问题
My application consists of 2 servlets,the major one loads the config files in init method and processes get/post requests, if anything fails during config load, i need to stop the application.
as far i know, i couldnt be able to stop whole application context through some java code ,hence i'm throwing UnavailableException in Servlet.hence i wont be processing get/post request.
but the second servlet does some dynamic reload of configuration on demand.but irrespective of major servlet failed or succeed,it processes reloading requests.
can you suggest a way to check the status of major servlet (running,stopped).so that second servlet can take decision whether to accept reload request or not.
回答1:
Just share some status variable, like AtomicBoolean between two servlets. By the way, it's more clear design to make both servlets just accept http requests, decode them and pass requests to corresponding business-logic objects. This way, servlets will contain only logic concerned with HTTP sending/receiving.
