EWS(Exchange Service)基本使用（Java）

以你之姓@ 2024-04-23 21:13 4阅读 0赞

## EWS(Exchange Service)基本使用（获取个人会议，会议室会议内容，会议室列表，发送会议，修改会议，删除会议） ##

最近公司要求和exchange服务对接，所以稍微研究了一下官方文档，做出以下总结，欢迎大家补充。

先放出exchange官方开发说明文档：https://docs.microsoft.com/zh-cn/exchange/client-developer/exchange-web-services/calendars-and-ews-in-exchange

1.  与exchange web服务器建立连接

// 与exchange web服务器建立连接
    		ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010);
    		ExchangeCredentials credentials = new WebCredentials("you email", "password");
    		service.setCredentials(credentials);
    		// 这个url可能每个公司不一样，大多数是这个
    		service.setUrl(new URI("https://outlook.office365.com/ews/exchange.asmx"));
    		service.setTraceEnabled(true);

1.  获取会议内容

Calendar start = Calendar.getInstance();
    		start.set(2019,10,1);
    		Calendar end = Calendar.getInstance();
    		end.set(2020,2,1);
    		CalendarFolder calendar = CalendarFolder.bind(service, WellKnownFolderName.Calendar, new PropertySet());
    		CalendarView cView = new CalendarView(start.getTime(), end.getTime());
    		// 指定要查看的邮箱
    		cView.setPropertySet(new PropertySet(AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.End));
    		// Retrieve a collection of appointments by using the calendar view.
    		FindItemsResults<Appointment> appointments = calendar.findAppointments(cView);
    
    		for (Appointment a : appointments)
    		{
        
    			// 获取各个会议信息
    		}

1.  获取会议室会议内容(会议室某天各个会议开始时间，结束时间，主题和发件人)

List<AttendeeInfo> attendees = new ArrayList<>();
            attendees.add(new AttendeeInfo("会议室邮箱", MeetingAttendeeType.Room, true));
            GetUserAvailabilityResults results = service.getUserAvailability(attendees,
                    // 设置当天时间
                    new TimeWindow(DateTime.now().plusDays(0).toDate(), DateTime.now().plusDays(1).toDate()),
                    AvailabilityData.FreeBusy);
            List<Map<String, Object>> list = new ArrayList<>();
            for (AttendeeAvailability availability : results.getAttendeesAvailability())
            {
        
                for (CalendarEvent calEvent : availability.getCalendarEvents())
                {
        
                    Map<String, Object> map = new HashMap<>();
                    // 开始时间和结束时间
                    map.put("start", calEvent.getStartTime());
                    map.put("end", calEvent.getEndTime());
                    CalendarEventDetails details = calEvent.getDetails();
                    if(details != null){
        
                        // subject中包含发件人和主题
                        String subject = details.getSubject();
                        if(StringUtils.isNotBlank(subject)){
        
                            // 按空格区分发件人和主题
                            String[] strings = subject.split(" ");
                            map.put("booker", strings[0]);
                            map.put("meetingName", strings[1]);
                        }
                    }
                    list.add(map);
                }
            }

1.  获取会议室列表

try {
        
    			// 这里先获取大的会议室列表，大多数是按区域分的，不如公司有五个办公地点，这里获取的就是各个办公地点的address
    			EmailAddressCollection myRoomLists = service.getRoomLists();
    			List<String> addList = new ArrayList<String>();
    			for (EmailAddress address : myRoomLists) {
        
    				EmailAddress emailAddress = new EmailAddress(address.getAddress());
    				// 根据各个办公地点的address，再获取具体的所有会议室信息
    				// 如获取北京办公地的所有会议室信息
    				Collection<EmailAddress> list = service.getRooms(emailAddress);
    				for (EmailAddress e : list) {
        
    					addList.add(e.getAddress());
    					System.out.println(e.getName());
    					System.out.println(e.getNamespace());
    				}
    			}
    			return addList;
    		} catch (Exception e1) {
        
    			// TODO Auto-generated catch block
    			e1.printStackTrace();
    		}

1.  发送会议

Appointment appointment = null;
    		try {
        
    			appointment = new Appointment(service);
    			appointment.setSubject("会议主题");
    			appointment.setBody(MessageBody.getMessageBodyFromText("会议消息体"));
    			SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    			// 会议时间，如果使用会议室的话，会议时间一定是会议室空闲的时间，否则创建失败
    			appointment.setStart(format.parse("2020-01-06 11:30:00"));
    			appointment.setEnd(format.parse("2020-01-06 14:30:00"));
                
    			appointment.setLocation("会议位置");
    			// 必须参加的员工的账号
    			// 这里如果会议需要用到会议室的话，一定要添加会议室的邮箱
    			appointment.getRequiredAttendees().add("会议室邮箱");
    			appointment.getRequiredAttendees().add("参与人邮箱1");
    			appointment.getRequiredAttendees().add("参与人邮箱2");
    		
    			// 可选参加的员工的账号
    //			appointment.getOptionalAttendees().add("abc@456.com");
    			// 会议提前15分钟提醒
    			appointment.setReminderMinutesBeforeStart(15);
    			appointment.save(SendInvitationsMode.SendToAllAndSaveCopy);
    //			appointment.update(ConflictResolutionMode.AutoResolve);
    			System.out.println(appointment.getId());
    			Item item = Item.bind(service, appointment.getId(), new PropertySet(ItemSchema.Subject));
    			// 这里创建一个item之后，如果要修改会议，一定要保存好这个item.getId(),否则找不到会议，不能修改
    			System.out.println("会议创建成功： " + item.getSubject());
    		} catch (Exception e) {
        
    			e.printStackTrace();
    		}

1.  修改会议

// itemId即创建会议室生成的唯一itemId
    		Appointment appointment = Appointment.bind(service, 
    				ItemId.getItemIdFromString(itemId), new PropertySet());
    		appointment.setSubject("会议主题21");
    		appointment.setBody(MessageBody.getMessageBodyFromText("会议消息体21"));
    		SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    		appointment.setStart(format.parse("2020-01-06 11:30:00"));
    		appointment.setEnd(format.parse("2020-01-06 14:30:00"));
    
    		appointment.setLocation("会议位置");
    		// 必须参加的员工的账号
    		appointment.getRequiredAttendees().add("邮箱");
    		appointment.getRequiredAttendees().add("邮箱");
    		// 可选参加的员工的账号
    //			appointment.getOptionalAttendees().add("abc@456.com");
    		appointment.setReminderMinutesBeforeStart(15);
    		// Send the update request to the Exchange server.
    		appointment.update(ConflictResolutionMode.AlwaysOverwrite, SendInvitationsOrCancellationsMode.SendToAllAndSaveCopy);
    		System.out.println(appointment.getId());
    		Item item = Item.bind(service, appointment.getId(), new PropertySet(ItemSchema.Subject));
    		System.out.println("会议更新成功： " + item.getSubject());

1.  取消会议

Appointment appointment = Appointment.bind(service, 
    				ItemId.getItemIdFromString(itemId), new PropertySet());
    		// Delete the meeting by using the Delete method.
    		// 取消后，之前创建的会议标题前会加上已取消三个字
    		appointment.delete(DeleteMode.MoveToDeletedItems, SendCancellationsMode.SendToAllAndSaveCopy);
