我正在尝试从我的hotamil帐户中获取未读的邮件号码。我使用但遇到问题，它总是向我返回收件箱中所有现有的电子邮件号码。在这里，我分享我的代码：
public class testEmail {
public static void check(String host, String storeType, String user,
String password)
{
try {
//create properties field
Properties properties = new Properties();
properties.put("mail.pop3.host", host);
properties.put("mail.pop3.port", "995");
properties.put("mail.pop3.starttls.enable", "true");
// properties.put("mail.imap.ssl.enable", "true");
Session emailSession = Session.getInstance(properties, null);
emailSession.setDebug(false);
//create the POP3 store object and connect with the pop server
Store store = emailSession.getStore("pop3s");
store.connect(host, user, password);
//create the folder object and open it
Folder emailFolder = store.getFolder("INBOX");
emailFolder.open(Folder.READ_ONLY);
//for count the unread email
FlagTerm ft = new FlagTerm(new Flags(Flags.Flag.SEEN), false);
Message messages[] = emailFolder.search(ft);
System.out.println("No. of Unread Messages : " + messages.length);
emailFolder.close(false);
store.close();
} catch (NoSuchProviderException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
String host = "pop-mail.outlook.com";// change accordingly
String mailStoreType = "pop3";
String username = "[email protected]";// change accordingly
String password = "abc";// change accordingly
check(host, mailStoreType, username, password);
}
}
如果我使用
FlagTerm(new Flags(Flags.Flag.SEEN), true);，则返回0。这是关于代码或Hotmail帐户的问题。提前致谢。 最佳答案
Flags.Flag.SEEN在POP3中无法正常工作，因此将其更改为IMAP。如果mail.imap.port = 993不起作用，则还有另一件事，请使用25。答案是关于hotmail。
