java web应用获取IP地址信息

public void testIp(HttpServletRequest request) {
    String localAddr = request.getLocalAddr();
    int localPort = request.getLocalPort();
    String localName = request.getLocalName();
    log.info("local= "+localAddr+"----"+localPort+"---"+localName);
    
    String remoteAddr = request.getRemoteAddr();
    String remoteHost = request.getRemoteHost();
    int remotePort = request.getRemotePort();
    log.info("remote= "+remoteAddr+"----"+remoteHost+"---"+remotePort);
    
    String ip = ThreadLocalUtil.getIp();
    String mac = ThreadLocalUtil.getMac();
    log.info("-----threadLocalUtil--ip--"+ip);
    log.info("-----threadLocalUtil--mac--"+mac);
  }
