Helidon MP Implicit gRPC Server Example

This examples shows a simple gRPC application written using Helidon MP. It is implicit because in this example you don't write the main class, instead you rely on the Microprofile gRPC Server main class.

The gRPC services to deploy will be discovered by CDI when the gRPC server starts. The StringService is a POJO service implementation that is annotated with the CDI qualifier Grpc so that it can be discovered.

Two additional services (GreetService and EchoService) that are not normally CDI managed beans are manually added as CDI managed beans in the AdditionalServices class so that they can be discovered.

This example can be run together with the Basic gRPC Client example which provides a microprofile gRPC client that uses the services deployed in this server.

Build

mvn package

Run

mvn exec:java

Then the services can be accessed on the gRPC endpoint localhost:1408
