A small Java application showing how to use the Featurevisor Java SDK.
Learn more about Featurevisor here.
It fetches a production datafile, creates a Featurevisor instance with customer context, then evaluates a flag, a variation, feature variables, and global variables.
The SDK is published through GitHub Packages. Create ~/.m2/settings.xml with credentials that have the read:packages scope:
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"> <servers> <server> <id>github</id> <username>YOUR_GITHUB_USERNAME</username> <password>YOUR_GITHUB_TOKEN</password> </server> </servers> </settings>
Keep this file outside the repository.
mvn clean compile
mvn exec:java -Dexec.mainClass="com.example.App"The application evaluates commerce_platform, checkout_experience, max_items, payment_methods, serviceEndpoints, and supportContact from this datafile:
https://featurevisor-example-cloudflare.pages.dev/production/featurevisor-sdk-v3.json
Expected output:
Commerce platform enabled: true
Checkout variation: express
Maximum checkout items: 25
Payment methods: [card, wallet]
Service endpoint: https://api.eu.example.com (timeout: 1200 ms, retries: 4)
Support contact: [email protected]
Change the context in App.java to see how Featurevisor selects different rules, variations, and global variable overrides.
The datafile is generated by the Featurevisor Cloudflare example.
