Quickstart Function that response to HTTP request

developing Azure Functions using Java

Your first Java based Lamda

mvn archetype:generate -DarchetypeArtifactId=azure-functions-archetype

(I had to clean my ~/.m2 folder before that or it would return me a super outdated version)

It will already have a Function that responds to web requests with a default response

Try to run it locally

mvn clean package
mvn azure-functions:run

And it will tell you the URL you need to use to test it.

Http Functions:
HttpExample: [GET,POST] http://localhost:7071/api/HttpExample

For me it was http://localhost:7071/api/HttpExample?name=Thorsten

You can import this into Eclipse via Import existing Maven project.

In order to be able to deploy you need to do

mvn install package azure-functions:deploy

If you get this

You need to do

az login
