Microsoft Graph-如何在Java中构造findMeetingTimes请求？

我正在尝试在我的应用程序中实现findMeetingTimes请求。问题是，Microsoft文档中的确切代码不起作用（）。在这里，我们将meetingDuration作为字符串传递，但所需的类型是javax.xml.datatype.Duration，这令人困惑，因为它是抽象类，显然与Microsoft提供的文档不匹配。正确的实现应该是什么样子

  IGraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider( authProvider ).buildClient();

LinkedList<Option> requestOptions = new LinkedList<Option>();
requestOptions.add(new HeaderOption("Prefer", "outlook.timezone=\"Pacific Standard Time\""));

LinkedList<AttendeeBase> attendeesList = new LinkedList<AttendeeBase>();
AttendeeBase attendees = new AttendeeBase();
attendees.type = AttendeeType.REQUIRED;
EmailAddress emailAddress = new EmailAddress();
emailAddress.name = "Alex Wilbur";
emailAddress.address = "alexw@contoso.onmicrosoft.com";
attendees.emailAddress = emailAddress;

attendeesList.add(attendees);

LocationConstraint locationConstraint = new LocationConstraint();
locationConstraint.isRequired = "false";
locationConstraint.suggestLocation = "false";
LinkedList<LocationConstraintItem> locationsList = new LinkedList<LocationConstraintItem>();
LocationConstraintItem locations = new LocationConstraintItem();
locations.resolveAvailability = "false";
locations.displayName = "Conf room Hood";
locationsList.add(locations);
locationConstraint.locations = locationsList;

TimeConstraint timeConstraint = new TimeConstraint();
timeConstraint.activityDomain = ActivityDomain.WORK;
LinkedList<TimeSlot> timeSlotsList = new LinkedList<TimeSlot>();
TimeSlot timeSlots = new TimeSlot();
DateTimeTimeZone start = new DateTimeTimeZone();
start.dateTime = "2019-04-16T09:00:00";
start.timeZone = "Pacific Standard Time";
timeSlots.start = start;
DateTimeTimeZone end = new DateTimeTimeZone();
end.dateTime = "2019-04-18T17:00:00";
end.timeZone = "Pacific Standard Time";
timeSlots.end = end;
timeSlotsList.add(timeSlots);
timeConstraint.timeSlots = timeSlotsList;

boolean isOrganizerOptional = false;

String meetingDuration = "PT1H";

boolean returnSuggestionReasons = true;

String minimumAttendeePercentage = "100";

graphClient.me()
    .findMeetingTimes(attendeesList,locationConstraint,timeConstraint,meetingDuration,null,isOrganizerOptional,returnSuggestionReasons,minimumAttendeePercentage)
    .buildRequest( requestOptions )
    .post();

IGraphServiceClient-graphClient=GraphServiceClient.builder（）.authenticationProvider（authProvider.buildClient（）；
LinkedList requestOptions=新建LinkedList（）；
添加（新标题选项（“首选”、“outlook.timezone=”太平洋标准时间“）；
LinkedList AttendesList=新建LinkedList（）；
Attendebase Attendes=新Attendebase（）；
Attendes.type=AttendeType.REQUIRED；
EmailAddress EmailAddress=新的EmailAddress（）；
emailAddress.name=“Alex Wilbur”；
emailAddress.address=”alexw@contoso.onmicrosoft.com";
Attendes.emailAddress=电子邮件地址；
AttendesList.add（与会者）；
LocationConstraint LocationConstraint=新的LocationConstraint（）；
locationConstraint.isRequired=“false”；
locationConstraint.suggestLocation=“false”；
LinkedList locationsList=新建LinkedList（）；
LocationConstraintItem位置=新的LocationConstraintItem（）；
locations.resolveavability=“false”；
locations.displayName=“Conf room Hood”；
位置列表添加（位置）；
locationConstraint.locations=位置列表；
TimeConstraint TimeConstraint=新的TimeConstraint（）；
timeConstraint.activityDomain=activityDomain.WORK；
LinkedList timeSlotsList=新建LinkedList（）；
时隙时隙=新时隙（）；
DateTimeZone start=新的DateTimeZone（）；
start.dateTime=“2019-04-16T09:00:00”；
start.timeZone=“太平洋标准时间”；
timeSlots.start=开始；
DateTimeZone end=新的DateTimeZone（）；
end.dateTime=“2019-04-18T17:00:00”；
end.timeZone=“太平洋标准时间”；
timeSlots.end=结束；
timeSlotsList.add（时隙）；
timeConstraint.timeslot=timeSlotsList；
布尔同构=假；
字符串会议持续时间=“PT1H”；
布尔returnSuggestionReasions=true；
字符串minimumattendepercentage=“100”；
graphClient.me（）
.findMeetingTimes（与会者列表、地点限制、时间限制、会议持续时间、空值、同构、返回建议原因、最小与会者百分比）
.buildRequest（请求选项）
.post（）；

我成功地用正确的对象替换了会议持续时间：

 DatatypeFactory factory = DatatypeFactory.newInstance();
        javax.xml.datatype.Duration meetingDuration = factory.newDuration("PT1H");
        
        graphClient.me()
                .findMeetingTimes(attendeesList, null, timeConstraint, meetingDuration, null, true, true, 100.0)
                .buildRequest(requestOptions)
                .post();

问题是，现在如何捕获服务器响应？同样，MS文档中没有一个单词：/
