Securing rest and actuator endpoints using custom token and http session

Question

I have a spring boot app where the API @Controller endpoints are secured using a token that is contained in the http header. The token needs to be extracted from the header and validated against an internal cache to make sure it is valid. If the token is valid then the request can proceed to the controller and if it is not valid then it should return a 401 to the caller.

I also have another requirement to secure some of the actuator end points. When the user tries to use the browser to access the respective actuator endpoint, it will check for a user session if no session exists then the request is redirected to the spring login page. When they login I need to extract the username and password and validate using an external service. If valid a session can be created for the user and they can then use the hawtio endpoint. The session needs to store role based information so that when the user tries to perform JMX operations it will only allow them to perform the appropriate read only / write if they have the requisite role.

Any pointers regarding how you'd try and tackle this would be most welcome. I am unsure whether this is achieved by specifying addFilterBefore or addFilter and I don't understand how having authenticated the user for the actuator I go about creating a session that can be stored in the context and checked later on for subsequent requests.

Thanks
