Why HATEOAS starts creating issue for spring-boot version >= 2.2.x during startup with Swagger 2.x?

Question

I moved my project from spring-boot 2.1.9 to 2.2.0.

While starting the project, I am facing the below error messages.

Caused by: org.sprin         


        

Answer 1

I am using springdoc-openapi and after having encountered this problem similar to the one mentioned here:

Description:

Parameter 0 of method linkDiscoverers in org.springframework.hateoas.config.HateoasConfiguration required a single bean, but 3 were found:
    - 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]


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

I just add this dependency in my pom file

    org.springframework.hateoas
    spring-hateoas
    1.1.1.RELEASE

hope that this can help someone
