Activate Spring profile support for SpringBootLambdaContainerHandler

[adsil2]

I have integrated my Spring boot application into the lambda runtime using this library. How do I support multiple profiles of runtime execution. I know this is possible in the SpringLambdaContainerHandler:

SpringLambdaContainerHandler.getAwsProxyHandler().activateSpringProfiles("dev");

Here is example of my code:

public class LambdaHandler implements RequestHandler<AwsProxyRequest, AwsProxyResponse> {

    private SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
    private Logger log = LoggerFactory.getLogger(LambdaHandler.class);

    public LambdaHandler() throws Exception {

        long milis = System.currentTimeMillis();
        handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(TestApplication.class);
        log.info("Loading time: " + (System.currentTimeMillis() - milis));
    }

    public AwsProxyResponse handleRequest(AwsProxyRequest awsProxyRequest, Context context) {
        log.info("*************** Handling REQUEST -LAMBDA  *********** received: " + awsProxyRequest.toString());
        log.info("*************** Handling REQUEST -LAMBDA  ***********  context: " + context.toString());
        log.info("*************** Handling REQUEST -LAMBDA  *********** endpoint path: " + awsProxyRequest.getPath());
        log.info("*************** Handling REQUEST -LAMBDA  *********** endpoint method : " + awsProxyRequest.getHttpMethod());
        log.info("*************** Handling REQUEST -LAMBDA  *********** endpoint paremeters: " + awsProxyRequest.getQueryStringParameters());
        log.info("*************** Handling REQUEST -LAMBDA  *********** endpoint resource: " + awsProxyRequest.getResource());
        return handler.proxy(awsProxyRequest, context);
    }


}

I'll look into this. Let me flag it as an enhancement request.

Thank you very much!

Quick question. Have you tried setting the active profile directly in your application?

@Autowired
private ConfigurableEnvironment env;
...
env.setActiveProfiles("someProfile");

[adsil2]

No . Let me try and get back to you shortly.

Hey @adsil2, any update on this?

[adsil2]

Hi @sapessi -- Is it possible to autowire this in my LambdaHandler class? (see above) I can get stage from APIGateway stage variable and then call the above?

[sapessi]

Not sure Spring will autowire something from the handler class. I have not tried. You can get the stage value any time by extracting the api gateway context from the request - take a look at the sample here: https://github.com/awslabs/aws-serverless-java-container/wiki#security-and-api-gateway-context

[adsil2]

Getting the stage value in the LambdaHandler from API gateway stage is not the issue here. It is how to get it passed to the the wrapped springboot application. The goal is for the application to pick it's configuration from the appropriate "application-.properties" .

Once I get the stage in the LambdaHandler how do I get it to a ConfigurableEnvironment instance, since it cannot be autowired -i.e. it is running outside Spring. Do you see what I mean?

Hey @adsil2, in the latest commit I've added an activateSpringProfiles(String... profiles) method to the SpringBootLambdaContainerHandler object. When you call this method, the system will flag the application for re-initialization and set the spring.profiles.active property accordingly.
