我使用以下库.
> quartz-2.2.1
> spring-webmvc-3.2.9.RELEASE
在Apache Tomcat / 7.0.52(Ubuntu)上.
我使用Spring来配置Quartz.
@Configuration
class QuartzConfig {
@Bean
factorybeanfactorybean factory = new SchedulerfactorybeanWithShutdownDelay();

SEVERE: The web application [/feeder##1.5.0] appears to have started a thread named [scheduler_Worker-1] but has failed to stop it. This is very likely to create a memory leak.

丑陋的黑客是编写SchedulerFactoryBeanWithShutdownDelay类.
public class SchedulerFactoryBeanWithShutdownDelay extends SchedulerFactoryBean {
private static final int SHUTDOWN_TIMEOUT = 2000;
@Override
public void destroy() throws SchedulerException {
log.debug("Start shutdown of Quartz scheduler factory bean");
super.destroy();
try {
log.debug("wait {}ms to shutdown Quartz",SHUTDOWN_TIMEOUT);
Thread.sleep(SHUTDOWN_TIMEOUT);
log.debug("Quartz scheduler shutdown completed");
} catch (InterruptedException e) {
log.error("",e);
}
}
}
但是这个问题应该已经关闭：https://jira.terracotta.org/jira/browse/QTZ-192
我犯了错误还是可以确认？
最佳答案
Tomcat内存泄漏excellent article.阅读文章,启动您的Web应用程序,让Quartz作业执行,然后停止Web应用程序,然后进行Tomcat JVM的堆转储,将堆转储加载到Eclipse MAT中,找出哪些类导致内存泄漏.那么你应该能够解决这个问题.
