springboot-rsocketsetup-example

An example of sending a SETUP payload with RSocket and Spring Boot.

RSocket allows for data to be sent on connection setup. This is handy for one-time connection configuration tasks your application may need.

This example consists of an RSocket service, hello-service, that returns hello messages in the specified language for one-to-many recipients. The language is specified at connection setup time using the RSocket SETUP frame.

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:bootRun
   

2. In a new terminal, run the following command to execute the hello-client and ask for hello messages for Bob, Susan, Mary, and Tom in United States English:

    ./gradlew :hello-client:bootRun --args="en US Bob Susan Mary Tom"
   

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

    : Connecting to hello-service and configuring locale [language: 'en', country: 'US']
    : Requesting '4' hello message(s)...
    : Response: Hello, Bob!
    : Response: Hello, Susan!
    : Response: Hello, Mary!
    : Response: Hello, Tom!
    : Completed!
   

3. Next, run the following command to execute the hello-client for French messages:

    ./gradlew :hello-client:bootRun --args="fr FR Bob Susan Mary Tom"
   

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

    : Connecting to hello-service and configuring locale [language: 'fr', country: 'FR']
    : Requesting '4' hello message(s)...
    : Response: Bonjour, Bob!
    : Response: Bonjour, Susan!
    : Response: Bonjour, Mary!
    : Response: Bonjour, Tom!
    : Completed!
