If I put a lambda authorizer in the api gateway and want to pass a variable to the ebs hosted spring boot APIs, how to do that?
can you discuss about wiremock as well
@@sarikasabnam785 Wiremock is a tool for mocking HTTP services, and it doesn't directly handle DTO (Data Transfer Object) to entity conversions. But for timebeing we will try to discuss
After intoducing globalHandler exception , any place exception happens, Global class will be called from there?
exactly @ControllerAdvice is taking care that is why we should annotate global exception handling class with this annotation, @ControllerAdvice is a specialized version of the @Component annotation that allows you to handle exceptions globally, apply model attributes to multiple controllers, and bind methods for multiple controllers in a single place.
