The application in this demo is a simple Spring Boot API service. It returns “Hello World!” upon receiving GET requests.
You can get the entire source code project from the Calabash git repository, in this way:
% git clone https://github.com/dc-support-001/calabash-public.git Cloning into 'calabash-public'... remote: Enumerating objects: 53, done. remote: Counting objects: 100% (53/53), done. remote: Compressing objects: 100% (35/35), done. remote: Total 53 (delta 3), reused 50 (delta 3), pack-reused 0 Unpacking objects: 100% (53/53), 61.32 KiB | 1.20 MiB/s, done.
The code is downloaded to the “calabash-public” directory. You can find the “helloworld” project in it:
% cd calabash-public % ls README.md helloworld kafka-app % cd helloworld % ls README.md build.gradle container gradle gradlew gradlew.bat settings.gradle src %
This is a self-contained Gradle project. You may build and run the application on your local machine. The build process creates a uber jar in “build/libs/helloworld-1.0.2.jar.”
