如何使用 Spring Boot Security 修复 Spring Boot Webflux 应用程序中的 'Invalid bean definition with name requestMappingHandlerAdapter' 错误

Question

我想在 spring 引导 webflux 中使用 spring 安全性，但是当我启动应用程序时出现以下错误：

org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'requestMappingHandlerAdapter' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Cannot register bean definition [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration$EnableWebMvcConfiguration; factoryMethodName=requestMappingHandlerAdapter; initMethodName=null; destroyMethodName=(inferred); defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]] for bean 'requestMappingHandlerAdapter': There is already [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=org.springframework.web.reactive.config.DelegatingWebFluxConfiguration; factoryMethodName=requestMappingHandlerAdapter; initMethodName=null; destroyMethodName=(inferred); defined in org.springframework.web.reactive.config.DelegatingWebFluxConfiguration] bound.

gradle 依赖项是：

org.springframework.boot:spring-boot-starter-webflux:2.1.3.RELEASE
org.springframework.boot:spring-boot-starter-security:2.1.3.RELEASE

安全配置包含@EnableWebFluxSecurity 和一个最小的userDetailsService 以及一个SecurityWebFilterChain bean 定义。

    @Bean
    fun userDetailsService(): MapReactiveUserDetailsService {
        val user = User.withDefaultPasswordEncoder()
                .username("user")
                .password("user")
                .roles("USER")
                .build()
        return MapReactiveUserDetailsService(user)
    }

    @Bean
    fun springSecurityFilterChain(http: ServerHttpSecurity): SecurityWebFilterChain {
        http
                .authorizeExchange()
                .anyExchange().authenticated()
                .and()
                .httpBasic().and()
                .formLogin()
        return http.build()
    }

在我看来 spring-boot-starter-webflux 与 spring-boot-starter-security 不兼容。我也试过 spring-boot-starter-security-reactive 库，但它只有 2.0.0.M5 版本。有什么方法可以将 spring-boot-starter-webflux 与 spring-boot-starter-security 一起使用吗？

Answer 1

你能post你的配置bean吗？你有两个吗

@EnableWebflux

和

@EnableWebMvc

?

你是故意依赖覆盖 bean 的吗？ https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.1-Release-Notes#bean-overriding

此致，亚历克斯

Answer 2

今天遇到这个，就是因为这个依赖才发生的
org.springframework.boot:spring-boot-starter-websocket

显然，这个 websocket 的入门包依赖于
org.springframework.boot:spring-boot-starter-web

我删除后，一切恢复正常。
