自動注入HttpServletRequest獲取ip地址

1、在web.xml中配置一個listener

<!-- 配置Request的監聽器 -->
	<listener>
		<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
	</listener>

2、在特定類中注入即可

    @Autowired
    private HttpServletRequest request;

3、獲取ip地址

private static final String COMMA = ",";

    public static String getRemortIP(HttpServletRequest request) {
        String ip = null;
        if (request.getHeader(HeaderBuilder.HttpHeaderKey.X_Forwarded_For.getKey()) != null) {
            ip = request.getRemoteAddr();
            System.out.println("This is ips : " + ip);
            if (ip.contains(COMMA)) {
                ip = ip.substring(0, ip.indexOf(COMMA));
                System.out.println("This is ip : " + ip);
                return ip;
            }
        }
        return ip;
    }

private static final String COMMA = ",";

    public static String getRemortIP(HttpServletRequest request) {
        String ip;
        if (request.getHeader(HeaderBuilder.HttpHeaderKey.X_Forwarded_For.getKey()) != null) {
            ip = request.getRemoteAddr();
            String[] test = ip.split(COMMA);
            List<String> list = Arrays.asList(test);
            return list.get(0);
        }
        return null;
    }

    public static void main(String[] args) throws UnknownHostException {
        String ip = "10.232.136.189, 172.16.0.30";
        //用 getLocalHost() 方法創建的InetAddress的對象
        InetAddress address = address = InetAddress.getLocalHost();
        //獲取IP地址
        String hostAddress = address.getHostAddress();

        String[] test = ip.split(COMMA);
        List<String> list = Arrays.asList(test);
        System.out.println(list.get(0));
    }

    public static String hostAddress() {

        //用 getLocalHost() 方法創建的InetAddress的對象
        InetAddress address = null;
        try {
            address = InetAddress.getLocalHost();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
        //獲取IP地址
        String hostAddress = address.getHostAddress();
        return hostAddress;
    }

    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("HTTP_CLIENT_IP");
            }
            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

                }
            }
        }
        return ip;
