为什么 HATEOAS 在 Swagger 2.x 启动期间开始为 spring-boot 版本 >= 2.2.x 创建问题?

我将我的项目从spring-boot 2.1.9移动到2.2.0。

在开始项目时,我面临着以下消息。error

Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'org.springframework.plugin.core.PluginRegistry<org.springframework.hateoas.client.LinkDiscoverer, org.springframework.http.MediaType>' available: expected single matching bean but found 17: modelBuilderPluginRegistry,modelPropertyBuilderPluginRegistry,typeNameProviderPluginRegistry,syntheticModelProviderPluginRegistry,documentationPluginRegistry,apiListingBuilderPluginRegistry,operationBuilderPluginRegistry,parameterBuilderPluginRegistry,expandedParameterBuilderPluginRegistry,resourceGroupingStrategyRegistry,operationModelsProviderPluginRegistry,defaultsProviderPluginRegistry,pathDecoratorRegistry,apiListingScannerPluginRegistry,relProviderPluginRegistry,linkDiscovererRegistry,entityLinksPluginRegistry

Description:


Parameter 0 of method linkDiscoverers in org.springframework.hateoas.config.HateoasConfiguration 
required a single bean, but 17 were found:
- modelBuilderPluginRegistry: defined in null
- modelPropertyBuilderPluginRegistry: defined in null
- typeNameProviderPluginRegistry: defined in null
- syntheticModelProviderPluginRegistry: defined in null
- documentationPluginRegistry: defined in null
- apiListingBuilderPluginRegistry: defined in null

- defaultsProviderPluginRegistry: defined in null
- pathDecoratorRegistry: defined in null
- apiListingScannerPluginRegistry: defined in null
- relProviderPluginRegistry: defined by method 'relProviderPluginRegistry' in class path resource [org/springframework/hateoas/config/HateoasConfiguration.class]
- linkDiscovererRegistry: defined in null
- entityLinksPluginRegistry: defined by method 'entityLinksPluginRegistry' in class path resource [org/springframework/hateoas/config/WebMvcEntityLinksConfiguration.class]

是什么导致了这个问题?

注意:我没有在我的文件中使用HATEOAS。pom.xml

答案 1

我在应用程序中遇到了此问题。Swagger + HATEOASspring-boot

下面给出了修复程序(编辑您的 Swagger 配置类):

@Configuration
@EnableSwagger2
public class SwaggerConfiguration {

    @Bean
    public LinkDiscoverers discoverers() {
        List<LinkDiscoverer> plugins = new ArrayList<>();
        plugins.add(new CollectionJsonLinkDiscoverer());
        return new LinkDiscoverers(SimplePluginRegistry.create(plugins));

    }
}

答案 2

对我来说,这个链接帮助:https://github.com/spring-projects/spring-hateoas/issues/731

简而言之,我添加到我的依赖项中:

<dependency>
    <groupId>org.springframework.plugin</groupId>
    <artifactId>spring-plugin-core</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>
