Actuator BeansEndpoint does not list beans from parent

[shalom938]

We have a spring boot application with context hierarchy and where we add only the auto configuration classes we need.
the beans endpoint does not list beans from parent, i had to override the beans endpoint with a custor one that looks like that:

@ConfigurationProperties(prefix = "endpoints.beans", ignoreUnknownFields = false)
public class TaboolaBeansEndpoint extends BeansEndpoint {

    private final BELiveBeansView liveBeansView = new BELiveBeansView();

    private final JsonParser parser = JsonParserFactory.getJsonParser();


    @Override
    public void setApplicationContext(ApplicationContext context) throws BeansException {
        if (context.getEnvironment()
                .getProperty(LiveBeansView.MBEAN_DOMAIN_PROPERTY_NAME) == null) {
            this.liveBeansView.setApplicationContext(context);
        }
    }

    @Override
    public List<Object> invoke() {
        return this.parser.parseList(this.liveBeansView.getSnapshotAsJson());
    }




    public static final class BELiveBeansView extends LiveBeansView{

        Set<ConfigurableApplicationContext> contexts = new HashSet<ConfigurableApplicationContext>();

        @Override
        public void setApplicationContext(ApplicationContext applicationContext) {
            Assert.isTrue(applicationContext instanceof ConfigurableApplicationContext,
                    "ApplicationContext does not implement ConfigurableApplicationContext");

            if (applicationContext != null) {
                ApplicationContext current = applicationContext;
                while(current != null){
                    Assert.isTrue(applicationContext instanceof ConfigurableApplicationContext,
                            "ApplicationContext does not implement ConfigurableApplicationContext");
                    contexts.add((ConfigurableApplicationContext) current);
                    current = current.getParent();
                }
            }
        }


        @Override
        public String getSnapshotAsJson() {
            return generateJson(contexts);
        }
    }

}

We think changing BeansEndpoint.setApplicationContext to pick the root context may also fix this.

Sadly, it doesn't look like it does. There's nothing in LiveBeansView that walks the hierarchy so we need some code that does so.
