This post is a step by step guide on deploying a Spring Boot application on Cloud Foundry using the spring jar feature introduced in 1.0.0.RC2.
If you read the Cloud Foundry documentation, they would claim that the proper way to deploy Spring Boot Groovy scripts is via:
spring grab *.groovy
Unfortunately, this approach is almost as effective as Sex Panther Cologne.
It fails badly when you try to include other starter packs, such as the websocket starter pack.
Using the jar approach outlined here allows us to overcome the errors that you might encounter in Cloud Foundry otherwise.
