Azure Functions: Java Samples

This repo contains a number of basic samples of Functions written in Java to get you started.

NOTE The samples provided here are just that, samples. They are not ready to be used straight in production, but are intented to get you started with some of the terminology and structure.

It also contains a few basic unit tests and an integration test to exercise some basic Functions and give you some jumping-off points.

It includes...

Function	Trigger	Input	Output Binding(s)
HttpFunc	HttpTrigger	HttpRequestMessage	-
BlobTriggerOutput	BlobTrigger	byte[] from trigger	Blob
CosmosFunc	CosmosTrigger	POJO from trigger	CosmosOutput
ServiceBusProducerFunc	HttpTrigger	POJO from Http Post	ServiceBusOutput
ServiceBusConsumerFunc	ServiceBusTrigger	POJO from trigger	ServiceBusOutput
ServiceBusTopicProducerFunc	HttpTrigger	POJO from Http Post	ServiceBusTopicOutput
ServiceBusTopicConsumerFunc	ServiceBusTopicTrigger	POJO from trigger	ServiceBusTopicOutput
StorageTableQueue	HttpTrigger	POJO from Http	StorageOutput / TableOutput
EventGridFunc	EventGridTrigger	POJO from event grid trigger	CosmosOutput
HttpKeyVaultFunc	HttpTrigger	-	(gets arbritrary value from Key Vault)
BlobTriggeredOCR	BlobTrigger	byte[] from trigger	JSON OCR data for incoming Blob
TimerQueueMonitorFunc.java	TimerTrigger	-	Logs metrics to AppInsights
PostgresCreateJDBC.java	HttpTrigger	-	Sends a row of data to Postgres via JDBC
