Actuator EndpointWebExtension issue

[burghategaurao]

When I am trying to implement actuator EndpointWebExtension for HealthEndpoint, it throws Error as

Caused by: java.lang.IllegalStateException: Found multiple extensions for the endpoint bean healthEndpoint

So Question is

1. Do Spring support multiple extension for Endpoint?
2. Do Spring supports extension for inbuild endpoint like HeathEndpoint or extension is only supported for Custom Actuator endpoints.

A single web extension is supported per endpoint. Spring Boot already auto-configures a HealthEndpointWebExtension for the health endpoint so you cannot provide an additional web extension for it. You can replace the auto-configured extension by providing your own bean that is a sub-class of HealthEndpointWebExtension as this will cause the auto-configured extension to back off.

I have similar issue with duplicates.

Caused by: java.lang.IllegalStateException: Unable to map duplicate endpoint operations: [web request predicate GET to path 'health' produces: application/vnd.spring-boot.actuator.v3+json,application/vnd.spring-boot.actuator.v2+json,application/json, web request predicate GET to path 'health/{*path}' produces: application/vnd.spring-boot.actuator.v3+json,application/vnd.spring-boot.actuator.v2+json,application/json] to healthEndpoint (healthEndpointWebExtension)

But in my case there is sub-class of HealthEndpointWebExtension:

@EndpointWebExtension(endpoint = HealthEndpoint.class)
public class HealthEndpointWebExtension extends org.springframework.boot.actuate.health.HealthEndpointWebExtension

Despite that fact spring tries to create auto-configured and custom HealthEndpointWebExtension.

@StarReider Our auto-configuration does use @ConditionalOnMissingBean so something unexpected must be going on. Could you please open a new issue and attach a sample project that replicates the problem.
