Close SMTPAppender's thread pool when Tomcat shuts down

Question

I'm using Logback's SMTPAppender to send e-mails when certain logging events occur on my Tomcat.

The SMTPAppender can send e-mails asynchronously. Then however shutting down Tomcat fails because Tomcat can't close SMTPAppender's thread pool.

Is it somehow possible to close this thread pool when Tomcat is shutting down?

Answer 1

I found out: Stopping logback-classic

Answer 2

if you're using Tomcat, it seems that configuring Logback's Tomcat valve should resolve this issue for you:

Configuring the Valve will result in Tomcat automatically shutting down the associated ExecutorService upon shutdown.
