Spring Cloud Stream Source Sample
|
|
=============================
|
|
|
|
In this *Spring Cloud Stream* sample, a timestamp is published on an interval determined by the fixedDelay property.
|
|
|
|
## Requirements
|
|
|
|
To run this sample, you will need to have installed:
|
|
|
|
* Java 8 or Above
|
|
|
|
This example requires Redis to be running on localhost.
|
|
|
|
## Code Tour
|
|
|
|
This sample is a Spring Boot application that uses Spring Cloud Stream to publish timestamp data. The source module has 3 primary components:
|
|
|
|
* SourceApplication - the Spring Boot Main Application
|
|
* TimeSource - the module that will generate the timestamp and post the message to the stream
|
|
* TimeSourceOptionsMetadata - defines the configurations that are available to setup the TimeSource
|
|
* format - how to render the current time, using SimpleDateFormat
|
|
* fixedDelay - time delay between messages
|
|
* initialDelay - delay before the first message
|
|
* timeUnit - the time unit for the fixed and initial delays
|
|
* maxMessages - the maximum messages per poll; -1 for unlimited
|
|
|
|
## Building with Maven
|
|
|
|
Build the sample by executing:
|
|
|
|
source>$ mvn clean package
|
|
|
|
## Running the Sample
|
|
|
|
To start the source module execute the following:
|
|
|
