Give Your Java Apps “The Boot” With Spring Boot And Cloud Foundry
Download as PPTX, PDF•4 likes•1,776 views
Spring Boot allows Java developers to easily create stand-alone, production-grade Spring-based applications that can be deployed to Cloud Foundry. It handles configuration and provides production-ready features out of the box. Developers can use the Spring Boot initializr to set up new projects, then deploy them to Cloud Foundry using the Cloud Foundry CLI or Maven/Gradle plugins to manage the deployment process and services.
![Getting Started With Spring 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);
}
}

![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:pass@mysqldb.com",
"username":"user",
"password":"pass"
}
}
]

- 2. Who Am I? @ryanjbaxter http://ryanjbaxter.com IBMer for 6 years Developer Advocate for IBM Bluemix Likes using Java Not a Spring expert 1
- 3. Spring Great set 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
- 4. 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
- 5. Getting Started With Spring 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
- 7. Getting Started With Cloud 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
- 8. 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
- 9. 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
- 10. Cloud Foundry Build Plugins 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
