在交换机上收听新电子邮件
我正尝试使用ews-java API连接到我的收件箱并收听新电子邮件。在交换机上收听新电子邮件
我似乎能够连接蛮好的,我从例子在github这里复制代码:
// Subscribe to push notifications on the Inbox folder, and only listen
// to "new mail" events.
PushSubscription pushSubscription = service.SubscribeToPushNotifications(
new FolderId[] { WellKnownFolderName.Inbox },
new Uri("https://...") /* The endpoint of the listener. */,
5 /* Get a status event every 5 minutes if no new events are available. */,
null /* watermark: null to start a new subscription. */,
EventType.NewMail);
然而,这是Eclipse中的错误:
new FolderId[] { WellKnownFolderName.Inbox }, // <---TYPE MISMATCH - CANNOT CONVERT FRM
WELLKNOWNFOLDERNAME TO FOLDERID
还有
EventType.NewMail); // <---- NEWMAIL CANNOT BE RESOLVED OR IS NOT A FIELD
它很难解决这个问题,因为我无法找到关于这个lib的所有方法的手册 - 而且这个例子不起作用。
完整的代码是:
package com.geekhelp.quickstart;
import javax.swing.event.DocumentEvent.EventType;
import microsoft.exchange.webservices.data.autodiscover.IAutodiscoverRedirectionUrl;
import microsoft.exchange.webservices.data.core.ExchangeService;
import microsoft.exchange.webservices.data.core.enumeration.misc.ExchangeVersion;

public class App {
public static void main(String[] args) {
System.out.println("Running");
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
ExchangeCredentials credentials = new WebCredentials("[email protected]", "test");
service.setCredentials(credentials);
try {
service.autodiscoverUrl("[email protected]");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("Hello World");
EmailMessage message;
try {
message = new EmailMessage(service);
message.getToRecipients().add("[email protected]");
message.setSubject("attachements");
message.setBody(MessageBody.getMessageBodyFromText("Email attachements"));
message.send();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// Subscribe to push notifications on the Inbox folder, and only listen
// to "new mail" events.
PushSubscription pushSubscription = service.SubscribeToPushNotifications(
new FolderId[] { WellKnownFolderName.Inbox }, // <------------ TYPE MISMATCH - CANNOT CONVERT FRM
WELLKNOWNFOLDERNAME TO FOLDERID
new java.net.URI("https://mail.test.com//EWS//Exchange.asmx") /* The endpoint of the listener. */,
5 /* Get a status event every 5 minutes if no new events are available. */,
null /* watermark: null to start a new subscription. */,
EventType.NewMail); // <----------- NEWMAIL CANNOT BE RESOLVED OR IS NOT A FIELD
}
感谢。
UPDATE
谢谢,但我仍然得到一个错误:
FolderId[] folderId = { new FolderId(WellKnownFolderName.Inbox)};
PushSubscription pushSubscription = service.subscribeToPushNotifications(folderId , service.getUrl(), 5, null, EventType.NewMail);
subscribeToPushNotifications的红色下划线和IDE说:
的方法subscribeToPushNotifications(可迭代,URI,INT,字符串,EventType ...)在ExchangeService类型中不适用于参数(FolderId [],URI,int,null,EventType)
Tw东西:
1)要创建FolderId
从WellKnownFolderName
,您必须使用relevant constructor。所以改变: new FolderId[] { WellKnownFolderName.Inbox }
到:
new FolderId[] { new FolderId(WellKnownFolderName.Inbox) }
注:new FolderId[] {..}
只创建一个数组。然后数组中的每个项目必须是FolderId
类型,所以我们使用构造函数new FolderId(...)
并传递WellKnownFolderName
作为参数。
2)要导入的错误EventType
(可能是在IDE的功能AUTOIMPORT故障),
因此改变: import javax.swing.event.DocumentEvent.EventType;
到:
import microsoft.exchange.webservices.data.core.enumeration.notification.EventType;
