AWS Lambda : How to call lambda function from simple java class

Question

I have created simple Lambda function and upload this to AWS Lambda.

import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.r         


        

Answer 1

Another way to invoke lambda from java code is to use LambdaInvokerFactory and I found this approach cleaner. You need to do the following:

1. Define interface representing your function and annotate method with @LambdaFunction

2. Create implementation of the above interface using LambdaInvokerFactory

3. Invoke lambda function using just created proxy object (interface implementation)
