# Alterações na API de Notificações de Eventos do S3 da versão 1 para a versão 2
<a name="migration-s3-event-notification"></a>

Este tópico detalha as alterações na API de Notificações de Eventos do S3 da versão 1.x (v1) para a versão 2 .x (v2) do AWS SDK para Java.

## Alterações de alto nível
<a name="migration-s3-event-notification-hl"></a>

### Alterações estruturais
<a name="migration-s3-event-notification-hl-struct"></a>

A V1 usa classes internas estáticas para tipos `EventNotificationRecord` e seus atributos, enquanto a v2 usa classes públicas separadas para tipos `EventNotificationRecord`.

### Alterações de convenção de nomenclatura
<a name="migration-s3-event-notification-hl-naming"></a>

*Na v1, os nomes das classes de atributos incluem o sufixo *Entity*, enquanto a v2 omite esse sufixo para simplificar a nomenclatura: por exemplo, eventData em vez de. *eventDataEntity**

## Alterações em nomes de classes, dependências e pacotes
<a name="migration-s3-event-notification-deps"></a>

Na v1, as classes da API de Notificações de Eventos do S3 são importadas transitivamente junto com o módulo do S3 (artifactId `aws-java-sdk-s3`). No entanto, na v2, você precisa adicionar uma dependência do artefato `s3-event-notifications`.

## Migrar a versão da biblioteca `aws-lambda-java-events`
<a name="migration-s3-events-notification-lambda-lib"></a>

Se você costuma [aws-lambda-java-events](https://github.com/aws/aws-lambda-java-libs/tree/main/aws-lambda-java-events)trabalhar com eventos de notificação do S3 em uma função Lambda, recomendamos que você atualize para a versão 3.x.x mais recente. As versões recentes eliminam todas as dependências do AWS SDK para Java 1.x da API de notificação de eventos do S3.

Consulte mais informações sobre as diferenças no gerenciamento de Notificações de Eventos do S3 entre a biblioteca `aws-lambda-java-events` e o SDK para Java 2.x em [Processe eventos do S3 no Lambda com bibliotecas Java: e AWS SDK for Java 2.x `aws-lambda-java-events`](examples-s3-event-notifications.md#s3-event-notif-processing-options).
