如果确定是一个纯消费端，并且不想开启 dubbo 端口，可以设置 ```yaml dubbo: application: register-consumer: false ```

> 这个很好，我报名。 @heartarea 非常欢迎。请先参照 GSoC 官方网站流程提交该 Project 的 Proposal，Proposal 内容完全可以是自己对 Dubbo 以及该 Project 的理解，之后我们将基于你提交的 Proposal 进行详细交流。

@yuzhiping There's no `Dubbo Initializer` project available at this moment yet. Customizing one for Dubbo using [spring initializr](https://github.com/spring-io/start.spring.io) is a good way to achieve that.

This issue has been fixed in the latest 2.7.17 and 3.0.11 bugfix versions. Also fixed in the 3.1.0 feature branch.

Please try the latest 3.0.11 release

Already fixed in 2.7.16

@eratolekov Graalvm is an experimental feature in 3.x version that is still under development. Would you like to join and build this feature together with the community?
