Outlook電子郵件和ICS格式 - 奇怪的行爲

首先，我將設置場景。我正在使用雙週庫創建一個VEvent和一個ICalendar。一切工作正常（下面的代碼）。我可以成功向Google發送日曆邀請，並提供相應的「接受，拒絕，添加到日曆」選項。Outlook電子郵件和ICS格式 - 奇怪的行爲

當我向Outlook發送相同的郵件時，我沒有收到正確的邀請。郵件的格式要求收件人發送邀請 - 不會被邀請，也不會添加到他/她的日曆中。

框架：

的Java - JavaMailSender - 彈簧引導 - 雙週

的代碼運行。問題在於Outlook處理日曆邀請的區別。

這裏是Java代碼...

@Service 
public class CalendarEvent { 

private JavaMailSender javaMailSender; 

@Autowired 
public CalendarEvent(JavaMailSender javaMailSender) { 
    this.javaMailSender = javaMailSender; 
} 

public void createCal() throws MessagingException, ParseException, IOException { 

    ICalendar ical = new ICalendar(); 

    VEvent event = new VEvent(); 

    Attendee attendee = new Attendee("Juniper", "[email protected]"); 
    attendee.setRsvp(true); 
    attendee.setRole(Role.ATTENDEE); 
    attendee.setParticipationStatus(ParticipationStatus.NEEDS_ACTION); 
    attendee.setParticipationLevel(ParticipationLevel.REQUIRED); 

    event.addAttendee(attendee); 

    event.setSummary("hello"); 

    DateTime dt = new DateTime(2016, 12, 28, 12, 0); 
    DateTime et = new DateTime(2016, 12, 28, 13, 30); 
    Date starts = (Date) dt.toDate(); 
    Date ends = (Date) et.toDate(); 

    DateStart thisStart = new DateStart(starts, true); 
    DateEnd dateEnd = new DateEnd(ends, true); 

    event.setDateStart(thisStart); 
    event.setDateEnd(dateEnd); 

    Duration reminder = new Duration.Builder().minutes(15).build(); 
    Trigger trigger = new Trigger(reminder, Related.START); 
    Action action = new Action("DISPLAY"); 
    VAlarm valarm = new VAlarm(action, trigger); 
    event.addAlarm(valarm); 

    Duration duration = new Duration.Builder().hours(1).build(); 
    event.setDuration(duration); 

    event.setUid("555xxx"); 
    event.setOrganizer("[email protected]"); 
    event.setLocation("Small"); 

    ical.addEvent(event); 

    String str = Biweekly.write(ical).go(); 

    MimeMessage message = javaMailSender.createMimeMessage(); 
    message.addHeaderLine("charset=UTF-8"); 
    message.addHeaderLine("component=VEVENT"); 
    message.addHeaderLine("method=REQUEST"); 

    message.setFrom("[email protected]"); 
    message.addRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]")); 
    message.setSubject("You're Invited to a Meeting"); 

    // Create the message part 
    BodyPart messageBodyPart = new MimeBodyPart(); 

    // Fill the message 
    messageBodyPart.setHeader("Content-Class", "urn:content-classes:calendarmessage"); 
    messageBodyPart.setHeader("Content-ID", "calendar_message"); 
    messageBodyPart.setDataHandler(new DataHandler(new ByteArrayDataSource(str, "text/calendar")));// very important 


    Multipart multipart = new MimeMultipart(); 


    multipart.addBodyPart(messageBodyPart); 


    message.setContent(multipart); 

    javaMailSender.send(message); 

}

}

這裏是ICS ...

這裏是打開Outlook電子郵件（注意它是如何構成的信息）...

這裏是開啓Gmail電子郵件...

我發現的文件是有限的，希望有人可以有/遇到/ ecountering相同問題。謝謝閱讀。

是你的展望地址與ics文件中的組織者相同嗎？這可能是一個問題 – adekcz

你是對的，那會造成問題。但是，這不是我所面臨的問題。我回到了創建.ics的手動方式，併發布了下面的代碼。適用於Gmail和Outlook（我會想象其他人）。 – ClickerTweeker

我放棄了雙週圖書館...雖然我覺得解決方案很簡單，我可能會重新討論這個問題。爲了紀錄，雙週刊是一個偉大的圖書館，幫助在Java內部創建VEVENTS和VCALENDARS。

我回過頭來手動製作ics。這種格式功能齊全，適用於Gmail和Outlook。

StringBuffer sb = new StringBuffer(); 

    StringBuffer buffer = sb.append(
      "BEGIN:VCALENDAR\n"

      + "END:VALARM\n" 
      + "END:VEVENT\n" 
      + "END:VCALENDAR"); 

    MimeMessage message = javaMailSender.createMimeMessage(); 
    message.addHeaderLine("charset=UTF-8"); 
    message.addHeaderLine("component=VEVENT"); 
    message.addHeaderLine("method=REQUEST"); 

    message.setFrom(invite.getUserID()); 
    message.addRecipient(Message.RecipientType.TO, new InternetAddress(email)); 
    message.setSubject(invite.getSubject()); 

    BodyPart messageBodyPart = new MimeBodyPart();

    Multipart multipart = new MimeMultipart(); 

    multipart.addBodyPart(messageBodyPart); 

    message.setContent(multipart); 

    javaMailSender.send(message);

我有同樣的問題。添加ical.setMethod("REQUEST");爲我解決了它。
