Ejemplos de buckets de directorio de S3 que se utilizan SDK para Java 2.x
Los siguientes ejemplos de código muestran cómo realizar acciones e implementar situaciones comunes mediante el uso de buckets AWS SDK for Java 2.x de directorio de S3.
Las acciones son extractos de código de programas más grandes y deben ejecutarse en contexto. Mientras las acciones muestran cómo llamar a las distintas funciones de servicio, es posible ver las acciones en contexto en los escenarios relacionados.
Los escenarios son ejemplos de código que muestran cómo llevar a cabo una tarea específica a través de llamadas a varias funciones dentro del servicio o combinado con otros Servicios de AWS.
En cada ejemplo se incluye un enlace al código de origen completo, con instrucciones de configuración y ejecución del código en el contexto.
Introducción
