Rocket to the Cloud Fast with Roo

Want to build a Spring 3 application FAST and run it on the Cloud? It is incredibly easy to do with Spring Roo and CloudFoundry!

This post on using Postgres on CloudFoundry helped me get started, however I tried using the 1.2.M1 with the CloudFoundry addon, but was unable to install it successfully in either 1.1.5.RELEASE or 1.2.0.M1.

Recently, Spring Roo moved to GitHub

Steps

1. Get a Free CloudFoundry Account
2. Clone the Spring Roo Git Repository
3. Configure GPG/PGP setup
   see /spring-roo/readme.txt
4. Build Spring Roo with Maven
   mvn -U clean install -Dgpg.passphrase=yourpassphrase
5. Link the Roo startup script
   see /spring-roo/readme.txt

Creating a Project

1. Make a directory for your SimpleItem project
   mkdir /SimpleItem
2. Go to the directory
   cd /SimpleItem
3. Create the script file simpleitem.roo in the /SimpleItem directory
   (see the contents below)
4. Start roo-dev
5. Type the command
   script --file simpleitem.roo
6. Go To: http://mysimpleitem.cloudfoundry.com/

The simpleitem.roo script file

development mode --enabled true

NOTE CloudFoundry is Public

Since CloudFoundry is public, you may run into an issue deploying the application with the name above. You should change the --projectName to something unique with your name in it such as yourname-simpleitem.

Gunnar Hillert’s Blog explains this well.

Adding CloudFoundry Plugin to Maven

Thanks to Gunnar Hillert’s post, we can add to our project’s Maven pom.xml file the CloudFoundry Plugin.

<plugins>
  ...
  <plugin>
    <groupId>org.cloudfoundry</groupId>
    <artifactId>cf-maven-plugin</artifactId>
    <version>1.0.0.M1</version>
    <configuration>
      <server>mycloudfoundry-instance</server>
      <target>http://api.cloudfoundry.com</target>
      <url>${project.name}.cloudfoundry.com</url>
      <memory>256</memory>
    </configuration>
  </plugin>
  ...
</plugins>

Add CloudFoundry Credentials

Add credentials to our userhome/.m2/settings.xml

<servers>
  ...
  <server>
    <id>mycloudfoundry-instance</id>
    <username>you@mycompany.com</username>
    <password>n00n3w1llgu3ss</password>
  </server>
  ...
</servers>

To push (deploy) the code to CloudFoundry type mvn cf:push
For more plugin details type mvn cf:help
