Graceful Shutdown

Graceful shutdown is supported with all four embedded web servers (Jetty, Reactor Netty, Tomcat, and Undertow) and with both reactive and servlet-based web applications. It occurs as part of closing the application context and is performed in the earliest phase of stopping SmartLifecycle beans. This stop processing uses a timeout which provides a grace period during which existing requests will be allowed to complete but no new requests will be permitted. The exact way in which new requests are not permitted varies depending on the web server that is being used. Jetty, Reactor Netty, and Tomcat will stop accepting requests at the network layer. Undertow will accept requests but respond immediately with a service unavailable (503) response.

Note
 Graceful shutdown with Tomcat requires Tomcat 9.0.33 or later.

To enable graceful shutdown, configure the configprop:server.shutdown[] property, as shown in the following example:

server:
  shutdown: "graceful"

To configure the timeout period, configure the configprop:spring.lifecycle.timeout-per-shutdown-phase[] property, as shown in the following example:

spring:
  lifecycle:
    timeout-per-shutdown-phase: "20s"
Important
 Using graceful shutdown with your IDE may not work properly if it does not send a proper SIGTERM signal. See the documentation of your IDE for more details.
