Description:

Field propertyResolver in org.springframework.cloud.netflix.eureka.EurekaClientConfigBean required a single bean, but 2 were found:
    - dubboScanBasePackagesPropertyResolver: defined by method 'dubboScanBasePackagesPropertyResolver' in class path resource [org/apache/dubbo/spring/boot/autoconfigure/DubboRelaxedBinding2AutoConfiguration.class]
    - environment: a programmatically registered singleton

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
