Spring Quartz =内存泄漏

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();
        final Map


今天搜索了很多为什么调度程序任务没有正确关闭…

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.
