azure-functions-java-library is a Java library typically used in Serverless, Cloud Functions applications. azure-functions-java-library has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

Azure Functions is a solution for easily running small pieces of code, or "functions," in the cloud. You can write just the code you need for the problem at hand, without worrying about a whole application or the infrastructure to run it. Functions can make development even more productive.Pay only for the time your code runs and trust Azure to scale as needed. Azure Functions lets you develop serverless applications on Microsoft Azure. Azure Functions supports triggers, which are ways to start execution of your code, and bindings, which are ways to simplify coding for input and output data. A function should be a stateless method to process input and produce output. Although you are allowed to write instance methods, your function must not depend on any instance fields of the class. You need to make sure all the function methods are public accessible and method with annotation @FunctionName is unique as that defines the entry for the the function. A deployable unit is an uber JAR containing one or more functions (see below), and a JSON file with the list of functions and triggers definitions, deployed to Azure Functions. The JAR can be created in many ways, although we recommend Azure Functions Maven Plugin, as it provides templates to get you started with key scenarios. All the input and output bindings can be defined in function.json (not recommended), or in the Java method by using annotations (recommended). All the types and annotations used in this document are included in the azure-functions-java-library package.

            QUESTION

            Get the message metadata from an Azure Function QueueTrigger using Java
            Asked 2021-Mar-12 at 08:42

            I am writing an Azure Function in Java using the Micronaut framework.

            My function works perfectly fine if I use the @QueueTrigger to annotate a String to receive a message body. However I would also like to process the metadata.

            The documentation makes mention of Metadata (https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-queue-trigger?tabs=java#message-metadata) and "suggests" the CloudQueueMessage class, which doesn't seem to be available in the com.microsoft.azure.funtions:azure-functions-java-library I even tried including the com.azure:azure-storage-queue library on the off chance.
            (As far as I can tell azure-functions-java-library hasn't moved over to the com.azure name space/GAV yet)

            Is it possible to obtain the Storage Queue message metadata using Java and if so, what am I missing?

            Thanks

            It seems that I was missing something, that you can "bind" to properties of the metadata that are held in CloudQueueMessage class.

            So for my use case all I need to do is add the fulling to the function method:

            QUESTION

            Is there a way to get the headers data of events (EventHub) using @EventHubTrigger of Azure Functions in Java?
            Asked 2020-Sep-03 at 18:41

            I have an Azure Function implemented with azure-functions-java-library that receives events from one EventHub and I'm using @EventHubTrigger, the problem is that I need the header data from an event but I don't see any way to get this, I have already read the docs and nothing. The reason I need this is because from the EventHub I'am receiving events with different Avro schemas so I need to distinguish them in order to parse it.

            I'd really appreciate some help.

            Yes, you can retrieve message metadata by adding a @BindingName("Properties") annotation to a method parameter like below for example. Things to note here you can bind to any metadata of an event using binding expression. In this case, it's "Properties". Also, Cardinality should be ONE.

            Maven Plugin for Azure Web Apps "" not working
            Asked 2018-Aug-09 at 15:17

            Created new project using latest Maven Azure Functions Archetype

            ...

            ANSWER

            Answered 2018-Aug-09 at 15:17

            Document you mentioned is for azure web app, while one for functions says only following properties are supported, including resourceGroup/appName/region/pricingTier/appSettings/deploymentType.

            And we can see there's no code implementation about appServicePlanName in function plugin, while it is implemented in web app plugin.

            So I assume for now it's not supported to deploy function app to existing app service plan using maven plugin.

            And workaround is to create new function app on portal first, then deploy functions to this app with mvn plugin.

            Update

            Not supported indeed, see this issue.

            Update2

            This feature has been supported from 1.0.0-beta-3 azure-functions-maven-plugin.
