# Modifiche all'API S3 Event Notifications dalla versione 1 alla versione 2
<a name="migration-s3-event-notification"></a>

Questo argomento descrive in dettaglio le modifiche all'API S3 Event Notifications dalla versione 1.x (v1) alla versione 2 .x (v2) di. AWS SDK per Java

## Modifiche di alto livello
<a name="migration-s3-event-notification-hl"></a>

### Modifiche strutturali
<a name="migration-s3-event-notification-hl-struct"></a>

La V1 utilizza classi interne statiche per i `EventNotificationRecord` tipi e i relativi attributi, mentre la v2 utilizza classi pubbliche separate per `EventNotificationRecord` i tipi.

### Modifiche alla convenzione di denominazione
<a name="migration-s3-event-notification-hl-naming"></a>

*In v1, i nomi delle classi di attributi includono il suffisso *Entity*, mentre v2 omette questo suffisso per una denominazione più semplice: ad esempio, EventData anziché. *eventDataEntity**

## Modifiche nelle dipendenze, nei pacchetti e nei nomi delle classi
<a name="migration-s3-event-notification-deps"></a>

Nella v1, le classi API di notifica degli eventi S3 vengono importate in modo transitivo insieme al modulo S3 (artifactID). `aws-java-sdk-s3` Tuttavia, nella v2, è necessario aggiungere una dipendenza dall'artefatto. `s3-event-notifications`

## Migra la versione della libreria `aws-lambda-java-events`
<a name="migration-s3-events-notification-lambda-lib"></a>

Se utilizzi eventi [aws-lambda-java-events](https://github.com/aws/aws-lambda-java-libs/tree/main/aws-lambda-java-events)di notifica S3 all'interno di una funzione Lambda, ti consigliamo di eseguire l'aggiornamento alla versione 3.x.x più recente. Le versioni recenti eliminano tutte le dipendenze da AWS SDK per Java 1.x dall'API di notifica degli eventi di S3.

Per ulteriori informazioni sulle differenze nella gestione delle notifiche degli eventi S3 tra la `aws-lambda-java-events` libreria e l'SDK for Java 2.x, consulta. [Elabora gli eventi S3 in Lambda con le librerie Java: e AWS SDK for Java 2.x `aws-lambda-java-events`](examples-s3-event-notifications.md#s3-event-notif-processing-options)
