Java InetAddress.getByName和/ etc / hosts
[英]Java InetAddress.getByName & /etc/hosts
问题描述
With 
用
java -version
java version "1.8.0_72"
Java(TM) SE Runtime Environment (build 1.8.0_72-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.72-b15, mixed mode)
And aliases in the host file like 和主机文件中的别名一样
10.0.0.4 bar.com
10.0.0.5 a-a.foo.com a-b.foo.com a-c.foo.com ...
Im able to resolve bar.com with InetAddress.getByName("bar.com"). 我无法使用InetAddress.getByName（“ bar.com”）解析bar.com。 But If the line is getting bigger like 30 hosts and longer than 767 Chars a UnknownHostException is thrown. 但是，如果该行越来越大，例如30台主机，并且长度超过767个字符，则会引发UnknownHostException。
How to let Java handle this line as should? 如何让Java应对这一行？
For example "ping bar.com" is doing the lookup correctly. 例如，“ ping bar.com”正确执行了查找。

There's a limit on the number of aliases per ip address depending on your system. 每个ip地址的别名数量受到限制，具体取决于您的系统。 Try adding another line for each x aliases where x is max number of aliases for your system which is 34 in your case. 尝试为每个x别名添加另一行，其中x是系统的最大别名数（在您的情况下为34）。
