这是我在这里的第一篇文章。我通常会尽力自己找到所有的东西，但我觉得我已经击中了每一堵墙。我很抱歉，如果我不够具体，但希望有人在这里可以帮助我。 我刚开始使用jHipster并成功生成了一个项目，并将它添加到IntelliJ IDEA（使用试用版）。不幸的是，我一直无法让应用程序运行。我继续收到此错误（必须减少以适应字符限制）：JHipster

这些只是我收到的错误的开始。我遵循jHipster网站上列出的所有安装程序，包括安装node.js，npm，bower，yo，grunt，maven，git。我正在尝试为此使用Java 8，但没有看到问题是什么，我无法运行没有错误的未修改生成的项目。我遵循指示将Spring添加到模块项目结构中，但无济于事。该项目将进行编译但不会运行。运行“grunt serve”会启动一个空的服务器并使用mvn spring-boot：运行会关闭上面列出的错误，这与仅尝试运行Java应用程序相同。只是要注意我也尝试使用Eclipse的相同错误。如果有人需要更多的信息来帮助我解决这个错误，我会非常乐意提供任何必要的细节。我可以弄清楚在获取应用程序运行后应该做什么，但是无法达到这一点。如果任何人都可以得到任何帮助，我将不胜感激。感谢大家！
com.zaxxer.hikari.pool.PoolInitializationException连接到本地主机：5432拒绝。检查主机名和端口是否正确，postmaster是否接受TCP/IP连接可能是问题的根源 –
'Connection to localhost：5432 refused'是您本地的postgre实例是否正常运行？ –
所以我从来没有意识到我需要一个运行在我的机器上的postgres实例（初学者的错误），现在将安装它，看看是否解决了这个问题！ – mpgrahov
