RESTEASY003145：content-type application / jsonおよびtype class org.keycloak.representations.AccessTokenResponseのMessageBodyReaderが見つかりません

Keycloak REST APIをテストしようとしています。バージョン2.1.0.Finalをインストールしました。SSLを使用してブラウザから問題なく管理者にアクセスできます。

上記のコードを使用しています：

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();

そしてエラーが発生しました：

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

上記の依存関係を追加しましたが、私の問題は解決しません：

    <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>

手がかりはありますか？

解決しました!! org.jboss.resteasy.plugins.providers.jackson.ResteasyJacksonProviderをMETA-INF/services/javax.ws.rs.ext.Providersファイルに追加して、実行可能なjarを実行する必要があります。

この問題を修正するために依存関係を使用しました

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

または、プロキシを使用してクライアントを作成する場合は、前にプロバイダーファクトリを初期化することをお勧めします。

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

Dmitryがここで指摘した を追加すると、次の警告が表示されます。

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

おそらく ベーコンが言ったように 依存関係を追加するだけでプロバイダーは自動的に登録されます：

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

MatteoM が指摘する問題がありました。私はmaven-shade-pluginとtransformesタグで解決しました。多分それは誰かを助ける。
