tomcat无法shutdown

tomcat无法shutdown，shutdown之后还有一些进程没有释放导致jvm还在活动（大概是这样）。

 

解决：程序中的线程设置为守护线程：setDaemon（true）

在servlet 中 destroy方法里面自己销毁线程

 

如果是spring则在bean后面配置 destroy-method="destroy" 

 

 

 

目前知道 

org.springframework.scheduling.quartz.SchedulerFactoryBean destroy无效（BUG？）

 

com.mysql.jdbc.Driver 不知道在哪销毁

pool-4-thread-1？这个是什么线程 不知道在哪

 

 

SchedulerFactoryBean destroy无效的问题 可以通过重写 destroy方法，在shutdown之后给一个 Thread.sleep(1000) 然后就可以了。

 

至于com.mysql.jdbc.Driver 为什么destroy不了就不太了解了。每次shutdown关闭不了之后只能去kill进程 很烦，

而且有时候端口还一直被占用状态中。

楼主，我这个quartz的销毁方法也没法成功。。Thread.sleep(1000) 还是不行啊。。。
com.mysql.jdbc.Driver没法释放。。。

严重: The web application [/lumi-ticket] registered the JDBC 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.
