を私はネットで検索このsolutionが見つかりましたが、それはうまくいきません。また、そのディスカッション（私はリンクを投稿するためにもっと評判が必要です：http：/lists.jboss.org/pipermail/keycloak-user/2014-November/001120.html）問題の原因を説明しますが、私は解決策を見つけることはできません。 誰でも助けてください。

Answer 1

Keycloak Admin Client（バージョン1.9.0以降）は、そのままresteasy-jackson2-provider JSONプロバイダをサポートしています。これにより、この問題は解決されます。

あなたのpomにresteasy-jackson-providerの代わりに使用してください。
