Spring Boot 2.4.3 - Actuator /startup endpoint not found

I have a spring boot app that I upgraded from v2.2.x to now be v2.4.3.

I saw in their documentation that there is a new actuator endpoint of /startup, however it does not exist when I start my app. enter image description here

There is no special requirement according to their documentation here

I am using spring-boot-admin-starter-client v2.4.3 which provides spring-boot-actuator v2.4.3, and i even have management.endpoint.startup.enabled=true in my application.properties file.

Has anyone else used this version of spring boot and gotten this actuator enpoint to work?

May be you are using BootstrapApplicationListener which build the application context again but ignores the previous applicationStartup, so it sets the default, this is a bug in spring-cloud-context:3.0.0

You need to tweak startup configuration:

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(DemoApplication.class);
        app.setApplicationStartup(new BufferingApplicationStartup(1000));
        app.run(args);
    }
}

In application.properties:

management.endpoints.web.exposure.include=startup

If you want to visualize startup events check out this tool I made some months ago https://spring-boot-startup-analyzer.netlify.app/ (look at the configuration instructions as you need to enable CORS on this endpoint)
