Azure web function bootstrap dependency injection java

Question

I'm trying to add dependency injection to an Azure Web Function using Java. There are a good deal of examples to do so in C#. There is also a spring boot project that has got it to work. As far I can tell I should be able to add a bootstrap class with a main method to the local.settings.json file. Mine looks like this.

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "",
    "FUNCTIONS_WORKER_RUNTIME": "java",
    "MAIN_CLASS":"com.example.Startup"
  }
}

That class has a main method but it fails to run when I run the azure functions local runner (mvn azure-functions:run). I want to ensure any time the app is run that the class loads and runs before invoking the web endpoint.

The dependency injection support for Java doesn't exist.

There is an open ticket for this: https://github.com/Azure/azure-functions-java-worker/issues/324
