issue #451: Duplicate application configs
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：
```text
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" />
```
- main 类
```java
@SpringBootApplication(
exclude = {
DataSourceAutoConfiguration.class,
WebSocketServletAutoConfiguration.class,
JmxAutoConfiguration.class
}
)
@ImportResource(locations = {"classpath:dubbo.xml"})
@Slf4j
public class DubboConsumer270 {
public static void main(String[] args) {
SpringApplication.run(DubboConsumer270.class, args);
}
}

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。。。
