I was working with an application that needed to be run as a daemon. When the application is shutdown, we needed to do it in a clean manner, and release resources. So the question becomes how is it done.Fortunately, the
Runtime
class provides mechanism for adding a shutdown hook. The shutdown hook code below was added to the constructor. The shutdown
method is invoked when the application is shutdown, for example CTRL+C.// add shutdown hook to stop server Runtime.getRuntime().addShutdownHook(new Thread() { @Override public void run() { shutdown(); } }); } public void shutdown() { // add code to cleanly shutdown service here. }
