This sample code helps get you started with a simple Java web service using AWS Lambda and Amazon API Gateway.
This sample includes:
- README.md - this file
- buildspec.yml - this file is used by AWS CodeBuild to build the web service
- pom.xml - this file is the Maven Project Object Model for the web service
- src/main - this directory contains your Java service source files
- src/test - this directory contains your Java service unit test files
- template.yml - this file contains the AWS Serverless Application Model (AWS SAM) used by AWS CloudFormation to deploy your application to AWS Lambda and Amazon API Gateway.
If you have checked out a local copy of your repository you can start making changes to the sample code. We suggest making a small change to /src/main/java/com/aws/codestar/projecttemplates/controller/HelloWorldController.java first, so you can see how changes pushed to your project's repository are automatically picked up by your project pipeline and deployed to AWS Lambda and Amazon API Gateway. (You can watch the pipeline progress on your AWS CodeStar project dashboard.) Once you've seen how that works, start developing your own code, and have fun!
To run your tests locally, go to the root directory of the sample code and run the
mvn clean compile test command, which AWS CodeBuild also runs through your buildspec.yml file.
To test your new code during the release process, modify the existing tests or add tests to the tests directory. AWS CodeBuild will run the tests during the build stage of your project pipeline. You can find the test results in the AWS CodeBuild console.

AWS recommends you review the security best practices recommended by the framework author of your selected sample application before running it in production. You should also regularly review and apply any available patches or associated security advisories for dependencies used within your application.
