Enable Spring Boot

This commis enable Spring Boot which ends up breaking the flow action -> render phase of Liferay. How?
After the correct processing of an action phase Liferay render a blank page, looks like that it doesn't know
which page it must render even though the parameter "render" is set to "alternative-view". For some
reason Spring Boot break the process without any exception or clue.
