RESTEASY003145: Impossible de trouver un MessageBodyReader de type de contenu application/json et une classe de type org.keycloak.representations.AccessTokenResponse

J'essaie de tester l'API Keycloak REST . J'ai installé la version 2.1.0.Final . Je peux accéder à l'administrateur via un navigateur avec SSL sans problème.

J'utilise le code ci-dessus:

Keycloak keycloakClient = KeycloakBuilder.builder()
.serverUrl("https://keycloak.intra.rps.com.br/auth")
.realm("testrealm")
.username("development")
.password("development")
.clientId("admin-cli")
.resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).build())
.build();
List<RealmRepresentation> rr = keycloakClient.realms().findAll();

Et j'ai eu l'erreur:

javax.ws.rs.ProcessingException: RESTEASY003145: Unable to find a MessageBodyReader of content-type application/json and type class org.keycloak.representations.AccessTokenResponse

J'ai ajouté les dépendances ci-dessus, mais ne résous pas mon problème:

    <dependency>
            <groupId>org.jboss.resteasy</groupId>
            <artifactId>resteasy-client</artifactId>
            <version>3.0.19.Final</version>
    </dependency>
    <dependency>
            <groupId>org.jboss.resteasy</groupId>
            <artifactId>resteasy-jackson-provider</artifactId>
            <version>3.0.19.Final</version>
    </dependency>

Des indices?

J'ai résolu !! Vous devez ajouter org.jboss.resteasy.plugins.providers.jackson.ResteasyJacksonProvider au fichier META-INF/services/javax.ws.rs.ext.Providers, puis exécuter votre fichier jar exécutable.

J'ai utilisé la dépendance pour résoudre ce problème

   <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jackson2-provider</artifactId>
        <version>3.1.0.Final</version>
    </dependency>

Ajouter ce que Dmitry a signalé ici pour moi provoque l’avertissement suivant:

WARN: RESTEASY002155: Provider class org.jboss.resteasy.plugins.providers.jackson.ResteasyJackson2Provider is already registered.  2nd registration is being ignored.

Probablement comme dit Bacon le fournisseur est automatiquement enregistré en ajoutant simplement la dépendance:

    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jackson2-provider</artifactId>
        <version>${resteasy.version}</version>
    </dependency>

Ou si vous créez un client avec proxy, il est préférable d’initialiser la fabrique du fournisseur 

    ResteasyProviderFactory instance=ResteasyProviderFactory.getInstance();
    RegisterBuiltin.register(instance);
    instance.registerProvider(ResteasyJackson2Provider.class);
