Tomcat中的HttpServletRequest.getRemoteAddr()返回IPv6格式的IP地址 [英] HttpServletRequest.getRemoteAddr() in Tomcat returns IPv6 formatted IP address

问题描述

HttpServletRequest.getRemoteAddr()返回IPv6格式的IP地址，但是我想配置它返回IPv4.

HttpServletRequest.getRemoteAddr() in Tomcat returns IPv6 formatted IP address, but I would like to configure it that returns IPv4.

我通过'localhost'访问servlet.如果我通过'127.0.0.1'访问它，则返回IPv4格式的IP地址(请参阅

I access the servlet via 'localhost'. If I access it via '127.0.0.1' then returns IPv4 formatted IP address (see this answer).

环境:

• Windows 7 x64
• Tomcat 6.0.35-windows-x64

我的局域网连接属性: IPv6已被选中，但是如果我将其选中，它也不起作用.

My LAN connection properties: IPv6 is checked off, but it doesn't work neither if I check it on.

推荐答案

尝试将此参数-Djava.net.preferIPv4Stack=true添加到您的tomcat启动命令行中.

try adding this parameter -Djava.net.preferIPv4Stack=true to your tomcat startup commandline.
