Add ability to hide rest endpoints from OpenAPI schema / Swagger

[rsvoboda]

Description

I'm unable to hide JAXRS methods in OpenAPI schema / Swagger.

For endpoints that are experimental or legacy ones I don't want them to be part of the generated schema. That schema serves as public contract in many cases.

I found io.swagger.v3.oas.annotations.Hidden annotation, but no equivalent of it in Quarkus OpenAPI extension.
SB has ways to hide endpoints from the generated document even without using @Hidden annotation.

Please add ability to hide rest endpoints from OpenAPI schema / Swagger.

We do not support the swagger annotations. Please use MicroProfile OpenAPI

[phillip-kruger]

Example: if this is an operation you can do @Operation(hidden=true) (use package org.eclipse.microprofile.openapi.annotations)

Thanks @phillip-kruger, this helps a lot!

As stated in description of this issue, I was able to find a lot of resources describing swagger way and even more resources for SB. I looked into openapi for examples, I scraped https://github.com/eclipse/microprofile-open-api/blob/main/spec/src/main/asciidoc/microprofile-openapi-spec.asciidoc too, but nothing popped up.

https://quarkus.io/guides/openapi-swaggerui guide could be extended with examples how to hide methods/endpoints and fields of returrned objects.
Seems that we are expecting that people are quite familiar with Eclipse MicroProfile OpenAPI and all the constructs it allows, but in reality there are not many resources that people can use.

Agree, we can definitely update the docs. We also have on our to-do list to add support for swagger annotations, but it has never really been a priority. See smallrye/smallrye-open-api#752

@rsvoboda this is already possible, but it is nowhere documented and I found it by accident.

So it works something like this:

import io.quarkus.runtime.StartupEvent;
import io.quarkus.runtime.rest.DisabledRestEndpoints;
import jakarta.enterprise.event.Observes;
import org.eclipse.microprofile.config.inject.ConfigProperty;

import java.util.HashMap;
import java.util.List;

/**
 * Removes the internal api's from the Swagger UI & OpenAPI yaml.
 */
public class SwaggerUiConfig {

    @ConfigProperty(name = "swagger-ui.show-internal-apis")
    boolean showInternalApis;

    @ConfigProperty(name = "swagger-ui.disabled-paths")
    List<String> disabledPaths;

    public void init(@Observes StartupEvent event) {
        if (!this.showInternalApis) {
            var result = new HashMap<String, List<String>>();
            this.disabledPaths.forEach(path -> result.put(path, List.of("DELETE", "POST", "PATCH", "PUT")));
           DisabledRestEndpoints.set(result);
       }
   }
}

application.properties:

mp.openapi.filter=io.quarkus.smallrye.openapi.runtime.filter.DisabledRestEndpointsFilter

swagger-ui.show-internal-apis=false
%dev.swagger-ui.show-internal-apis=true
swagger-ui.disabled-paths=/v1/admin/fruits,/v1/management/fruits/

Note that the disabled-path names should match the path names in your openapi.yml.

I hope this helps you.

Thanks @Serkan80! It's good there a way to achieve this right now.
Quarkus should provide simpler way through annotation.

[Serkan80]

@rsvoboda I'm afraid that to achieve this through annotation, is going to be hard, because this needs to be a part of the MP OpenApi specification. So everyone needs to agree on it, and this can take a while. For the time being, this solution is good enough for me.

[MikeEdgar]

Have you looked at using mp.openapi.scan.exclude.classes or mp.openapi.scan.exclude.packages to skip the resources implementing the endpoints you'd like to hide?

[phillip-kruger]

@rsvoboda can we close this ?

[rsvoboda]

mp.openapi.scan.exclude.classes and mp.openapi.scan.exclude.packages work well

I've created #43593 to reference the spec from the guide so people can find mp.openapi config options more easily
