Running the Application

mvn spring-boot:run

Open http://localhost:8080 in your browser.

Endpoints

Path	Description
/	Vue.js frontend
/hello	REST endpoint returning a greeting
/cfenv	Cloud Foundry environment info (returns 404 when not on CF)
/actuator/info	Application info (Spring Boot version, Java version)
/actuator/health	Health check endpoint

Frontend Features

The web UI displays:

• Greeting message - Response from /hello endpoint
• Runtime Info - Spring Boot and Java versions from actuator
• Application Info - CF application details (name, ID, instance, space, URIs)
• Bound Services - List of services bound to the application

When not running on Cloud Foundry, the CF-specific sections show placeholder messages.

Cloud Foundry Environment

The application uses java-cfenv to read Cloud Foundry environment variables:

• VCAP_APPLICATION - Application metadata
• VCAP_SERVICES - Bound service credentials

At startup, the CfEnvService logs the CF environment details and makes them available via the /cfenv endpoint.

Logging

Logs are written using Log4j2. The configuration is in src/main/resources/log4j2.xml.
