javamail AuthenticationFailedException:套接字上的EOF [英] javamail AuthenticationFailedException: EOF on socket
本文介绍了javamail AuthenticationFailedException:套接字上的EOF的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我编写了一个程序来使用 JavaMail 检查邮件.代码如下:
I wrote a program to check mails with JavaMail. Here is the code:
private static Folder getFolder(String popHost, int openPort, MailAuthenticator auth) throws MessagingException{
try{
store.close();
}catch(Exception e){
System.out.println("Store konnte nicht geschlossen werden: "+e.getMessage());
}
Properties properties = System.getProperties();
properties.setProperty("mail.store.protocol", "pop3");
properties.setProperty("mail.pop3.host", popHost);
properties.setProperty("mail.pop3.port", String.valueOf(openPort));
properties.setProperty("mail.pop3.auth", "true");
properties.setProperty( "mail.pop3.socketFactory.class",
"javax.net.ssl.SSLSocketFactory" );
Session session = Session.getInstance(properties, auth);
session.setDebug(true);
store = session.getStore( "pop3" );
store.connect();
return store.getFolder( "INBOX" );
它可以在我的 PC 上完美运行,但应该可以在我的 Raspberry Pi 上运行.在 Raspberry store.connect() 上抛出 AuthenticationFailedException:
It works perfectly on my PC, but it should run on my Raspberry Pi. On Raspberry store.connect() throws a AuthenticationFailedException:
DEBUG: setDebug: JavaMail version 1.5.5
DEBUG: getProvider() returning javax.mail.Provider[STORE,pop3,com.sun.mail.pop3.POP3Store,Oracle]

为什么我的 Raspberry 无法连接到主机,而我的 PC 可以?如何在 Raspberry 上修复它?
Why can't my Raspberry connect to host, but my PC can? How can I fix it on Raspberry?
推荐答案
你可以通过将 pop3
转换为 pop3s
来解决这个问题:
You can solve this problem by converting pop3
to pop3s
like this:
properties.setProperty("mail.store.protocol", "pop3s");
properties.setProperty("mail.pop3s.host", popHost);
properties.setProperty("mail.pop3s.port", String.valueOf(openPort));
properties.setProperty("mail.pop3s.auth", "true");
properties.setProperty("mail.pop3s.socketFactory.class",
"javax.net.ssl.SSLSocketFactory" );
properties.setProperty("mail.pop3s.ssl.trust", "*");
store = session.getStore( "pop3s" );
