Keycloak 4.0.0 Beta 2 with Spring Boot 2

Keycloak-spring-boot-starter（+ keycloak-adapter-bom）を使用しようとすると、エラーが発生します。何か不足していますか？

キークロークが適切に動作しています。 pomファイルからキークロークの依存関係を削除しようとすると、Spring Bootアプリケーションも正常に動作します。

私も同じ問題を抱えていました。必ず、Spring Boot 2スターターを含め、アダプターを直接使用しないでください。

compile 'org.keycloak:keycloak-spring-boot-2-starter:4.0.0.Beta2'

Mavenを使用している場合は、keycloak-spring-boot-2-starter依存関係を追加するだけです。

<!-- https://mvnrepository.com/artifact/org.keycloak/keycloak-spring-boot-2-starter -->
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-spring-boot-2-starter</artifactId>
