I have a ring project with the following configuration
:ring {:port 3000
:handler myservice.core/standalone-app
:init myservice.core/init!
:destroy myservice.core/destroy!}
These functions are simple, they just log. They may do more someday.
(defn init! [] (log/info "init!"))
(defn destroy! [] (log/info "destroy!"))
I build this kid with the uberwar thing. lein ring uberwar myservice.war
The jetty log shows the init! logging on startup, but the destroy! logging is nowhere to be seen. Is destroy even being called? How can I tell?
The full project is at https://github.com/robertkuhar/myservice
It turns out I needed to configure the logging framework. It seems strange in the absence of logging configuration allows init! to log to stdout, but destroy! goes nowhere.
I added logback to my project.clj as a dependency and gin'ed up a skeleton logback.xml config file and, viola!
