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:

source>$ java -jar target/spring-cloud-stream-sample-source-1.0.0.BUILD-SNAPSHOT-exec.jar
