Definir uma configuração do Ciclo de Vida do S3 em um bucket

Use o AWS SDK for Java para gerenciar a configuração do S3 Lifecycle de um bucket. Para obter mais informações sobre o gerenciamento da configuração do ciclo de vida do S3, consulte Gerenciar o ciclo de vida dos objetos.

O exemplo a seguir mostra como usar o AWS SDK for Java para adicionar, atualizar e excluir a configuração do ciclo de vida de um bucket. O exemplo faz o seguinte:
