Spring Boot 根据HttpServletRequest获取请求参数，对密码用***表示

    
    log.info("[preHandle][" + request + "]" + "[" + request.getMethod()
      + "]" + request.getRequestURI() + getParameters(request));



private String getParameters(HttpServletRequest request) {
    StringBuffer posted = new StringBuffer();
    Enumeration<?> e = request.getParameterNames();
    if (e != null) {
        posted.append("?");
    }
    while (e.hasMoreElements()) {
        if (posted.length() > 1) {
            posted.append("&");
        }
        String curr = (String) e.nextElement();
        posted.append(curr + "=");
        if (curr.contains("password") 
          || curr.contains("pass")
          || curr.contains("pwd")) {
            posted.append("*****");
        } else {
            posted.append(request.getParameter(curr));
        }
    }
    String ip = request.getHeader("X-FORWARDED-FOR");
    String ipAddr = (ip == null) ? getRemoteAddr(request) : ip;
    if (ipAddr!=null && !ipAddr.equals("")) {
        posted.append("&_psip=" + ipAddr); 
    }
    return posted.toString();
}

// 这个可以自己去实现个，这里很简单
private String getRemoteAddr(HttpServletRequest request) {
    String ipFromHeader = request.getHeader("X-FORWARDED-FOR");
    if (ipFromHeader != null && ipFromHeader.length() > 0) {
        log.debug("ip from proxy - X-FORWARDED-FOR : " + ipFromHeader);
        return ipFromHeader;
    }
    return request.getRemoteAddr();
}
