今天springboot整合swagger2出现了这个错误，感到无从下手，经过一番查询才了解到可能是版本不对，自己的springboot版本为2.3.3而swagger的版本是2.2.2版本太低了，不对付。
Description:
Parameter 0 of method linkDiscoverers in org.springframework.hateoas.config.HateoasConfiguration required a single bean, but 15 were found: - modelBuilderPluginRegistry: defined in null - modelPropertyBuilderPluginRegistry: defined in null - typeNameProviderPluginRegistry: defined in null - documentationPluginRegistry: defined in null - apiListingBuilderPluginRegistry: defined in null - operationBuilderPluginRegistry: defined in null - parameterBuilderPluginRegistry: defined in null - expandedParameterBuilderPluginRegistry: defined in null - resourceGroupingStrategyRegistry: defined in null - operationModelsProviderPluginRegistry: defined in null - defaultsProviderPluginRegistry: defined in null - pathDecoratorRegistry: 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]
更改swagger2的依赖版本后完美解决。
版本更改为2.9.2，解决
