Question

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是我无法执行.jar文件以查看它是否正常工作........我正在做这和我的朋友一起有一个mac并且它对他来说效果很好，我们有相同的java版本

我试过双击.jar，我试图用命令行打开它

java -jar h2-1.3.170.jar它向我展示了异常

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

Answer 1

要临时修复它，请编辑主机文件并将主机名追加到127.0.0.1 环回地址：

sudo vi /etc/hosts

127.0.0.1 localhost YourHostname

255.255.255.255 broadcasthost

:: 1 localhost

fe80 :: 1％lo0 localhost

192.168.1.3 loki

首先设置它，使用：

sudo scutil --set HostName YourHostname
