Can someone provide a work example for Splunk HEC using Java Spring Boot?

[aa70627]

Can someone assist with providing a working example on how to use and send data to Splunk HTTP Event Collect (HEC) from a java Spring Boot application? Please provide settings and code used for pom.xml, log4j.xml and code example. We reviewed the example from http://dev.splunk.com/view/splunk-logging-java/SP-CAAAE7M and we're not sure if its applicable to Java spring boot since spring boot automatically loads up its own logger.
