clientRegistrationRepository 不能是 null

Question

Keycloak OAuth 2.0 clientRegistrationRepository 不能是null。

您好，在我的应用程序中尝试使用 OAuth 2.0 时发现了一个问题。 启动后就失败了。 信息：

上下文初始化期间遇到异常 - 取消刷新尝试：org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为“org.springframework.security.config.annotation.web.reactive.WebFluxSecurityConfiguration”的bean时出错：通过方法“setSecurityWebFilterChains”表达的依赖关系不满足' 参数 0; 嵌套异常是 org.springframework.beans.factory.BeanCreationException：在 class 路径资源 [com/microservices/apigateway/security/SecurityConfig.class] 中定义的名为“springSecurityFilterChain”的 bean 创建时出错：通过工厂方法实例化 Bean 失败； 嵌套异常是 org.springframework.beans.BeanInstantiationException：无法实例化 [org.springframework.security.web.server.SecurityWebFilterChain]：工厂方法 'springSecurityFilterChain' 抛出异常； 嵌套异常是 java.lang.IllegalArgumentException：clientRegistrationRepository 不能是 null

在 .net 中找不到有关此问题的可能性质的任何信息。

安全配置

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.web.server.SecurityWebFilterChain;


@Configuration
@EnableWebFluxSecurity
public class SecurityConfig {
    @Bean
    public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
        http
                    .authorizeExchange()
                    .pathMatchers("/actuator/**")
                    .permitAll()
                .and()
                    .authorizeExchange()
                    .anyExchange()
                    .authenticated()
                .and()
                    .oauth2Login() // to redirect to oauth2 login page.
        ;

        return http.build();
    }
}
