I have a java class annotated with the jakarta.ws.rs-api annotations, which is a rest resource class. I have created an executor service as part of the resource class (which contains methods with annotations like @GET, @PUT, etc.), and am looking for a way to close this executor service upon the shutdown of the servlet container (jetty using jersey).
I came across @PreDestroy annotation, used it in the resource class, but it isn't getting invoked upon graceful shutdown of the container.
Is there a way where the resources like executor-service in a resource class can be closed with a predefined hook or annotation? Thanks!
One way of listening to the container's "shutdown" could be using an implementation of ServletContextListener interface, and writing the logic for closing your executor service under the contextDestroyed(ServletContext) method.
