Flex Java Example

A minimalist java/spring-boot example integration using Flex-API tokenization.

Prerequisites

Setup Instructions

  1. Modify ./src/main/resources/application.properties with the credentials created through VISA Developer Portal.
vdp.api-key=_YOUR_APPLICATION_SPECIFIC_API_KEY_
vdp.shared-secret=_YOUR_APPLICATION_SPECIFIC_SHARED_SECRET_
  1. Build and run the application using maven
mvn clean spring-boot:run

This will serve the application from https://localhost:8443.

Tips

  • If you are having issues, checkout the full FLEX documentation.

  • To change the port the application is served on, update server.port=8443 in application.properties, replacing 8443 with your desired port number.

  • If the application throws java.security.InvalidKeyException: Illegal key size you have probably not installed the JCE unlimited policy files.

Browser Support

  • Chrome 37+
  • Firefox 34+
  • Edge 12+
  • Opera 24+

NB: IE11 and Safari support could be achieved through the use of polyfills for promises and Web Crypto API such as webcrypto-shim and promiz. However, these are not included in the examples.
