Code Tour - -This sample is a Spring Boot application that bundles multiple application together to showcase how to configure multiple input/output channels. - -* MultipleIOChannelsApplication - the Spring Boot Main Application -* SampleSource - the app that configures two output channels (output1 and output2). -* SampleSink - the app that configures two input channels (input1 and input2). - -The channels output1 and input1 connect to the same destination (test1) on the broker (Kafka) and the channels output2 and -input2 connect to the same destination (test2) on Kafka. -For demo purpose, the apps `SampleSource` and `SampleSink` are bundled together. -In practice they are separate applications unless bundled together by the `AggregateApplicationBuilder`. - -## Running the application - -The following instructions assume that you are running Kafka as a Docker image. - -* Go to the application root -* `docker-compose up -d` - -* `./mvnw clean package` - -* `java -jar target/multi-io-0.0.1-SNAPSHOT.jar` - -The application will log messages from source and sink. -Source sends a message every second which will be consumed by the sink. -You will see output similar to
