Class LambdaInvokerFactory

java.lang.Object

com.amazonaws.services.lambda.invoke.LambdaInvokerFactory

public final class LambdaInvokerFactory
extends Object

A factory for objects that implement a user-supplied interface by invoking a remote Lambda function.

 public class Request {
     // Standard POJO stuff here modeling the input your Lambda function
     // expects.
 }

 public class Result {
     // More standard POJO stuff here modeling the output your Lambda
     // function produces.
 }

 public interface LambdaFunctions {

     @LambdaFunction
     Result doSomeStuff(Request request);
 }
 LambdaFunctions functions = LambdaInvokerFactory.builder()
                             .lambdaClient(AWSLambdaSyncClientBuilder.standard()
                                  .withCredentials(new ProfileCredentialsProvider("myprofile"))
                                  .build())
                             .build(LambdaFunctions.class);
 Request request = new Request(...);
 Result result = functions.doSomeStuff(request);
