我正在尝试运行以下vertx教程，但坚持这个例外。

我试图只运行单一服务或整个项目异常即将发生。
我缺少任何码头设置？

答案 0 :(得分：4)
经过大量调试后我终于发现最近版本的vertx解决了主机问题。因此，通过此选项，我们可以禁用默认情况下为ON的disableDnsResolver。它对我来说很好用
CMD ["java -Dvertx.disableDnsResolver=true -jar account-microservice-fat.jar -cluster -conf docker.json"]
如果尝试运行以上示例，则需要在everymicroservice的DockerFile中添加-Dvertx.disableDnsResolver = true
