quarkus-rest-client нельзя использовать с bean-компонентами @ApplicationScoped для образов в машинном коде: в куче не разрешены экземпляры sun.security.provider.NativePRNG

Пример проекта для воспроизведения этой проблемы доступен на Github

Я использую quarkus-rest-client для вызова службы REST из моего приложения Quarkus.

ExampleResource предлагает одну конечную точку http://localhost:8080/echo, которая вызывает https://postman-echo.com/get с использованием RestClient:

@Path("/echo")
public class ExampleResource {

    private final RestClient restClient;

    public ExampleResource(RestClient restClient){
        this.restClient = restClient;
    }

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public Response get() {
        return restClient.get();
    }
}

@ApplicationScoped
public class RestClient {

    private final Client httpClient;

    public RestClient() {
        this.httpClient = ResteasyClientBuilder.newBuilder().build();
    }

    public Response get() {
        return httpClient.target("https://postman-echo.com/get").request().get();
    }
}

Хотя он работает нормально, когда я пытаюсь создать собственный образ, он терпит неудачу:

Если я буду следовать инструкциям из руководства Quarkus относительно этой ошибки, добавление дополнительных параметров сборки в pom по-прежнему не удается:

Проблема возникает, когда RestClient определен как @ApplicationScoped компонент. Если я изменю его так, чтобы он был создан, создание собственного образа не будет иметь никаких проблем:

@Path("/echo")
public class ExampleResource {

    private final RestClient restClient;

    public ExampleResource(){
        this.restClient = new RestClient();
    }

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public Response get() {
        return restClient.get();
    }
}

public class RestClient {

    private final Client httpClient;

    public RestClient() {
        this.httpClient = ResteasyClientBuilder.newBuilder().build();
    }

    public Response get() {
        return httpClient.target("https://postman-echo.com/get").request().get();
    }

}

Вопрос в том, как я могу определить RestClient как @ApplicationScoped компонент и иметь возможность сгенерировать собственный образ?

Как указано здесь, вы не используете клиент MicroProfile REST, но вместо этого клиент JAX-RS.

В любом случае вы можете заставить свой код работать в собственном режиме, изменив класс RestClient на:

@ApplicationScoped
public class RestClient {

    private Client client;

    public Response get() {
        return getClient().target("https://postman-echo.com/get").request().get();
    }

    private Client getClient() {
        if (client == null) {
            client = ResteasyClientBuilder.newBuilder().build();
        }
        return client;
    }

}

а также добавив:

quarkus.native.enable-https-url-handler=true

to application.properties
