Bootiful gRPC
summary
Shows a working Spring gRPC stack: a proto3 schema with Java code generation, a running gRPC Netty server auto-configured by Spring Boot, and a Spring web client calling the generated stub; uses OpenTelemetry + Grafana for metrics and grpc_health_probe-compatible health checks on localhost, and integrates OAuth2 via Spring Authorization Server so the client obtains a token and the service validates it. Demo builds, runs and authenticates across ports (9090, 8080, 7070).
