[英]JHipster Generation of MS stuck in endless loop

问题描述

TL; DR

我遵循了JHipster网站上有关通过docker安装的步骤。 我生成了一个没有错误的微服务应用程序。 我试图通过gradle运行该应用程序。 它没有完成，因为它不断尝试与Eureka服务器连接。

详细描述

我通过docker在一个名为user-management的文件夹中安装了JHipster。

我进入文件夹〜/ user-management。

创建一个容器并使用以下命令启动它： 

docker container run --name user-management -v ~/Projetos/UserManagementJHipster/user-management:/home/jhipster/app -v ~/.m2:/home/jhipster/.m2 -p 8080:8080 -p 9000:9000 -p 3001:3001 -d -t jhipster/jhipster

输入容器以运行bash命令： 

docker container exec -it user-management bash

在容器内，我创建了一个MS应用程序 

jhipster

我回答了以下问题：

  • 您要创建哪种类型的应用程序？ （使用箭头键）：微服务应用程序

  • 您的应用程序的基本名称是什么？ 用户经理

  • 当您在微服务架构中运行时，您希望服务器在哪个端口上运行？ 它应该唯一以避免端口冲突。 8081

  • 您的默认Java软件包名称是什么？ com.leaf.management.user

  • 您要使用哪个服务发现服务器？ JHipster注册表（使用Eureka，提供Spring Cloud Config支持和监视仪表板）

  • 您要使用哪种身份验证？ 智威汤逊

  • 您要使用哪种类型的数据库？ 的SQL

  • 您要使用哪个生产数据库？ 的MySQL

  • 您想使用哪个开发数据库？ H2具有基于磁盘的持久性

  • 您是否要使用Spring缓存抽象？ 是的，榛果

  • 您是否要使用Hibernate 2级缓存？ 是

  • 您要使用Maven还是Gradle？ 摇篮

  • 您还想使用其他哪些技术？ '使用swagger-codegen进行API首次开发'

  • 您要启用i18n支持吗？ 没有

  • 除了JUnit和Jest，您还要使用哪些测试框架？ 没有

  • 您是否要从JHipster市场安装其他生成器？ 没有

它生成了应用程序
