creating an aws lambda function spring boot

You can use the aws-serverless-java-container library to run a Spring Boot application in AWS Lambda. You can use the library within your Lambda handler to load your Spring Boot application and proxy events to it. In the repository we have included a sample Spring Boot application to get you started.

@Component("generateShortcode")
public class GenerateShortcodeFunction implements Function<String, String> {

	@Autowired
	private LambdaFunctions lambdaFunctions;
	
	@Autowired
	private UrlDAO urlDAO;

	@Override
	public String apply(String url) {
		try {
			new URL(url);
		} catch (MalformedURLException e) {
			throw new InvalidURLFormatException();
		}

		String shortCode = urlDAO.generateShortCode();
		urlDAO.storeUrl(shortCode, url);

		EmailDetails emailDetails = new EmailDetails("marc@mtdevuk.com",
				"marc@mtdevuk.com", "Congratulations, you have created a shortCode for: " + url,
				url, shortCode);
		lambdaFunctions.sendShortcodeGeneratedEmail(emailDetails);
		
		return shortCode;
	}
}
