在我启动tomcat后的一段时间后，Jobs会激活两次，如果我从工作目录和爆炸的war文件中删除所有缓存并重新部署它只会激活一次该作业。有任何想法吗？也许缓存豆？

@jhouse重新部署似乎是我在重新部署之后粘贴了线程转储的问题，我的选择是什么？

如果我停止服务器，然后检查线程转储它是空的，然后启动（不清理）服务器，该线程泵有重复的线程运行

好奇，你的web.xml中是否配置了spring-report.xml？喜欢这个？

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:spring-report.xml
    </param-value>
</context-param>

我问的原因是因为你发表了上述声明： -

private static BeanFactory factory = new ClassPathXmlApplicationContext("spring-report.xml");

如果你在web.xml和Java代码中都有spring-report.xml，那么是的，它可能会激活两次作业。

Quartz触发两次bean缓存问题？
