Why dubbo 2.7.7 version use spring.application.name but <dubbo:application name="" />?

###Steps to reproduce this issue

1. Use dubbo-spring-boot-starter 2.7.7
2. Set spring.application.name in application.properties
3. Use dubbo xml config:

Why dubbo-admin use step2 name not step3 name when step2 and step3 not same?

Reproduce the behavior with dubbo-spring-boot-starter 2.7.7 using spring.application.name in application.properties and an explicit dubbo XML application name. Compare the value used by dubbo-admin with both configurations; done means the precedence or mismatch is explained and the reported behavior is corrected or documented.
