我一直在使用 InetAddress.getLocalHost().getHostAddress()，如何将其作为字符串获取？

Answer 1

将 ip 作为字符串输出，来自 Justin Waugh 的 answer :

Simply call InetAddress.getByName(String host) passing in your textual IP address.

From the javadoc: The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address.

或者按照 Nambari 的建议使用 InetAddress.getHostAddress()。
