我正在尝试为我的 java 应用程序构建一个 H2 数据库，我认为它正在工作，但我无法执行 .jar 文件来查看它是否工作......我正在用我的朋友，他有一台 mac，对他来说运行良好，我们有相同的 java 版本

我尝试通过双击 .jar 并尝试使用命令行打开它

java -jar h2-1.3.170.jar它向我展示了那个例外

IO Exception: "java.net.UnknownHostException: dhcp-10-231-195-255: dhcp-10-231-195-255: nodename nor servname provided, or not known" [90028-170]

要临时修复它，请编辑主机文件并将您的主机名附加到127.0.0.1 环回地址：

sudo vi /etc/hosts

127.0.0.1 本地主机您的主机名

255.255.255.255 广播主机

::1 本地主机

fe80::1%lo0 本地主机

192.168.1.3 洛基

首先设置它，使用：

sudo scutil --set HostName YourHostname

如果你用谷歌搜索这个例外，你会发现其他人也有同样的问题。这可能是由Java 7 中的错误引起的。
