JODD消息解析失败；<- java.lang.NullPointerException

Question

我使用的是Jodd版本3.9，我想读取一个outlook帐户(Microsoft Exchange)。]

    int port = 993;
    ImapSslServer imapServer = new ImapSslServer("mail.myhost.it", port, "authuser", "authpass");
    imapServer.setProperty("mail.imap.connectiontimeout", "15000");

    ReceiveMailSession session = imapServer.createSession();
    session.open();
    _log.info("total number of inbox emails : " + session.getMessageCount());
    ReceivedEmail[] emails = session.receiveEmailAndMarkSeen(EmailFilter.filter().flag(Flags.Flag.SEEN, false));

但是我在下面这行得到了这个错误：session.receiveEmailAndMarkSeen(...)

jodd.mail.MailException: Message parsing failed; <--- 
java.lang.NullPointerException

这是一个调试：

A8 FETCH 4 (BODYSTRUCTURE)
* 4 FETCH (BODYSTRUCTURE (("text" "plain" ("charset" "us-ascii") NIL NIL "7bit" 1401 35 NIL NIL NIL NIL) "mixed" ("boundary" "----=_Part_1029639_1159929762.1507643405808") NIL NIL))

[ERROR] 11 ott 04:57:31.467 PM [com.afterbit.jobs.EmailJob] (mGxTfT0) EXCEPTION session.receiveEmailAndMarkSeen : jodd.mail.MailException: Message parsing failed; <--- java.lang.NullPointerException

A9 CLOSE
A8 OK FETCH completed.
A9 OK CLOSE completed.

我不明白为什么..。

Answer 1

解决了我希望这能有所帮助..。节省时间(我花了很多天……)javamail和apache CXF之间存在冲突。apache cxf有一个内部文件geronimo-javamail_1.4_spec-1.7.1.jar。所以如果你在你的项目中添加mail.jar (javamail)并使用IMAP协议，它会产生类似上面的错误！
