OpenApi

Question

我正在使用功能控制器将 Swagger 添加到我的 Spring Webflux 服务中。首先我收到这个错误：

Description: The bean 'swaggerWelcome', defined in class path resource [org/springdoc/webflux/ui/SwaggerConfig.class], could not be registered. A bean with that name has already been defined in class path resource [org/springdoc/webmvc/ui/SwaggerConfig.class] and overriding is disabled.

Action:

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

所以我将 spring.main.allow-bean-definition-overriding=true 添加到我的 application.properties 文件中。

现在我收到这个错误：

Description:

Parameter 1 of method swaggerWebMvcConfigurer in org.springdoc.webmvc.ui.SwaggerConfig required a bean of type 'org.springdoc.webmvc.ui.SwaggerIndexTransformer' that could not be found.

Action:

Consider defining a bean of type 'org.springdoc.webmvc.ui.SwaggerIndexTransformer' in your configuration.

        </dependency>

    </dependencies>
</project>

application.properties 文件包含：

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

有没有办法避免这种配置？ SwaggerIndexTransformer 的用途是什么？因为在网站 https://springdoc.org/#getting-started 他们说“不需要额外的配置”。

Answer 1

错误是在pom文件中唯一的依赖应该是springdoc-openapi-webflux-ui

OpenApi - 需要找不到类型 'org.springdoc.webmvc.ui.SwaggerIndexTransformer' 的 bean

OpenApi - required a bean of type 'org.springdoc.webmvc.ui.SwaggerIndexTransformer' that could not be found

spring-webflux

api-doc

springdoc-openapi-ui
