JSP获取客户端的IP地址的方法

//声明以下方法
<%!
public String getRemortIP(HttpServletRequest request) { 
    if (request.getHeader("x-forwarded-for") == null) { 
        return request.getRemoteAddr(); 
    } 
    return request.getHeader("x-forwarded-for"); 
}%> 

在html部分添加以下内容

<form name="adminloginForm" method="post" action="test.do"> 
   <td align="center"><%=getRemortIP(request)%></td> 
   <input type="submit" name="Submit" value="确定"> 
</form>
