  Spring  Greatset of tools for enterprise Java developers  Web, Data, Social, Security, AMQP, Solr, Redis, Mobile, and many many more…  Each one has its own configuration and setup  Some have multiple ways of achieving the same thing  Getting multiple Spring projects to work together can be challenging 2

  Spring Boot Inspired by micro-frameworks  Very opinionated, meaning it provides defaults  Favors convention over configuration  Works as a plugin with your existing build tools (Maven or Gradle)  Easy integration with Spring projects using “starter dependencies”  Has a CLI for prototyping with Groovy 3

  Getting Started WithSpring Boot  http://start.spring.io  Inherit from the Spring Boot parent POM (Maven)  Add the Spring Boot plugin  Create a class with a “public static void main” method public class App { public static void main(String[] args) throws Exception { SpringApplication.run(App.class, args); } } 4

  Cloud Foundry 5
• 7.
  Getting Started WithCloud Foundry  Need a Cloud Foundry instance  Public hosted options: IBM Bluemix and Pivotal Web Services  Primary way of interacting is with a CLI $ cf create-service <- create services for app $ cf push <- deploy app binary to Cloud Foundry $ cf bind-service <- Bind service to app $ cf start <- start app $ cf scale <- scale app 6

  Using Services Services bound to your application are exposed via an environment variable called VCAP_SERVICES {"cleardb":[{ "name":"todos-mysql", "label":"cleardb", "plan":"spark", "credentials":{ "uri":"mysql://user:[email protected]", "username":"user", "password":"pass" } } ] } 7

  Spring Cloud Connectors  Helps with the doing the mundane tasks of accessing your services in the cloud  Services are exposed via an environment variable called VCAP_SERVICES  Parse JSON to access data  Can be extended for your own services  Works with both plain Java apps as well as Spring apps 8

  Cloud Foundry BuildPlugins  All functionality of the CLI in a plugin for Maven and Gradle  Ideal because you can do consistent deployments using a simple command  Great for continuous integration and delivery of Java projects 9
