我正在使用iCalender API在JAVA中发送会议请求。目前,它适用于IST时区,但在CST / CDT或任何其他时区部署相同的应用程序时,在生成会议请求时,它在Outlook中显示错误的时间。
E.g。我正在为今天生成Outlook请求,开始时间为上午10点,结束时间为上午11点。发送Outlook请求时,它将分别显示为开始时间和结束时间的上午11:30至下午12:30。
请参阅下面的代码,了解我如何设置请求的日历内容。
private BodyPart buildCalendarPart() throws Exception {
BodyPart calendarPart = new MimeBodyPart();
TimeZone timezone = TimeZone.getDefault();
long offset = timezone.getOffset(Calendar.ZONE_OFFSET);
Calendar startTime = Calendar.getInstance();
startTime.setTime(taskDTO.getStartDate());
startTime.set(Calendar.HOUR_OF_DAY, 0);
startTime.set(Calendar.MINUTE, 0);
startTime.set(Calendar.SECOND, 0);
if(taskDTO.getStartTimeHrs().equals(12)) {
startTime.set(Calendar.HOUR, 0);
} else {
startTime.set(Calendar.HOUR, taskDTO.getStartTimeHrs());
}
startTime.set(Calendar.MINUTE, taskDTO.getStartTimeMins());
startTime.set(Calendar.SECOND, 0);
if(taskDTO.getStartTimeampm().equalsIgnoreCase(ApplicationConstant.AM))
startTime.set(Calendar.AM_PM,Calendar.AM);
else
startTime.set(Calendar.AM_PM,Calendar.PM);
System.out.println("Start Date :"+startTime.getTime().toString());
Calendar endTime = Calendar.getInstance();
endTime.setTime(taskDTO.getDueDate());
endTime.set(Calendar.HOUR_OF_DAY, 0);
endTime.set(Calendar.MINUTE, 0);
endTime.set(Calendar.SECOND, 0);
if(taskDTO.getEndTimeHrs().equals(12)){
endTime.set(Calendar.HOUR, 0);
}else{
endTime.set(Calendar.HOUR, taskDTO.getEndTimeHrs());
}
endTime.set(Calendar.MINUTE, taskDTO.getEndTimeMins());
endTime.set(Calendar.SECOND, 0);
if(taskDTO.getEndTimeampm().equalsIgnoreCase(ApplicationConstant.AM))
endTime.set(Calendar.AM_PM, Calendar.AM);
else
endTime.set(Calendar.AM_PM, Calendar.PM);
Date startDate = startTime.getTime();
Date endDate = endTime.getTime();
iCalendarDateFormat.setTimeZone(timezone);
//check the icalendar spec in order to build a more complicated meeting request
String calendarContent =
"BEGIN:VCALENDAR\n" +
"METHOD:REQUEST\n" +
"PRODID: BCP - Meeting\n" +
"VERSION:2.0\n" +
"BEGIN:VEVENT\n" +

如果您对同一个
有任何意见,请告诉我提前致谢!!!

嗯,这完全取决于您如何格式化日期和时间。您的示例代码未显示您如何定义iCalendarDateFormat变量。我怀疑它类似于“yyyyMMdd'T'HHmmss'Z'”,表示UTC时间的日期(表格#2在http://tools.ietf.org/html/rfc5545#section-3.3.5)。因此,您的上午10点IST将转换为UTC时间的4.5 am,收到后,将转换为接收客户端的当地时间。
如果您真的想说“无论用户/客户在哪里,都应该在上午10点出现此事件”,您应该使用当地时间的日期(http://tools.ietf.org/html/rfc5545#section-3.3.5处的表格#1)。换句话说,您的iCalendarDateFormat不应包含最终的'Z'。
最后,一个简单的拼写错误:您正在发送iMIP请求,但您将calendarPart Content-Type设置为“text / calendar; method = CANCEL”。有些客户可能不喜欢这样。
