InetAddress java 8没有获取主机名 [英] InetAddress java 8 is not getting the hostname

问题描述

InetAddress.getLocalHost（）。getHostName（）不再获取HostName的名称，因为我切换到java 8 ...

InetAddress.getLocalHost().getHostName() is no more getting the name of the HostName since I switched to java 8 ...

使用jdk1.8 InetAddress.getLocalHost（）。getHostName（）返回localhost。之前（当我使用jdk1.6时）它根据网络配置给我正确的主机名（即ACTION03）：

with the jdk1.8 the InetAddress.getLocalHost().getHostName() returns "localhost". Before (when I was using jdk1.6) it gives me the right hostname (which is "ACTION03") according to the network config :

cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=ACTION03

任何帮助？

推荐答案

在JDK中触发的类似错误。

据我所知，他们更改了默认解决程序。

What I understand is that they changed default resolution process.

他们尊重 /中的配置etc / nsswitch.conf 其中主机配置为 / etc / hosts ，它为名称解析提供了主要优先级。

They honor configuration in /etc/nsswitch.conf where hosts are configured for /etc/hosts that gives it main priority for name resolution.

通常 / etc / hosts 有 127.0.0.1 localhost 为主机提供名称 localhost

Usually /etc/hosts has record for 127.0.0.1 localhost that provide name for host localhost
