BAEL-1085 (#2428)

* Simple Boot REST application and example

* BAEL-509 - Removed extra duplicate ant matcher

* Example and Unit Tests

* documentation

* BAEL-1085 - changes per PR code review and document review - altered integration to unit test - all's good

* BAEL-1085 - Renamed unit tests and added both to pom.xml

* IntelliJ formatter

* REVERT - Had removed a duplicate ant matcher from BAEL-509 - this was the incorrect process - reverting now, article has been corrected, but will issue a seperate PR for this
