Deploy Springframeworka and JPA 2 Quickstart to Cloud Foundry in Minutes

Get started with complex Java Spring Framework and JPA 2 (Hibernate) is slow and time consuming. While Ruby On Rails provide tool to generate project in seconds to quickly start a new Rails application, why not build a Java quick start template that alrady configured all necessary configurations? Getting started with Java web development is tedious and time consuming is not execuse anymore. I will describe how to get started with Java web development in minutes and deploy to Cloud Foundry.

Prerequisite

  • Cloud Foundry Account
  • cf CLI installed
  • maven installed
  • git installed

Clone Project

I created webapp-bootstrap using Spring Framework, JPA 2 (Hibernate) and Twitter Bootstrap template and available on Github. You can clone into your machine to get started:

git clone https://github.com/paukiatwee/webapp-bootstrap.git

Start Local Web Server

The template I created already configured a jetty server to developers can quickly start development straight aways instead of need to setup tomcat/jboss locally. To start the embadded jetty server, just run the followings command:

cd webapp-bootstrap
sh run.sh # or run.bat on Windows

I writed a shell/bat script that start embadded jetty server, underlaying it is executing:

mvn clean compile jetty:run

just to save few keystrokes. :)

Wait the maven download all nessasery jars then you can browse to http://localhost:8080 to view the app. Easy and fast!

Webapp Bootstrap

Packaging War

Before deploy to Cloud Foundry, you will need to package Java web application as a war file. Packaging war file using maven is easy:

mvn clean package

After the command is completed, the war file is generated into target folder. Now you can start deploy to Cloud Foundry!

Deploy to Cloud Foundry

Before you deploy to Cloud Foundry, you must login using cf tool:

cd target
cf login
target: https://api.run.pivotal.io

Email> you@example.com

Password> ***********

Authenticating... OK

After autheticated, you can deploy webapp-bootstrap to Cloud Foundry

cf push webapp-bootstrap

Conclusion

In this post, I deplyo an Java web app to Cloud Foundry in minutes without writing any code. That is how easy to deploy Java application to the cloud if you prepare the template to production and developer friendly! Any question can tweet/follow me @paukiatwee.
