Spring Cloud Stream Aggregate Application Sample
|
||||
================================================
|
||||
|
||||
This is a basic example of a Spring Cloud Stream aggregate application.
|
||||
This sample follows the chain of source -> processor -> sink.
|
||||
Since the final component is a sink, we can run this aggregate sample without using a middleware, i.e. the entire chain is done in memory using the channels.
|
||||
Alternatively, we can stop the application at a processor and send the outbound to a middleware through a binder.
|
||||
|
||||
## Requirements
|
||||
|
||||
To run this sample, you will need to have installed:
|
||||
|
||||
* Java 8 or Above
|
||||
|
||||
## Code Tour
|
||||
|
||||
* SourceAppConfiguration - Configuration for the source
|
||||
* ProcessorAppConfiguraion - Configuration for the processor
|
||||
* SinkAppConfiguration - Configuration for the sink
|
||||
* SourceApplication - Spring Boot app for the source
|
||||
* ProcessorApplication - Spring Boot app for the processor
|
||||
* SinkApplication - Spring Boot app for the sink
|
||||
* AggregateApplication - The main aggregate application
|
||||
|
||||
## Running the application
|
||||
|
||||
* Go to the application root
|
||||
|
||||
* `./mvnw clean package`
|
||||
|
||||
* `java -jar target/aggregate-application-0.0.1-SNAPSHOT.jar`
|
||||
|
||||
Source application sends a message every second which will initiate the processor and then the sink (all in memory through the aggregate app).
|
||||
You will see output similar to the following printed on the console every second.

||||

||||

Please note that the applications (SampleSource, SampleTransformer and SampleSink) are bundled inside the single application for the demo purpose only.
|
||||
In practice, these applications run on their own.
|
||||
If at all they need to be bundled together, the best practice is to use `AggregateApplicationBuilder`.

Refer the sample `double` for more info on aggregate application.
