社群網站

使用精靈建立的社群網站結構，會在選取時包含傳訊功能。 請參閱 User Management 設定 社群網站主控台.

程式碼範例：收到的消息通知

Social傳訊功能會擲回操作的事件，例如 send, marking read, marking delete. 您可以擷取這些事件，並對事件中包含的資料採取動作。

以下範例為事件處理常式，其偵聽 message sent 事件，並使用 Day CQ Mail Service.

若要試用伺服器端範例指令碼，您需要開發環境和建立OSGi套件組合的能力：

1. 以管理員身分登入以 [CRXDE|Lite](https://localhost:4502/crx/de).

2. 建立 bundle nodein /apps/engage/install 具有任意名稱，例如：

   • 符號名稱: com.engage.media.social.messaging.MessagingNotification
   • 名稱：快速入門教學課程訊息通知
   • 說明：當使用者收到訊息時傳送電子郵件通知的範例服務
   • 封裝: com.engage.media.social.messaging.notification

3. 導覽至 /apps/engage/install/com.engage.media.social.messaging.MessagingNotification/src/main/java/com/engage/media/social/messaging/notification，然後：

   1. 刪除 Activator.java 類自動建立。
   2. 建立類 MessageEventHandler.java.
   3. 將程式碼複製並貼到下方 MessageEventHandler.java.

4. 按一下 全部儲存.

5. 導覽至 /apps/engage/install/com.engage.media.social.messaging.MessagingNotification/com.engage.media.social.messaging.MessagingNotification.bnd，並依照 MessageEventHandler.java 程式碼。

6. 建立套件組合。

7. 確保 Day CQ Mail Service已配置OSGi服務。

8. 以示範使用者身分登入，並傳送電子郵件給其他使用者。

9. 收件者會收到有關新訊息的電子郵件。
