No replacement for the @LambdaFunction and LambdaInvokerFactory?

Expected Behavior

One of the great API improvements provided by the v1 SDK was the LambdaInvokerFactory, which handled so much of the marshalling when directly invoking a Lambda.

There seems to be no v2 replacement that I can find, and nothing is mentioned in the 1.11 to 2.0 changelog which is surprising for something that completely disappeared.

Current Behavior

There is no corollary to the @LambdaFunction and LambdaInvokerFactory set of API utilities.

Possible Solution

Re-implement those utilities.

Context

The amount of boilerplate significantly increases when attempting to call Lambda. This is especially apparent when writing functional tests, where the actual details of invoking a Lambda are not relevant to actually testing that Lambda.

Your Environment

• AWS Java SDK version used: v2
• JDK version used: Corretto - 11.0.8
• Operating System and version: Ubuntu 20.04

Inizia confrontando le API LambdaInvokerFactory e @LambdaFunction di v1 collegate nell’issue con la documentazione di v2 e docs/LaunchChangelog.md. Conferma le funzionalità mancanti e definisci cosa deve fornire un sostituto per v2; il lavoro è completo quando i chiamanti possono invocare Lambda con un marshalling comparabile e meno boilerplate.
