java web判断服务器是否是本机

1,如何获取浏览器的ip

Java代码   
/*** 
     * 获取客户端ip地址(可以穿透代理) 
     * @param request 
     * @return 
     */  
    public static String getClientIpAddr(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.getHeader("HTTP_X_FORWARDED_FOR");    
        }    
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
            ip = request.getHeader("HTTP_X_FORWARDED");    
        }    
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
            ip = request.getHeader("HTTP_X_CLUSTER_CLIENT_IP");    
        }    
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
            ip = request.getHeader("HTTP_CLIENT_IP");    
        }    
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
            ip = request.getHeader("HTTP_FORWARDED_FOR");    
        }    
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
            ip = request.getHeader("HTTP_FORWARDED");    
        }    
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
            ip = request.getHeader("HTTP_VIA");    
        }    
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
            ip = request.getHeader("REMOTE_ADDR");    
        }    
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {    
            ip = request.getRemoteAddr();    
        }    
        return ip;    
    }  
    public static String getIpAddr(HttpServletRequest request) {  
        String ip = request.getHeader("X-Real-IP");  
        if (null != ip && !"".equals(ip.trim())  
                && !"unknown".equalsIgnoreCase(ip)) {  
            return ip;  
        }  
        ip = request.getHeader("X-Forwarded-For");  
        if (null != ip && !"".equals(ip.trim())  
                && !"unknown".equalsIgnoreCase(ip)) {  
            // get first ip from proxy ip  
            int index = ip.indexOf(',');  
            if (index != -1) {  
                return ip.substring(0, index);  
            } else {  
                return ip;  
            }  
        }  
        return request.getRemoteAddr();  
    }  

2,如何判断服务器是否是本机

Java代码   
/*** 
     * 服务器是否是本机 
     * @param request 
     * @return 
     */  
    public static boolean isLocalIp(HttpServletRequest request){  
        String ip=WebServletUtil.getClientIpAddr(request);  
        return ip.equals("127.0.0.1")||ip.equals("localhost")||ip.equals("0:0:0:0:0:0:0:1");  
    }  

3,应用:

Java代码   
/*** 
     * favicon.ico  
     * @throws IOException  
     */  
    @RequestMapping(value = "/favicon.ico")  
    public ResponseEntity<byte[]> faviconIco(HttpServletRequest request) throws IOException {  
        HttpHeaders headers = new HttpHeaders();  
        headers.setContentType(MediaType.IMAGE_PNG);  
        String faviconIcoName="sms-4.ico";  
        headers.set(Constant2.CONTENT_DISPOSITION,WebServletUtil.getContentDisposition(true, faviconIcoName));  
        ///home/whuang/software/apache-tomcat-7.0.53/webapps/ROOT/  
        String webappPath=null;  
        if(WebServletUtil.isLocalIp(request)){//服务器在本机(访问ip为127或localhost)  
            webappPath=WebServletUtil.getRealPath(request);  
        }else{  
            webappPath=DictionaryParam.get(Constant2.DICTIONARY_GROUP_GLOBAL_SETTING, "WEB-INF_LOC");  
        }  
        return new ResponseEntity<byte[]>(FileUtils.getBytes4File(  
                webappPath  
                +"WEB-INF/static/img/"+faviconIcoName),  
                                          headers, HttpStatus.CREATED);  
  
    }  

4,如何获取服务器部署的本地路径

Java代码   
public static String getRealPath(HttpServletRequest request) {  
        return getRealPath(request,  "\\");  
    }  
    /** 
     * 获取相对地址的绝对地址 
     *  
     * @param request 
     * @param relativePath 
     * @return 
     */  
    public static String getRealPath(HttpServletRequest request, String relativePath) {  
        return request.getSession().getServletContext().getRealPath(relativePath);  
    }
