【JavaMail】02 HTML邮件 & 附件邮件

创建HTML邮件：

【email.properties】创建邮件信息配置文件：

# 邮箱厂商信息
mail.smtp.host = smtp.qq.com
mail.smtp.port = 587
mail.smtp.auth = true

# 授权信息
mail.smtp.user = zeal4j
mail.smtp.password = frcgbdjqjzptbegg

# 发送者 & 接收者
mail.smtp.sender = zeal4j@qq.com
mail.smtp.recipient = zeal4j@qq.com

测试方法：

    @Test
    public void sendHtmlEmail() throws Exception {
        // 配置信息脱离硬编码，放在配置文件中
        InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("email.properties");
        Properties properties = new Properties();
        properties.load(inputStream);

        // 得到邮件会话实例
        Session emailSession = Session.getInstance(properties);

        emailSession.setDebug(true);
        Transport transport = emailSession.getTransport();
        transport.connect(properties.getProperty("mail.smtp.host"), properties.getProperty("mail.smtp.user"), properties.getProperty("mail.smtp.password"));

        // HTML邮件创建 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
        MimeMessage mimeMessage = new MimeMessage(emailSession);
        mimeMessage.setFrom(properties.getProperty("mail.smtp.sender"));
        mimeMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(properties.getProperty("mail.smtp.recipient")));

        mimeMessage.setSubject("JavaMail邮件发送测试！！！");
        mimeMessage.setSentDate(new Date());

        // 创建多媒体容器对象
        Multipart multipart = new MimeMultipart();
        MimeBodyPart mimeBodyPart = new MimeBodyPart();

        // HTML代码
        final String htmlCode =
                "<!DOCTYPE html>\n" +
                "<html lang=\"en\">\n" +
                "<head>\n" +
                "    <meta charset=\"UTF-8\">\n" +
                "    <title>Title</title>\n" +
                "</head>\n" +
                "<body>\n" +
                "    <h2>Hello Html Email</h2>\n" +
                "\n" +
                "    <p>testing text in here 测试Html邮件</p>\n" +
                "</body>\n" +
                "</html>";

        mimeBodyPart.setContent(htmlCode, "text/html;charset=utf-8");
        multipart.addBodyPart(mimeBodyPart);
        mimeMessage.setContent(multipart);
        // - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

        // 发送邮件
        transport.sendMessage(mimeMessage, mimeMessage.getAllRecipients());

        // 资源释放
        transport.close();
    }

带附件的邮件：

    @Test
    public void sendIncludeAttachmentsEmail() throws Exception {
        // 配置信息脱离硬编码，放在配置文件中
        InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("email.properties");
        Properties properties = new Properties();
        properties.load(inputStream);

        // 得到邮件会话实例
        Session emailSession = Session.getInstance(properties);

        emailSession.setDebug(true);
        Transport transport = emailSession.getTransport();
        transport.connect(properties.getProperty("mail.smtp.host"), properties.getProperty("mail.smtp.user"), properties.getProperty("mail.smtp.password"));

        MimeMessage mimeMessage = new MimeMessage(emailSession);
        mimeMessage.setFrom(properties.getProperty("mail.smtp.sender"));
        mimeMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(properties.getProperty("mail.smtp.recipient")));

        mimeMessage.setSubject("JavaMail带附件邮件发送测试！！！");
        mimeMessage.setSentDate(new Date());

        // 创建多媒体容器对象
        Multipart multipart = new MimeMultipart();
        MimeBodyPart mimeBodyPart = new MimeBodyPart();

        // HTML代码，也可以不输入HTML，普通文本也支持
        final String htmlCode =
                "<!DOCTYPE html>\n" +
                        "<html lang=\"en\">\n" +
                        "<head>\n" +
                        "    <meta charset=\"UTF-8\">\n" +
                        "    <title>Title</title>\n" +
                        "</head>\n" +
                        "<body>\n" +
                        "    <h2>Hello Html Email</h2>\n" +
                        "\n" +
                        "    <p>附件测试</p>\n" +
                        "</body>\n" +
                        "</html>";

        mimeBodyPart.setContent(htmlCode, "text/html;charset=utf-8");
        multipart.addBodyPart(mimeBodyPart);
        mimeMessage.setContent(multipart);
        // 附件创建 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

        // 需要重新的一个BodyPart对象
        MimeBodyPart attachmentBodyPart = new MimeBodyPart();

        // 文件源对象创建
        FileDataSource fileDataSource = new FileDataSource("D:\\picture\\collection\\330624.jpg");
        // 数据处理器
        DataHandler dataHandler = new DataHandler(fileDataSource);
        // 设置附件
        attachmentBodyPart.setDataHandler(dataHandler);
        // 设置附件名称
        attachmentBodyPart.setFileName(dataHandler.getName());
        // 装填附件Part
        multipart.addBodyPart(attachmentBodyPart);
        // 追加类型为混合的
        // multipart.setSubType("mixed");

        // - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

        // 发送邮件
        transport.sendMessage(mimeMessage, mimeMessage.getAllRecipients());

        // 资源释放
        transport.close();
    }

虽然教程中有提到需要设置混合类型，但是编写发现，根本没有提供这样的API，就直接这样测试了，发现也没有问题
