Graceful shutdown

Graceful shutdown is currently supported by four built-in embedded Web servers (Jetty, Reactor Netty, Tomcat, and Undertow) as well as responsive and servlet-based Web applications.

When the shutdown buffer time is configured, the Web server will no longer allow new requests upon shutdown and will wait for the buffer time for active requests to complete.

Service availability probe

Spring Boot 2.3.0 has built-in application availability judgment to track whether an application is handling active status and ready to handle requests.
