无法启动用JHipster生成的后端

我已经使用JHipster版本6.10.1生成了一个后端应用程序 对于我使用的第二代：

jhipster——跳过前端-db MySQL-auth JWT

应用程序已创建为fallows：

• 微服务应用
• 用户SpringWebFlux
• 应用程序的名称
• 港口
• 包装
• JHipster注册表（使用Eureka，提供Spring云配置支持和监控仪表盘）
• JWT认证
• MySQL数据库
• 马文
• 使用Elasticsearch的搜索引擎
• i18n：是的
• 黄瓜

每次尝试启动应用程序时，我都会从eureka收到此错误：

我在这里缺少什么？

您启动了注册表吗？这是我第一次尝试使用Jhipster，根据我在文档中阅读的内容，注册表应该由生成的后端启动。但从你所说的来看，我发现这并不完全正确，我将手动启动注册表jar。像mysql和elasticsearch这样的注册表是外部应用程序，所以通常你从src/main/docker文件夹中使用docker compose启动它们，如自述文件中所述。尽管对于注册表来说可能有点不同，因为您希望管理您的中心配置。如果这是你第一次尝试使用JHipster，我建议你从没有注册表的简单选项开始，当然也可以不使用elasticsearch，这取决于你的需求。谢谢@GaëlMarziou。我设法设置我的环境。刚开始的时候我有点困惑，但现在一切都好了。谢谢你抽出时间。
