Actual ClientIP (RemoteAddr)

[barneykim]

As you already know, If you are using a proxy server or the L7 equipment, the ClientIP(RemoteAddr) is the IP address of the Proxy or L7 equipment.
In this case, you must use the x-forwarded-for in the HTTP header.

61 line of StandardHostValveInvokeInterceptor are following:

final String remoteAddr = request.getRemoteAddr();
trace.recordRemoteAddress(remoteAddr);

I want change, as shown below.

final String remoteAddr = getRemoteAddr(request);
...
private String getRemoteAddr(HttpServletRequest request) {
    String remoteAddr = request.getHeader("x-forwarded-for");
    if (StringUtils.isBlank(remoteAddr)) {
        remoteAddr = request.getRemoteAddr();
    } else {
        remoteAddr = remoteAddr.split(",")[0].trim();
    }
   return remoteAddr;
}
