Invalid bean definition with name 'triage'; @Bean definition illegally overridden by existing bean definition:

Question

I have two RestTemplates in ServiceConfiguration.class:

@Configuration
public class ServiceConfiguration {

    @Bean(name = "dms")
    public static RestTemplate defaultDmsRestTemplate() throws URISyntaxException {

            return RestTemplateBuilder.builder().withProxy().build(dmsProxyUrl, "", "");
    }

    @Bean(name = "triage")
    public static RestTemplate defaultTriageRestTemplate() throws URISyntaxException {
            return RestTemplateBuilder.builder().withProxy().withCookies(true).build(triageProxyUrl, proxyUsername,
                    proxyPassword);

    }
}

And on their injecting they have declared @Qualifiers with their names:

@Service
public class ClientService {

    @Autowired
    @Qualifier("triage")
    private RestTemplate triageRestTemplate;

   @Autowired
    @Qualifier("dms")
    private RestTemplate dmsRestTemplate;

}

But I obtain error during app initialization:

org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'triage' defined in class path resource [de/triage/configurations/ServiceConfiguration.class]: @Bean definition illegally overridden by existing bean definition: Generic bean: class [de.triage.Triage]; scope=singleton; abstract=false; lazyInit=null; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null

I don't really know how to handle this isuue. I can't also enable overriding.

Answer 1

From the error message, it seems there is a conflict with another bean named triage after the class name de.triage.Triage. Try giving the bean a different name.
