An example of sending metadata on connection setup with RSocket.
In this example the
hello-client sends its "clientId" when setting up a connection to the
hello-service. When the client
requests a hello message from the service it returns the message along with the client's identifier that it set during
the connection setup.
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:
Run the following command to start the
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
In a new terminal, run the following command to send a request for a hello message with the
./gradlew :hello-client:run --args=Bob
If successful, you will see that the client connected and specified its client identifier in the
[reactor-tcp-nio-2] INFO example.hello.service.HelloService - Hello client connected: f538925a-c4be-41d5-93cf-f9250e3a8651
and in the
hello-clientterminal you will see that the client id was sent back with the hello message:
> Task :hello-client:run [main] INFO example.hello.client.HelloClient - Sending request for 'Bob' [main] INFO example.hello.client.HelloClient - Response: Hello, Bob! [clientId: f538925a-c4be-41d5-93cf-f9250e3a8651]
