发送邮件时出现异常，java

你好。 我正在尝试重写我们的代码，以使用ssl身份验证发送邮件。因为我们的系统管理员添加了后缀代理身份验证。在linux机器上的主机中，有smtp服务器和ip的服务器名。我检查了与telnet的连接

这里是我创建属性和会话的代码

private Properties createProperties() {
    Properties properties = new Properties();
    properties.setProperty("mail.smtp.host", OurSTMPHostServer);
    properties.setProperty("mail.smtp.port", "587"); //SSL Port
    properties.setProperty("mail.smtp.socketFactory.port", "465"); //SSL Port
    properties.setProperty("mail.smtp.socketFactory.class",  "javax.net.ssl.SSLSocketFactory");
    properties.setProperty("mail.smtp.auth", "true");
    properties.setProperty("mail.smtp.user", MAIL_USER);
    properties.setProperty("mail.smtp.password", MAIL_PASSWORD);
    return properties;
}

private Session createSession(Properties properties) {
    Session session =  Session.getInstance(properties,
            new javax.mail.Authenticator() {
                protected PasswordAuthentication
                getPasswordAuthentication() { return new PasswordAuthentication(MAIL_USER, MAIL_PASSWORD); }
            });
    session.setDebug(true);
    return session;
}

下面是创建消息的代码

public MimeMessage createMimeMessage(String mailFromAddress, String mailFromName,
                                     String subject, String mailTo, String message, String messageText, List<File> fileList) throws MessagingException, UnsupportedEncodingException {
    MimeMessage msg = new MimeMessage(createSession(createProperties()));
    msg.setFrom(new InternetAddress(mailFromAddress, mailFromName));
    msg.setSubject(subject);
    msg.setRecipients(Message.RecipientType.TO, mailTo);
    MimeBodyPart wrap = new MimeBodyPart();
    MimeMultipart cover = new MimeMultipart("alternative");
    MimeBodyPart text = new MimeBodyPart();
    text.setHeader("Content-Transfer-Encoding", "base64");
    text.setContent(messageText, "text/plain;charset=UTF-8");
    cover.addBodyPart(text);
    MimeBodyPart html = new MimeBodyPart();
    html.setHeader("Content-Transfer-Encoding", "base64");
    html.setContent(message, "text/html;charset=UTF-8");
    cover.addBodyPart(html);
    wrap.setContent(cover);
    MimeMultipart content = new MimeMultipart("related");
    msg.setContent(content);
    content.addBodyPart(wrap);
    msg.saveChanges();
    return msg;
}

public void sendTextMessage(String mailFromAddress, @Nullable String mailFromName, String subject, String mailTo, String message) {
    MimeMessage msg = null;
    try {
        String messageText = convertService.htmlToText(message);
        msg = createMimeMessage(mailFromAddress, mailFromName, subject, mailTo, message, messageText, Collections.<File>emptyList());
            mailSenderFacade.send(msg);
    }
}

public MimeMessage createmimessage（字符串mailFromAddress，字符串mailFromName，
字符串主题、字符串邮件收件人、字符串消息、字符串消息文本、列表文件列表）引发MessaginException、UnsupportedEncodingException{
MimeMessage msg=新的MimeMessage（createSession（createProperties（））；
msg.setFrom（新的InternetAddress（mailFromAddress，mailFromName））；
msg.setSubject（主题）；
msg.setRecipients（Message.RecipientType.TO，mailTo）；
MimeBodyPart包裹=新的MimeBodyPart（）；
MimemMultipart封面=新的MimemMultipart（“备选”）；
MimeBodyPart文本=新的MimeBodyPart（）；
setHeader（“内容传输编码”、“base64”）；
setContent（messageText，“text/plain；charset=UTF-8”）；
封面。添加正文部分（文本）；
MimeBodyPart html=新的MimeBodyPart（）；
setHeader（“内容传输编码”、“base64”）；
setContent（消息，“text/html；charset=UTF-8”）；
cover.addBodyPart（html）；
包装。设置内容（封面）；
MimeMultipart内容=新的MimeMultipart（“相关”）；
msg.setContent（content）；
内容。添加车身部件（包裹）；
msg.saveChanges（）；
返回味精；
}

这里是发送消息的代码

public MimeMessage createMimeMessage(String mailFromAddress, String mailFromName,
                                     String subject, String mailTo, String message, String messageText, List<File> fileList) throws MessagingException, UnsupportedEncodingException {
    MimeMessage msg = new MimeMessage(createSession(createProperties()));
    msg.setFrom(new InternetAddress(mailFromAddress, mailFromName));
    msg.setSubject(subject);
    msg.setRecipients(Message.RecipientType.TO, mailTo);
    MimeBodyPart wrap = new MimeBodyPart();
    MimeMultipart cover = new MimeMultipart("alternative");
    MimeBodyPart text = new MimeBodyPart();
    text.setHeader("Content-Transfer-Encoding", "base64");
    text.setContent(messageText, "text/plain;charset=UTF-8");
    cover.addBodyPart(text);
    MimeBodyPart html = new MimeBodyPart();
    html.setHeader("Content-Transfer-Encoding", "base64");
    html.setContent(message, "text/html;charset=UTF-8");
    cover.addBodyPart(html);
    wrap.setContent(cover);
    MimeMultipart content = new MimeMultipart("related");
    msg.setContent(content);
    content.addBodyPart(wrap);
    msg.saveChanges();
    return msg;
}

public void sendTextMessage(String mailFromAddress, @Nullable String mailFromName, String subject, String mailTo, String message) {
    MimeMessage msg = null;
    try {
        String messageText = convertService.htmlToText(message);
        msg = createMimeMessage(mailFromAddress, mailFromName, subject, mailTo, message, messageText, Collections.<File>emptyList());
            mailSenderFacade.send(msg);
    }
}

public void sendTextMessage（String mailFromAddress、@null String mailFromName、String subject、String mailTo、String message）{
mimessage msg=null；
试一试{
字符串messageText=convertService.htmlotext（消息）；
msg=createMimeMessage（mailFromAddress、mailFromName、subject、mailTo、message、messageText、Collections.emptyList（））；
mailSenderFacade.send（msg）；
}
}

其中mailSenderFacade是JavaMailSender类，其中字段host=OurSMTPHostServer，port=465 UPD： 这里是错误

共享异常如何？异常的确切含义是什么？它在哪一行抛出？添加的异常是故意和故意使用两个不同的SMPT端口？我不知道这是否是一个问题，但我以前从未见过。相反，我知道的代码对

“mail.smtp.port”

和

“mail.smtp.socketFactory.port”

使用相同的端口。好吧，那么这样做肯定是错误的；-）
