如何用Java代码来获得访问者的Ip地址和时间和访问人数，要用Java中的action来实现。（如果时间在5分钟之内访问量不变，否则加1）

Answer 1

 public String getIpAddr(HttpServletRequest request) { 
String ip = request.getHeader("x-forwarded-for"); 
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 
ip = request.getHeader("Proxy-Client-IP"); 
} 
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 
ip = request.getHeader("WL-Proxy-Client-IP"); 
} 
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 
ip = request.getRemoteAddr(); 
} 
return ip; 
}
