这是我在这里发表的第一篇文章。我一般都试图找到自己的一切，但我觉得我已经碰到了所有可能的墙。如果我不够具体但我希望有人可以帮助我，我道歉。 我刚开始使用jHipster并成功生成了一个项目，并将其添加到IntelliJ IDEA（使用试用版）。不幸的是我无法运行应用程序。我继续收到此错误（必须减少以适应字符约束）：

这些只是我收到的错误的开始。我已经按照jHipster网站上列出的所有设置程序进行了操作，包括安装node.js，npm，bower，yo，grunt，maven，git。我试图使用Java 8，但不知道问题是我无法运行未更改的生成项目。我按照说明将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。跑步＆＃34;咕噜声＆＃34;启动一个空的服务器并使用mvn spring-boot：run close与上面列出的错误一样，只是尝试运行Java应用程序。请注意，我也试图使用具有相同错误的Eclipse。如果有人需要更多信息来帮助我解决这个错误，我非常乐意提供任何必要的细节。我可以弄清楚在运行应用程序后要做什么，但却无法达到目的。如果有人可以提供任何帮助，我不仅仅是欣赏它。谢谢大家！

看起来错误在于连接到postgres服务器。确保您运行的postgres具有application.yml中定义的数据库名称。如果您不想使用postgres，可以将jHipster配置为使用嵌入式H2数据库。
这是相关错误跟踪的一部分：

the hostname and port are correct and that the postmaster is accepting
TCP/IP connections.
