我正在尝试在 opensuse 上使用 h2 数据库,但无法使其工作。 我从官方网站下载了与平台无关的包,然后尝试了几种方法来运行它,但没有成功:
- 使/h2/bin/h2.sh 可执行,然后执行控制台命令 ./h2.sh
- 使用命令 java -jar h2*.jar
- 使用 Play!Framework 命令 h2-browser
所有三个都返回相同的错误:

这是我的 java 版本:
java version "1.7.0_21"
OpenJDK Runtime Environment (IcedTea 2.3.9) (suse-3.37.1-x86_64)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
我的javac版本:
javac 1.7.0_21
更多信息: 我让一个 friend 尝试在 UnbuntuX 上运行它,使用 java -jar h2*.jar 程序,它成功了(我们有相同的 java 版本,省略了 linux 发行版)。 我让另一位 friend 尝试在他的电脑上用Opensuse运行一下,没有成功,和我的错误一样。
谢谢
编辑: 根据需要,etc/hosts文件的内容:
#
# hosts This file describes a number of hostname-to-address
# mappings for the TCP/IP subsystem. It is mostly
# used at boot time, when no name servers are running.
# On small systems, this file can be used instead of a
# "named" name server.
# Syntax:
#
# IP-Address Full-Qualified-Hostname Short-Hostname
#
127.0.0.1 localhost
# special IPv6 addresses
::1 localhost ipv6-localhost ipv6-loopback
fe00::0 ipv6-localnet
ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
最佳答案
我认为问题在于方法 InetAddress.getLocalHost()
由于某种原因在您的环境中不起作用。 H2数据库就是采用这种方法。
问题InetAddress.getLocalHost() throws UnknownHostException中描述了这个问题和可能的答案。
关于H2 数据库无法在 Opensuse 12.2 上运行,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/16610483/
