Cloud foundry java spring boot application timed out in startup

[davecor]

Hi expert! I have a difficult to understand why a java spring boot application doesn't start correctly when I tried to deploy in my Cloud Foundry space. In local works perfectly, but after cf push command I receive in loop this message.

What does it mean? 

How can I solve it?
