Como capturar redis.serializer.SerializationException

Você pode lidar com exceções com Spring AOP, @Aspect

    public class ErrorInterceptor{
    @AfterThrowing(pointcut = "execution(* your.package..* (..))", throwing = "ex")
    public void errorInterceptorForSerializationException(SerializationException ex) {
        // DO SOMETHING HERE WITH EX
        logger.error( ex.getCause().getMessage());
    }
 @AfterThrowing(pointcut = "execution(* your.package..* (..))", throwing = "ex")
    public void errorInterceptorForSerializationFailedException(SerializationFailedException ex) {
        // DO SOMETHING HERE WITH EX
        logger.error( ex.getCause().getMessage());
    }
    }
