Java - UnknownHostException

Question

专用Linux服务器抛出UnknownHostException。

InetAddress addr;
    try {
        addr = InetAddress.getLocalHost();
    } catch (UnknownHostException e) {
        throw new InstantiationError("cannot find hub ip");
    }

Answer 1

您可能没有localhost {win} /etc/hosts（linux）中system32\drivers\etc\hosts的映射

Answer 2

我找到的另一个选项就是这个（我喜欢，因为我现在不必在两个文件中重复主机名）...

java getLocalHost() UnknownHostException /etc/hosts file differs linux api?
