Gestion de messages Amazon SQS volumineux à l'aide de Java et Amazon S3
Vous pouvez utiliser la bibliothèque client étendue Amazon SQS pour Java
Vous pouvez utiliser la bibliothèque client étendue Amazon SQS pour Java pour effectuer les opérations suivantes :
-
Spécifier si les messages sont toujours stockés dans Amazon S3 ou seulement lorsque leur taille dépasse 256 Ko.
-
Envoyer un message qui fait référence un objet de message unique stocké dans un compartiment S3.
-
Récupérez l'objet du message depuis un compartiment Amazon S3
-
Supprimer l'objet du message d'un compartiment Amazon S3
Prérequis
L'exemple suivant utilise le SDK AWS Java. Pour installer et configurer le SDK, consultez la section Configurer le AWS SDK pour Java dans le Guide AWS SDK for Java du développeur.
Avant d'exécuter l'exemple de code, configurez vos AWS informations d'identification. Pour plus d'informations, consultez la section Configurer les AWS informations d'identification et la région pour le développement dans le guide du AWS SDK for Java développeur.
Le kit SDK pour Java
Note
Vous pouvez utiliser la bibliothèque client étendue Amazon SQS pour Java afin de gérer les messages Amazon SQS à l'aide d'Amazon S3 uniquement avec le AWS SDK for Java. Vous ne pouvez pas le AWS CLI faire avec la console Amazon SQS, l'API HTTP Amazon SQS ou tout autre SDK. AWS
AWS Exemple de SDK pour Java 2.x : utilisation d'Amazon S3 pour gérer des messages Amazon SQS volumineux
L'exemple de AWS SDK pour Java 2.x suivant crée un compartiment Amazon S3 avec un nom aléatoire et ajoute une règle de cycle de vie pour supprimer définitivement les objets après 14 jours. Il crée également une file d'attente nommée MyQueue
et envoie un message aléatoire qui est stocké dans un compartiment S3 et dont la taille est supérieure à 256 Ko pour la file d'attente. Enfin, le code récupère le message, renvoie des informations sur ce dernier et le supprime, ainsi que la file d'attente et le compartiment.

Vous pouvez utiliser Apache Maven pour configurer et créer Amazon SQS Extended Client pour votre projet Java, ou pour créer le SDK lui-même. Spécifiez les modules individuels du SDK que vous utilisez dans votre application.
