Change session cookie name and path in Spring Boot WebFlux

Question

I'm creating a reactive Spring Boot project using WebFlux. I need to configure the session cookie name and path.

In a Tomcat based project it is very easy to configure the session cookie using the configuration file:

server.servlet.session.cookie.name = MYSESSIONID
server.servlet.session.cookie.path = /

If I configure these properties in the WebFlux project it doesn't affect the cookie parameters. How to do that?

as you can see in the property it says "servlet" webflux does not use servlets. — Toerktumlare, Feb 10 '20 at 18:53
That's right, this is exactly why I'm asking. What is the equivalent configuration in WebFlux. — rigon, Feb 11 '20 at 01:06
there is none, webflux uses netty, you have to lookup how to do it in netty, i can't answer that — Toerktumlare, Feb 11 '20 at 01:11

If you happen to be using Spring Session you can create your own bean for the WebSessionIdResolver which is what sets the name (and other attributes) of the session cookie.

@Configuration
public class CookieConfig {

    @Bean
    public WebSessionIdResolver webSessionIdResolver() {
        CookieWebSessionIdResolver resolver = new CookieWebSessionIdResolver();
        resolver.setCookieName("MYSESSIONID");
        return resolver;
    }

}

The Spring Session guides cover this in Spring Session - WebFlux with Custom Cookie.

I also needed to add @EnableSpringWebSession and a ReactiveSessionRepository bean – nagy.zsolt.hun Jul 22 '20 at 16:34
