Establecimiento de una configuración de S3 Lifecycle en un bucket

Puede utilizar AWS SDK for Java para administrar la configuración del ciclo de vida de S3 de un bucket. Para obtener más información acerca de cómo administrar la configuración de S3 Lifecycle, consulte Administración del ciclo de vida de los objetos.

El siguiente ejemplo muestra cómo usar AWS SDK for Java para añadir, actualizar y eliminar una configuración de ciclo de vida de un bucket. En el ejemplo se realiza lo siguiente:
