# Perubahan pada API Pemberitahuan Acara S3 dari versi 1 ke versi 2
<a name="migration-s3-event-notification"></a>

Topik ini merinci perubahan dalam S3 Event Notifications API dari versi 1.x (v1) ke versi 2 .x (v2) dari. AWS SDK untuk Java

## Perubahan tingkat tinggi
<a name="migration-s3-event-notification-hl"></a>

### Perubahan struktural
<a name="migration-s3-event-notification-hl-struct"></a>

V1 menggunakan kelas internal statis untuk `EventNotificationRecord` tipe dan atributnya, sedangkan v2 menggunakan kelas publik terpisah untuk `EventNotificationRecord` tipe.

### Perubahan konvensi penamaan
<a name="migration-s3-event-notification-hl-naming"></a>

*Di v1, nama kelas atribut menyertakan akhiran *Entity*, sedangkan v2 menghilangkan akhiran ini untuk penamaan yang lebih sederhana: misalnya, EventData, bukan. *eventDataEntity**

## Perubahan dependensi, paket, dan nama kelas
<a name="migration-s3-event-notification-deps"></a>

Di v1, kelas API Pemberitahuan Acara S3 diimpor secara transitif bersama dengan modul S3 (ArtifactID). `aws-java-sdk-s3` Namun, di v2, Anda perlu menambahkan ketergantungan pada `s3-event-notifications` artefak.

## Migrasi versi `aws-lambda-java-events` pustaka
<a name="migration-s3-events-notification-lambda-lib"></a>

Jika Anda menggunakan [aws-lambda-java-events](https://github.com/aws/aws-lambda-java-libs/tree/main/aws-lambda-java-events)untuk bekerja dengan peristiwa pemberitahuan S3 dalam fungsi Lambda, kami sarankan Anda meningkatkan ke versi 3.xx terbaru. Versi terbaru menghilangkan semua dependensi pada AWS SDK untuk Java 1.x dari API pemberitahuan acara S3.

Untuk informasi selengkapnya tentang perbedaan dalam menangani notifikasi peristiwa S3 antara `aws-lambda-java-events` pustaka dan SDK for Java 2.x, lihat.
