDriver(driver); } catch (SQLException e) { e.printStackTrace(); } } // 然后我相信你还需要停止Quartz的线程，你自己看下文档怎么停止。 }
