Minimal example using Spring HATEOAS's 1.0.0.BUILD-SNAPSHOT version.
When running the tests with mvn clean verify,
loading the context in the test in SpringHateoas100MinimalApplicationTests
fails with a NoUniqueBeanDefinitionException exception:
***************************
APPLICATION FAILED TO START
***************************
Description:
Parameter 0 of method linkDiscoverers in org.springframework.hateoas.config.HateoasConfiguration required a single bean, but 3 were found:
- entityLinksPluginRegistry: defined by method 'entityLinksPluginRegistry' in class path resource [org/springframework/hateoas/config/EntityLinksConfiguration.class]
- relProviderPluginRegistry: defined by method 'relProviderPluginRegistry' in class path resource [org/springframework/hateoas/config/HateoasConfiguration.class]
- linkDiscovererRegistry: defined in null
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
