HATEOAS 설정하기 - swagger와 함께 사용하기 (에러 해결)

Error1.  "The following method did not exist: 'org.springframework.plugin.core.PluginRegistry org.springframework.plugin.core.PluginRegistry.of(java.util.List)'"

 

-> [ compile("org.springframework.plugin:spring-plugin-core:1.2.0.RELEASE") ] 추가

-> swagger configuration에 다음의 Bean 추가

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

 

Error2. "Parameter 0 of method linkDiscoverers in org.springframework.hateoas.config.HateoasConfiguration required a single bean, but 15 were found:" 

 

-> [ implementation 'org.springframework.data:spring-data-rest-hal-browser' ]를 지워보자.
