我想在Rails关闭时运行一些清理代码-可能吗?我的情况是，我在后台有一些线程(我正在使用jruby并调用java)在整个进程的生命周期中都存在，我需要让他们知道关闭自己的线程

I'd like to have some cleanup code run when Rails is shutting down - is that possible? My situation is that I have a few threads in the background (I'm using jruby and calling into java) that live for the life of the process and I need to let them know to shut themselves down

谢谢！

推荐答案
