rsocket-compositemetadata-example

An example of sending composite metadata with RSocket.

In this example the hello-client sends a request to receive a hello message along with some tracing metadata to the hello-service. The service responds with a hello message and echoes the metadata back.

Building the Example

Run the following command to build the example:

./gradlew clean build

Running the Example

Follow the steps below to run the example:

  1. Run the following command to start the hello-service:

     ./gradlew :hello-service:run
    

    If the service has started successfully you will see the following in the terminal:

     > Task :hello-service:run
     [main] INFO example.hello.service.HelloService - RSocket server started on port: 7000
    
  2. In a new terminal, run the following command to send a hello request, with tracing metadata, using the hello-client:

     ./gradlew :hello-client:run --args=Bob
    

    If successful, you will see the following in your terminal:

     Sending request for 'Bob' [traceId: '7b34def1040fa567764848d468a6f876', spanId: '9da1e7f0427747b4']
     Response: Hello, Bob! [traceId: '7b34def1040fa567764848d468a6f876', spanId: '9da1e7f0427747b4']
