使用 spring-boot-admin-server 创建名为“conversionServicePostProcessor”的 bean 时出错

Question

我试图为我的应用程序启用 Spring 引导管理服务器。默认设置工作得很好，但是当我尝试启用安全性时，出现以下错误：

APPLICATION FAILED TO START

Description:

The bean 'conversionServicePostProcessor', defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/security/config/annotation/web/reactive/WebFluxSecurityConfiguration.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

Process finished with exit code 1

我正在使用 spring-boot-admin-starter-server 的最新 SNAPSHOT 版本 (2.2.0-SNAPSHOT)。这是我的安全配置：

@EnableAdminServer
@EnableWebFluxSecurity
@Configuration(proxyBeanMethods = false)
class AdminServerSecurityConfigurations(val adminServerProperties: AdminServerProperties) {

    @Bean
    fun adminServerSecurityWebFilterChain(http: ServerHttpSecurity): SecurityWebFilterChain = http
            // @formatter:off
            .authorizeExchange()
                .pathMatchers("${adminServerProperties.contextPath}/assets/**").permitAll()
                .pathMatchers("${adminServerProperties.contextPath}/login").permitAll()
                .anyExchange().authenticated().and()
            .formLogin().loginPage("${adminServerProperties.contextPath}/login").and()
            .logout().logoutUrl("${adminServerProperties.contextPath}/logout").and()
            .httpBasic().and()
            // @formatter:on
            .csrf().disable()
            .build()


    @Bean
    fun notifyLogger(instanceRepository: InstanceRepository) = LoggingNotifier(instanceRepository)

}

我找到了更新文档的拉取请求：https://github.com/spring-projects/spring-boot/issues/14069

For Reactive WebSockets, {spring-reference}web-reactive.html#webflux-websocket[Spring WebFlux] offers rich support, which is accessible through the spring-boot-starter-webflux module. See the spring-boot-sample-websocket-reactive sample project to see how WebSockets may be implemented using Spring WebFlux.

原来使用webflux和websocket会导致冲突

同样在这个拉取请求中被拒绝解决冲突 https://github.com/spring-projects/spring-boot/issues/14810

对于反应式 websocket，请参阅此示例 https://www.baeldung.com/spring-5-reactive-websockets

我遇到了同样的问题，可以通过添加

来解决

spring.main.allow-bean-definition-overriding=true

给我的 application.properties.

听起来像是一种解决方法，而且只有当我将其部署为 WAR 时才需要它——作为一个独立的应用程序，从未发生过异常。

我也遇到了这个错误，在重新导入所有 Maven 项目（Intellij IDE）后它对我来说工作正常。这是我对这个问题的详细输入 here
