IllegalStateException: Authentication schemeBearer {jwtTokenHere} not supported

[mateusscheper]

Hi!

I'm trying to secure my gRPC server with JWT but I can't make it work. I already set the token generation but I can't make it validate my token since it always gives me "Authentication scheme Bearer {jwtCodeHere} not supported".

If I put a breakpoint inside AuthenticationSchemeService.class at like 24, I can see it's trying to validate my token as Basic instead of Bearer.

Repository with demo: https://github.com/mateusscheper/java-grpc-demo

How to test:

• grpcurl -plaintext -d "{\"email\": \"anyemail@mail.com\", \"password\": \"teste\"}" localhost:9090 grpc.LoginService.login: Works. Returns JWT token;
• grpcurl -plaintext -H "Authorization: Bearer {jwtTokenHere}" -d "{\"name\": \"Mateus\", \"email\": \"anyemail@mail.com\"}" localhost:9090 grpc.UserService.newUser: Gives "IllegalStateException: Authentication schemeBearer {jwtTokenHere} not supported".

What am I doing wrong? Thank you!

Just saw that in GrpcSecurityConfiguration.class, line 59, it says that the bearer token selector will be used if we have this guy: https://mvnrepository.com/artifact/org.springframework.security/spring-security-oauth2-resource-server. After putting it in my pom.xml, everything worked as expected.
