[REQ] [JAVA] [SPRING] add option to pass authorization token in a method parameter instead of interceptor

Problem

My service is written in Java Spring and I want to use open feign for rest clients. My service performs simultaneously multiple actions, each on behalf of a different principal. As of now an interceptor the only option to authorize requests, and it is cumbersome to use interceptor in my service, as the interceptor have no easy way of knowing what principal to use.

Solution

I would like to pass authorization in a method parameter instead of using interceptor. E.g.

    String somethingGet(@RequestHeader(value = "Authorization") String auth);

No file or test is named. Start by tracing Java Spring client generation and the current authorization interceptor handling; determine where method parameters are represented in the generated client. Done means the generated method can accept an Authorization value per call instead of relying only on the interceptor, with coverage for simultaneous principals.
