You need to upgrade Spring Boot as well. You are using 2.3.0 and ApplicationContextFactory was added in 2.4, but 2.4.x is no longer supported.

You should upgrade to Spring Boot 2.5.12 or 2.6.6.

I guess it can be caused by the fact that TokenCredentialSerializer is implemented only in Beam 2.33.0. Could you upgrade your Beam dependencies to, at least, Beam 2.33.0 and see if it will solve a problem?

How to correctly create a zip file that can be uploaded to AWS lambda using Eclipse?

How do I create a zip file from an existing Java project that can be uploaded to an AWS Lambda function??

I can't find any clear steps on how to do this. I want to export my Eclipse project as a zip file and then upload it to AWS Lambda. Currently, I use the AWS Toolkit in Eclipse to upload the project, but now I want to do it manually using a zip file.

What are the steps?

This is how I tried to do it. This is where I export the project as a zip:

You can create a Maven project in Eclipse and then Export that as a JAR file that you can upload to the AWS Management Console. Its very easy to do so. To learn how to do this use case, see this AWS tutorial. It uses IntelliJ (just switch that for Eclipse), and follow the rest of the doc.

The example use case for this Lambda function is to detect personal protective equipment (PPE) in images located in an Amazon Simple Storage Service (Amazon S3) bucket. It steps you through all steps including deploying the Lambda function.

Creating an AWS Lambda function that detects images with Personal Protective Equipment

You will never encounter issues that you are seeing in this tool when building and deploying via the Console.

Update This Lambda function works -- just tested it. Here are the results in the Lambda Console.

Data that is placed in the DynamoDB table:

Your error is saying it cannot find the cred provider. When using Lambda, you do not need to set creds in your Java code. The permissions are set in the IAM role. You need to set the policy for the IAM role so it can invoke the services. SO in this example use case, we set policies for lambda-support.

Another Update

From Eclipse, I build a project using your code (I think this PPE is pretty advanced - so we will make a new one named Getting Started with Lambda). It worked well:

Looks like you are trying to use AWS Step Functions using the AWS SDK for Java V2. To get this use working, you can follow this AWS end to end example that walks you through this use case and you will create the following workflow using AWS Step Functions.

Follow this document:

Create AWS serverless workflows by using the AWS SDK for Java

It uses Maven - but shows you the required dependencies (Once you get it working with Maven, then port the dependencies to gradle).

Multiple Functions using Functional Bean Definition in Spring Cloud for AWS Lambda

Asked 2021-Aug-24 at 07:07

I am trying to create a Spring Cloud Function application which will have multiple functions defined in it. I need to use the Functional Bean definition approach for reduced cold start time. The jar will be deployed in AWS Lambda.

The code works in local environment and I am able to curl for all the functions defined. However when deployed in Lambda , the function is not getting located by AWS.

The code runs and is working as expected on Lambda ,if there is only 1 function defined.

I will mention below the things that I have tried.

Followed the Spring Doc to create the project
This works fine in local and also runs in Lambda with Handler org.springframework.cloud.function.adapter.aws.SpringBootStreamHandler::handleRequest as per the comment by Thannasi on mydeveloperplanet blog post
