How to get client IP in webflux?

Question

I used to call HttpServletRequest.getRemoteAddr() to get client ip.

I'm wondering how can I get it via ServerWebExchange.

My best guess is:

  serverWebExchange.getRequest().getRemoteAddress().getAddress().getHostAddress();

Is it correct?

Answer 1

you can use org.springframework.http.server.reactive.ServerHttpRequest,

String remoteAddress = serverHttpRequest.getRemoteAddress().getAddress().getHostAddress();

as it sad in doc: .reactive.ServerHttpRequest represents a reactive server-side HTTP request.
