Keycloak с Весенним Облачным Воротом

Я попытался защитить свой Spring Cloud Gateway, используя Keycloak Spring Boot Adapter. Она показывает эту ошибку, как только я добавляю зависимость keycloak-spring-boot-starter: 

**********************************************************

Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway at this time. Please remove spring-boot-starter-web dependency.

Вместо keycloak-spring-boot-starter вы можете использовать официальный клиент Spring Boot OAuth2 / OpenID Connect в зависимости org.springframework.boot:spring-boot-starter-oauth2-client, который хорошо работает с потоками OID Keycloak C, как показано в В блоге Тима Те Бека .

Вы также можете посмотреть образцы весенних облаков на github, esp. sample-gateway-oauth2login. Это проект Gradle, но вы можете легко адаптироваться к Maven.

Я решил эту проблему, исключив Spring-Boot-Start-Web из зависимости адаптера keycloak следующим образом: 

<dependency>
<groupId>org.keycloak</groupId>
<artifactId>keycloak-spring-boot-starter</artifactId>
<exclusions>
    <exclusion>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </exclusion>
</exclusions>
</dependency>

Я не знаю, может ли это вызвать проблемы позже, но сейчас приложение работает.
