spring-grpc-service

This is an example gRPC service using Java 21 and the Spring Boot framework.

The service's protobuf interface is compiled to both Java and C++ by Gradle.

Setup

Use SDKMAN to install Java 21 and Gradle 8.4:

sdk install java 21-graalce && sdk default java 21-graalce
sdk install gradle 8.4 && sdk default gradle 8.4

Build and run:

./gradlew build
java -jar build/libs/spring-grpc-service-0.0.1-SNAPSHOT.jar

Run without building:

./gradlew bootRun

You can now send gRPC requests to localhost:8000:

$ grpcurl -plaintext -d '{"name": "Alice"}' localhost:8000 io.github.willroberts.springgrpcservice.HelloService/hello
{
  "resp": "Hello, Alice"
}
