Java获取本机IP地址方法。

今天在代码中遇到了Java获取本机IP的需求，网上搜了好多，决定记录下来，方便以后使用。

/**
	 * 获取本机IP 方法一
	 * 传递request 对象进来
	 * @param request
	 * @return
	 */
	public static String getRemortIP(HttpServletRequest request) { 
		  if (request.getHeader("x-forwarded-for") == null) { 
		   return request.getRemoteAddr(); 
		  } 
		  return request.getHeader("x-forwarded-for"); 
		 } 

/**
	 * 获取本机IP 方法二
	 * 传递request 对象进来
	 * @param request
	 * @return
	 */
	public static String getRemortIP(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; 
	   }
