WebClient should provide CookieStore support [SPR-17616]

[spring-issuemaster]

GanMing opened SPR-17616 and commented

I encountered a problem with cookie management when I migrated the StatefullRestTemplate to WebClient.

StatefullRestTemplate

I expect to be able to provide a method compatible with the implementation of java.net.CookieStore, I found the following information.

CookieStoreImpl

Or Reactor Netty's HttpClient can provide features like CookieStore.

You ask for a java.net.CookieStore, yet the code you link to uses a org.apache.http.client.CookieStore, which are similar but not the same.

At any rate, the WebClient exposes cookies as a Map, which should be similarly convenient. See
defaultCookies and cookies.

Alternatively, it seems that Jetty does support java.net.CookieStore, so you could use that as the underlying library, see here.
