jsp页面中如何获取访问此网页的主机ip地址？

Answer 1

你要取ip是吧，用request.getRemoteAddr() 就够了

Answer 2

使用request对象的以下三个方法可以得到相关的信息，不过如果中间有代理服务器的话，则不适用了。以下是API文档中的说明：
String getRemoteAddr()
Returns the Internet Protocol (IP) address of the client or last proxy that sent the request.

String getRemoteHost()
Returns the fully qualified name of the client or the last proxy that sent the request.

int getRemotePort()
Returns the Internet Protocol (IP) source port of the client or last proxy that sent the request.
