Provide access to attributes from the handshake HTTP session [SPR-10624]

[spring-projects-issues]

Rossen Stoyanchev opened SPR-10624 and commented

WebSocketSession should provide access to attributes from the HTTP session of the initial handshake request. Since WebSocketSession can be used on the client side as well, it should probably be a general mechanism for initialzing a map of attributes from some source before the session starts.

WebSocketSession now has a handshakeAttributes property. By default it is empty but can be populated with anything, including HTTP session attributes, by configuring a HandshakeInterceptor. There is a concrete interceptor that can copies all or a subset of the HTTP session attributes.
