I decided to use the simplest way and just restart the application if certificate is changed using spring actuator.

To do it we should enable restart endpoint int application.properties:

management.endpoint.restart.access=read_only

and in my ContainerConfiguration.java:

• autowire RestartEndpoint

• my method reloadSSLConfig now looking so:

private void reloadSSLConfig() { 
    restartEndpoint.restart(); 
}

PS: also I've found the article about hot reloading SSL in spring: SSL hot reload in Spring Boot 3.2.0
