【问题描述】:
我编写了一个程序来使用 JavaMail 检查邮件。代码如下:
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,但它应该可以在我的 Raspberry Pi 上运行。在 Raspberry store.connect() 上会抛出 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,但我的 PC 可以?如何在 Raspberry 上修复它?
【问题讨论】:
-
请将
Store store = session.getStore("pop3");更改为Store store = session.getStore("pop3s");,让我知道它是否有效 -
不行:
javax.mail.AuthenticationFailedException: failed to connect at javax.mail.Service.connect(Service.java:403) at javax.mail.Service.connect(Service.java:246) at javax.mail.Service.connect(Service.java:195) at MailInterface.getFolder(MailInterface.java:294) at MailInterface.getFolder(MailInterface.java:253) at MailWatch.checkMailAccount(MailWatch.java:75) at MailWatch.checkMails(MailWatch.java:46) at MailWatch.run(MailWatch.java:25) -
您是否也将所有属性都更改为
pop3s?我的意思是mail.pop3.*应该改为mail.pop3s.* -
有效吗??
-
是的,所有属性中的 pop3s 都有效。谢谢! ssl 握手有新问题,但我通过
properties.setProperty("mail.pop3s.ssl.trust", "*");解决了它
