Java Function

NOTE This repo has been archived and the sample has moved to:
https://github.com/vmware-tanzu/application-accelerator-samples/tree/main/java-function

This repo contains a simple Java Function that can be deployed as a TAP workload.

This function utilizes the buildpacks provided by VMware's open-source Function Buildpacks for Knative project.

Getting Started

To begin editing your function, refer to the tree diagram below of the file to modify:

java-function
└── src/main/java/functions
    └── Handler.java // EDIT THIS FILE
    └── models/

Inside this file, you will find a example main class, scaffolding, and a function that is invoked by default.

If using TAP workloads, and if you change the name of the default package or class, you will need to update workload.yaml to use the correct Java package:

spec:
  build:
    env:
    - name: BP_FUNCTION
      value: functions.Handler # UPDATE TO YOUR PACKAGE NAME

For more information about how the environment variable works, please see the Java buildpack documentation.

To see samples of code deployable as a Function (FaaS) experience, visit the samples folder.

Deploying

Please see DEPLOYING.md on how to build, deploy, and test your newly built function.
