我试过使用Keycloak Spring Boot Adapter来保护Spring Cloud Gateway的安全，但我一添加keycloak-spring-boot-starter依赖项，它就显示了这个错误：

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

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

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

这是堆栈跟踪：

您可以使用依赖项org.springframework.boot:spring-boot-starter-oauth2-client中的Sping Boot 官方OAuth2/OpenID Connect客户端来代替keycloak-spring-boot-starter，该客户端可以很好地与Tim te Beek's blog post上所示的Keycloak OIDC流配合使用。
您也可以看看spring-cloud samples on github, esp. sample-gateway-oauth2login，它是一个Gradle项目，但您可以轻松地适应Maven。

我通过从keycloak适配器依赖项中排除spring-boot-started-web来解决这个问题，如下所示

<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>

我不知道这是否会导致以后的问题，但现在的应用程序正在运行。

当我排除spring-boot-starter-web以解决错误消息Auth在我的项目中变为禁用时，我尝试通过添加以下依赖项将网关服务器配置为身份验证和授权服务器

<dependency>
        <groupId>org.keycloak</groupId>
        <artifactId>keycloak-spring-boot-starter</artifactId>
        <version>20.0.2</version>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
