Duplicate application configs

[foreveryang321]

环境
dubbo-2.7.0
dubbo-spring-boot-starter-2.7.0

同时使用xml作为dubbo的配置时，会出现以下异常：

Caused by: java.lang.IllegalStateException: Duplicate application configs: <dubbo:application name="dubbo-consumer-2.7.x" valid="true" id="dubbo-consumer-2.7.x" prefix="dubbo.application" /> and <dubbo:application valid="false" prefix="dubbo.application" />

                JmxAutoConfiguration.class

API配置也会报错，貌似只能通过properties配置。今天刚学也踩到这个坑了。。。

@Configuration
public class DubboConfiguration {

    @Bean
    public ApplicationConfig applicationConfig() {
        ApplicationConfig applicationConfig = new ApplicationConfig("provider");
        return applicationConfig;
    }

    @Bean
    public RegistryConfig registryConfig() {
        RegistryConfig registryConfig = new RegistryConfig();
        registryConfig.setAddress("zookeeper://127.0.0.1:2181");
        registryConfig.setClient("curator");
        return registryConfig;
    }

    @Bean
    public ProtocolConfig protocolConfig() {
        ProtocolConfig protocolConfig = new ProtocolConfig();
        protocolConfig.setPort(20880);
        protocolConfig.setName("dubbo");
        return protocolConfig;
    }
}

application-dev.properties

# dubbo-provider.properties

server.port=9090
#dubbo.application.default=false
#dubbo.application.name=provider
#dubbo.registry.address=zookeeper://127.0.0.1:2181
#dubbo.protocol.name=dubbo
#dubbo.protocol.port=20880
#spring.main.allow-bean-definition-overriding=true

应该默认只读取 properties,同遇到这个问题
