项目采用springboot+dubbo，xml文件配置dubbo，配置dubbo application时，该属性放在xml文件中，项目启动就报错，但是配置在application.yml中就能正常启动

报错如下：
Caused by: java.lang.IllegalStateException: Duplicate application configs: <dubbo:application name="xn-demo-provider" valid="true" id="xn-demo-provider" prefix="dubbo.application" /> and <dubbo:application valid="false" qosEnable="false" prefix="dubbo.application" />
