Graceful Shutdown in Spring Boot

Grace Period for shutdown can be configured with server.shutdown.grace-period property.

• /hello returns HelloWorld and triggers a task internally which needs to be taken care before shutting down.
  • curl http://localhost:8080/hello -X GET - Command used to trigger the endpoint
• By default @PreDestroy can be used to hook a custom implementation after tomcat says all requests are processed and timeout has expired.
