Thanks for your suggestion. And I will make a test in this case. After I finish my test , I will append my result on this issue.
您的朋友：刘志广 From: Ian Luo Date: 2019-03-08 10:30 To: dev Subject: Re: use xml config in springboot deal to a [Duplicate consumer configs] error It does sound like a bug, we should merge consumer's configuration instead of creating two consumer beans. Would you mind to remove 'id' from <dubbo:consumer /> and give it a try? I also filed an issue[1] to track it.
