如何用Java代碼來獲得訪問者的Ip地址和時間和訪問人數，要用Java中的action來實現。（如果時間在5分鐘之內訪問量不變，否則加1）

最佳回答：

 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; 
}
