Example Springboot application for CloudBees Feature Management

This application demonstrates how you can integrate CloudBees Feature Management with your Springboot framework application. The application shows how your Springboot application can respond live to changes in feature flag settings - when you update flag values in the CloudBees platform the display will update within moments.

Insert your SDK Key

Every application using CloudBees Feature Management needs to be configured with an SDK Key that connects it to your Flags & configurations in the CloudBees Platform. You can retrieve your SDK Key for a particular Environment by visiting Feature Management -> Installation. Then, replace the placeholder in src/main/resources/application.yaml with your SDK Key:

rox: key: "<INSERT YOUR SDK KEY HERE>"

For example:

rox: key: "9381b2f4-fcf8-4e03-42fe-b6ed15c887a0"

Run the application

Using your favourite package manager:

gradle bootRun

...then visit the URL:

http://localhost:8080/api/demo

Feature flags

The application uses the following feature flags:

• showMessage

A boolean flag that turns the message on or off.

• message

A string flag that sets the message text.

• fontSize

A number flag that sets the font size. The flag has options for 12, 16, or 24 px text size.

• fontColor

A string flag that sets the font color. The flag has options for red, green, or blue text color.

Modifying flag values

Login to the CloudBees platform and vist the Feature Management section. If you have configured your SDK Key correctly you should see the above flags have been created. Change the value of one of these flags then save, ensuring the Configuration status is On. The application's page will automatically update shortly after to reflect the new flag value(s).

For more information on setting flag values, see the CloudBees Feature Management documentation.
