使用javamail发送邮件不起作用

Question

我正在尝试使用我的Gmail地址发送和发送电子邮件。 我将debug设置为true，这就是我得到的。

DEBUG: JavaMail version 1.4.1
DEBUG: not loading file: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/javamail.providers

DEBUG SMTP: useEhlo true, useAuth true
DEBUG SMTP: trying to connect to host "smtp.gmail.com", port 465, isSSL true

然后我什么也不做，没有错误/警告/ ....

我正在使用以下设置：

mail.smtp.auth=true
mail.debug=true
mail.smtp.host=smtp.gmail.com
mail.smtp.user=MyOwnUserName@gmail.com
mail.smtp.password=MyOwnPassword
mail.transport.protocol=smtp
mail.smtp.port=465
mail.disable=false
mail.verbose=true
mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

我尝试了以下示例：

1. http://adfblogs.blogspot.be/2012/01/sending-e-mail-from-adf-application.html
2. 使用Java发送电子邮件

都是一样的问题。 而且我100％确定我的密码和emailadress是正确的。

编辑：我的代码（与第一个链接相同）nitialContext ic = new InitialContext（）; 会话会话=（Session）ic.lookup（“ mail / SugarCRMMailSession”）;

        Properties props = session.getProperties();

        String  to = emailID;

        String mailhost = props.getProperty("mail.smtp.host");
        String user = props.getProperty("mail.smtp.user");
        String password = props.getProperty("mail.smtp.password");
        String protocol = props.getProperty("mail.transport.protocol");

        String authorization = props.getProperty("mail.smtp.auth");
        String mailDisabled = props.getProperty("mail.disable");
        String verboseProp = props.getProperty("mail.verbose");
        String debugProp = props.getProperty("mail.debug");

        boolean sentDisabled = false;
        if(mailDisabled.equals("true"))
            sentDisabled = true;

        if(!sentDisabled){

            boolean auth = false;
            if(authorization.equals("true"))
                auth = true;

            boolean verbose = false;
            if(verboseProp.equals("true"))
                verbose = true;

            String mailer = "smtpsend";

            if(debugProp.equals("true"))
                session.setDebug(true);
            else
                session.setDebug(false);

            Message msg = new MimeMessage(session);
            msg.setFrom();      
            msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to, false));
            msg.setSubject(subject);
            msg.setContent(text, "text/html;charset=UTF-8");      
            msg.setHeader("X-Mailer", mailer);
            msg.setSentDate(new Date());

            SMTPTransport t = (SMTPTransport)session.getTransport(protocol);

            try {
                t.connect(mailhost, user, password);
                t.sendMessage(msg, msg.getAllRecipients());
            } finally {
                    t.close();
            }

             System.out.println("\nMail was sent successfully.");
        }else{
             System.out.println("Mail Sending is disabled.");
        }

在这里，这是解决您问题的完美解决方案，请在此处下载Mail api jar表格

Gmail的api邮件提供商

然后转到Windows->首选项-> Java->已安装的JRES->

以及您正在使用的JRE，只需选择它并进行编辑，然后将该外部jar添加到该JRE中，然后单击okey，则Compiler将能够加载该jar文件。 因此错误将得到解决。

试试吧。
