Answer 1

Spring is telling you the problem
org.springframework.hateoas.config.HateoasConfiguration required a single bean,
but 15 were found:
Which means that there are 15 methods that return a bean that fits HateoasConfiguration.
Who are those bastards?
Spring continues right after with the list:
- 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]
The list might be not so clear or familiar as it might be that some of these methods are defined by the framework.
So what can be done?
Spring is suggesting a solution:
Action:
Consider marking one of the beans as #Primary,
updating the consumer to accept multiple beans,
or using #Qualifier to identify the bean that should be consumed
Does it mean that I need to reconfigure my #Beans?
Not necessarily. First try to see if someone else faced the same problem.
You may find the solution there.
