| == Spring Boot Example with gRPC |
| |
| === Introduction |
| |
| This example demonstrates how you can use Camel-gRPC Starter component. The example is composed of a standalone gRPC server and a Camel Spring-boot gRPC route acting as client. |
| |
| === Server |
| |
| You can build the server under the directory hello-camel-grpc-server with: |
| |
| $ mvn clean install |
| |
| and then run the server with |
| |
| $ mvn exec:java |
| |
| You should see the following output: |
| |
| [source,bash] |
| ---- |
| Aug 08, 2017 8:00:00 AM org.apache.camel.examples.grpc.HelloCamelServer start |
| INFO: Server started. I'm listening on 50051 |
| ---- |
| |
| === Run the client |
| |
| You can build the client example under the directory hello-camel-grpc-client with: |
| |
| $ mvn clean install |
| |
| and then run the example with |
| |
| $ mvn spring-boot:run |
| |
| And you should see this output in the console. |
| |
| [source,bash] |
