java獲取用戶登錄ip、瀏覽器信息、SessionId

1、獲取用戶登錄ip

//獲取用戶登錄ip;
String loginIp = request.getHeader("X-Forwarded-For");
if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) {
    loginIp = request.getHeader("X-Real-IP");
}
if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) {
    loginIp = request.getHeader("Proxy-Client-IP");
}
if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) {
    loginIp = request.getHeader("WL-Proxy-Client-IP");
}
if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) {
    loginIp = request.getHeader("HTTP_CLIENT_IP");
}
if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) {
    loginIp = request.getRemoteAddr();
}

2、獲取用戶所使用的瀏覽器信息

/**
*獲取瀏覽器信息;
*/
String ua = request.getHeader("User-Agent");
//轉(zhuǎn)成UserAgent對象
UserAgent userAgent = UserAgent.parseUserAgentString(ua); 
Browser browser = userAgent.getBrowser();
String browserInfo=browser.toString();//瀏覽器名

3、獲取用戶SessionId

request.getSession().getId();

獲取用戶登錄的ip地址（考慮多種請求頭的情況）

這段代碼網(wǎng)上找的，傳一個HttpServletRequest request就行，直接用

public class IpUtil {
    /**
     * 獲取登錄用戶IP地址
     *
     * @param request
     * @return
     */
    public static 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();
        }
        if (ip.equals("0:0:0:0:0:0:0:1")) {
            ip = "本地";
        }
        return ip;
    }
}
