The following snippet is from the blueprint articles template for defining the Lambda function GetArticle. This template file is a simplified version of the SAM (AWS Serverless Application Model) file that is used in a serverless application to define the application resources stack. You can also use a serverless template to create a serverless project by choosing Select a Serverless template file and then importing the template file. If an empty String is provided, it outputs “Hello World”. It simply takes in a String and outputs it with the prefix “Hello”. hello-world – This blueprint project only includes a simple stand alone Lambda function, HelloWorld, which is not triggered by any event and not bound to any resource.The two functions are GetArticle and PutArticle, which manage storing articles to the backend service and retrieving articles to the front end. This blueprint also leverages an Amazon S3 bucket for storing article content and an Amazon DynamoDB table for storing article metadata. It consists of two Lambda functions triggered by API events. article – This is a simple serverless application that helps manage articles.As you can see in the following figure, the Toolkit provides two blueprints for you to start with: article and hello-world. You can also create a new serverless project using the AWS Toolkit for Eclipse in the usual way: Choose File, New, Other, AWS and then choose AWS Serverless Java Project. To create a serverless project, click the Toolbar AWS and choose New AWS Serverless Project…, The following wizard opens. To complete the installation, you need to review and accept the license and restart Eclipse. ![]() The following figure shows where you can choose these three components in the installation wizard. You should install the AWS Toolkit for Eclipse Core, AWS CloudFormation Tool, and AWS Lambda Plugin to use this feature. To install the latest AWS Toolkit for Eclipse, go to this page and follow the instructions at the top right of the page. ![]() In this blog, I provide two examples to show you how to leverage the Eclipse IDE to create and deploy a serverless application quickly. The serverless application (also called a Lambda-based application) is composed of functions triggered by events. I’m glad to announce that the AWS Lambda plugin in the AWS Toolkit for Eclipse now supports serverless application development for Java.
