将EML转换为MSG-Java

我想从EML文件中读取附件。我更喜欢将EML文件转换为MSG文件，这样我就可以重复使用编写的代码，这可能吗？如果没有，是否有从EML文件读取附件的方法

如果没有，是否有从EML文件读取附件的方法

支持读取EML文件（MIME类型

消息/rfc822

）。参见示例

然后提取附件。另请参见。

您可以使用Aspose.Email API实现EML到MSG的转换和从EML提取附件

从EML中提取附件

//Initialize and Load an existing EML file
MailMessage msg = MailMessage.load(dataDir + "EmailWithAttachment.eml", new EmlLoadOptions());

//Initialize AttachmentCollection object with MailMessage Attachments
AttachmentCollection attachments = msg.getAttachments();

//Iterate over the AttachmentCollection
for (int index = 0; index < attachments.size(); index++) {
    //Initialize Attachment object and Get the indexed Attachment reference
    Attachment attachment = (Attachment) attachments.get_Item(index);
    //Display Attachment Name
    System.out.println(attachment.getName());
    //Save Attachment to disk
    attachment.save(dataDir + "attachment_" + attachment.getName());
}

我与Aspose合作，担任开发人员宣传员

// Initialize and Load an existing EML file by specifying the MessageFormat
MailMessage eml = MailMessage.load(dataDir + "test.eml");
//Save the Email message to disk in Unicode format
eml.save(dataDir + "LoadingEMLSavingToMSG_out.msg", SaveOptions.getDefaultMsgUnicode());
