ECS Spring Cloud Connectors Demo

This is a simple example of using EMC ECS for asset storage. It is an image catalog to which you can upload images and see them on the main page. It is based off of this Cloud Foundry S3 Demo with some modifications to the connectors to support EMC ECS through Orange OpenSource's Spring Cloud S3 Connectors and the jclouds Blobstore client.

To build just use gradle:

$ ./gradlew assemble

Make sure that a database & bucket are created in Cloud Foundry. So long as there named the same as the manifest, CF will take care of binding them to the app. What's really cool, though, is that any matching database or blobstore service will work. So long as it's MySQL compatible or jclouds compatible (like ECS) the Spring Cloud Connector will figure everything out.

Feel free to peruse the code to see how this all works. Here are some places to look:

• Check out the cloud config for the blobstore that's where your S3 client actually get's created.
• The Spring MVC Controller uses jclouds s3 blobstore to manipulate the files
  • In fact, you can change the jclouds blobstore can work with S3, Swift & others if you decide to switch between backends

The rest of the app is pretty much vanilla. Have fun!
