Operação de Backup e Restauração IMAP
Aspose.Email for Java oferece a capacidade de fazer backup e restaurar mensagens. Para isso, a API fornece os seguintes métodos.
Este artigo demonstra como fazer backup e restaurar mensagens usando o ImapClient classe.
Backup de Mensagens
Para fazer backup de mensagens, use o ImapClient.backup método conforme demonstrado no trecho de código a seguir.
// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
// The path to the File directory.
String dataDir = "data/";
// Create an instance of the ImapClient class
ImapClient imapClient = new ImapClient();
// Specify host, username and password, and set port for your client
imapClient.setHost("imap.gmail.com");
imapClient.setUsername("your.username@gmail.com");
imapClient.setPassword("your.password");
imapClient.setPort(993);
imapClient.setSecurityOptions(SecurityOptions.Auto);
ImapMailboxInfo mailboxInfo = imapClient.getMailboxInfo();
ImapFolderInfo info = imapClient.getFolderInfo(mailboxInfo.getInbox().getName());
ImapFolderInfoCollection infos = new ImapFolderInfoCollection();
infos.addItem(info);
imapClient.backup(infos, dataDir + "\\ImapBackup.pst", com.aspose.email.BackupSettings.to_BackupSettings(BackupOptions.Recursive));
Restaurar Mensagens
Para fazer backup de mensagens, use o ImapClient.restore método conforme demonstrado no trecho de código a seguir.
// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
// The path to the File directory.
String dataDir = "data/";
// Create an instance of the ImapClient class
ImapClient imapClient = new ImapClient();
// Specify host, username and password, and set port for your client
imapClient.setHost("imap.gmail.com");
imapClient.setUsername("your.username@gmail.com");
imapClient.setPassword("your.password");
imapClient.setPort(993);
imapClient.setSecurityOptions(SecurityOptions.Auto);
ImapRestoreSettings settings = new ImapRestoreSettings();
settings.setRecursive(true);
PersonalStorage pst = PersonalStorage.fromFile(dataDir + "\\ImapBackup.pst");
imapClient.restore(pst, settings);
Operação de Backup e Restauração IMAP com MultiConnection
Ao trabalhar com um grande número de mensagens, a operação de backup/restauração pode levar muito tempo. Para isso, a API fornece suporte a múltiplas conexões durante a operação de backup e restauração. Para habilitar o modo MultiConnection, defina ImapClient.UseMultiConnection propriedade para MultiConnectionMode.Enable. Os trechos de código a seguir demonstram a operação de backup e restauração com o modo MultiConnection habilitado.

imapClient.setPort(993);
imapClient.setSecurityOptions(SecurityOptions.Auto);
imapClient.setUseMultiConnection(MultiConnectionMode.Enable);

imapClient.setUseMultiConnection(MultiConnectionMode.Enable);
ImapRestoreSettings settings = new ImapRestoreSettings();
settings.setRecursive(true);
PersonalStorage pst = PersonalStorage.fromFile(dataDir + "\\Outlook.pst");
imapClient.restore(pst, settings);
