StartApplication is not working

See original GitHub issue

Hello, I have been assigned to create a method that will start an application. I have the code implemented correctly yet nothing is happening when I run my project. I’m an intern, so i am new to this and therefore I am not so familiar with cloudfoundry overall. If you can help me in any way that would be much appreciated.

My code is written below:

public Mono<Map<String, Object>> startApplication(String orgName, String spaceName, String appName){ 
        return this.getApplications(orgName, spaceName)
                .flatMap(ApplicationDetail ->,Mono.just(ApplicationDetail.getRequestedState().equals("STOPPED") ?
                                runApplication(orgName, spaceName, appName): "the application is already running")))
                .filter(hmap -> hmap.getT1().equalsIgnoreCase(appName))
    public Mono<Void> runApplication(String appName, String orgName, String spaceName) {
        final CloudFoundryOperations cloudFoundryOperations = this.getCloudFoundryOperations(orgName, spaceName);
           return cloudFoundryOperations.applications()

Thank you for all your help! The method now works properly 👍

Reactor can do conditionals such as if in a variety of ways, but often the best approach is a filter. Excuse the formatting as I’m coding in a browser, but I think in your case that would look like this:

this.getApplications(orgName, spaceName)
            .filter(applicationDetail -> applicationDetail.getName().equals(appName))
            .filter(applicationDetail -> applicationDetail.getRequestedState().equals("STOPPED"))
            .flatMap(applicationDetail -> runApplication(orgName, spaceName, appName))

Incidentally, the start() method here already handles this scenario (and handles waiting for the application to start), so be sure you’re not reinventing the wheel.
