用Java替代默认的DNS名称解析 [英] Replace default DNS name resolution in Java

问题描述

我想更改JVM在HttpURLConnections中解析域名的方式。

而不是通过默认TCP / IP堆栈去DNS服务器，我想写我自己的代码来解决域名。

有没有办法来替换默认名称解析机制？

解决方案

我不知道是否可以工作，但有系统属性

System.setProperty（sun.net.spi .nameservice.nameservers，localhost）;
System.setProperty（sun.net.spi.nameservice.provider.1，dns，sun）;

也许如果你有你的java应用程序在dns端口上打开一个端口（53），并自动处理请求。

当然，如果当前机器上已经有一个dns服务器， p>

I'd like to change the way the JVM resolves domain names in HttpURLConnections.

Instead of going to DNS servers through the default TCP/IP stack I wanted to write my own code to resolve domain names.

Is there a way to replace the default name resolution mechanism?

解决方案

i have no idea if it would work, but there are system properties

System.setProperty("sun.net.spi.nameservice.nameservers", localhost); System.setProperty("sun.net.spi.nameservice.provider.1", "dns,sun");

perhaps if you have your java application open a port on the dns port (53) and process requests yourself.

Of course this falls down if there is a dns server already on the current machine.
