springBoot集成阿里云企业邮箱

前言

springboot项目，集成阿里云企业邮箱，进行邮件发送，附带文件

代码

public class AliyunMail {

    public static final String ALIDM_SMTP_HOST = "smtp.qiye.aliyun.com";
    public static final String ALIDM_SMTP_PORT = "25";

    /**
     * @param sendAddress 发件人地址
     * @param sendPassword 发件人密码
     * @param subject 标题
     * @param content 内容
     * @param filePath 附件地址
     * @throws Exception
     * @throws AddressException
     */
    public void sendMail(String sendAddress,String sendPassword,String subject,String content,String internetAddress,String filePath) throws AddressException, Exception {
        //设置SSL连接、邮件环境
        Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
        final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
        Properties props = System.getProperties();
        props.setProperty("mail.smtp.host", ALIDM_SMTP_HOST);
        props.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY);
        props.setProperty("mail.smtp.socketFactory.fallback", "false");
        //设置端口
        props.setProperty("mail.smtp.port", ALIDM_SMTP_PORT);
        //启用调试
        props.setProperty("mail.debug", "true");
        props.setProperty("mail.smtp.socketFactory.port", "465");
        props.setProperty("mail.smtp.auth", "true");
        //建立邮件会话
        Session session = Session.getDefaultInstance(props, new Authenticator() {   //身份认证
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                //发件人账号、密码
                return new PasswordAuthentication(sendAddress, sendPassword);
            }
        });
        //建立邮件对象
        MimeMessage message = new MimeMessage(session);
        //设置邮件的发件人、收件人、主题
        //附带发件人名字
        //  message.setFrom(new InternetAddress("from_mail@qq.com", "optional-personal"));
        //发件人账号
        message.setFrom(new InternetAddress(sendAddress));
        //收件人账号
        message.setRecipients(Message.RecipientType.TO, internetAddress);

        //标题
        //邮件标题
        message.setSubject(subject);

        //内容
        Multipart multipart = new MimeMultipart();
        BodyPart contentPart = new MimeBodyPart();
        //邮件内容
        contentPart.setContent(content, "text/html;charset=utf-8");
        multipart.addBodyPart(contentPart);

        //附件部分
        if (StringUtils.isNotBlank(filePath)) {
            BodyPart attachPart = new MimeBodyPart();
            //附件地址
            FileDataSource fileDataSource = new FileDataSource(filePath);
            attachPart.setDataHandler(new DataHandler(fileDataSource));
            attachPart.setFileName(MimeUtility.encodeText(fileDataSource.getName()));
            multipart.addBodyPart(attachPart);
        }

        message.setContent(multipart);

//        //抄送地址
//        if (StringUtils.isNotBlank(CC)) {
//            InternetAddress[] internetAddressCC = new InternetAddress().parse(CC);
//            message.setRecipients(Message.RecipientType.CC, internetAddressCC);
//        }

        //发送邮件
        Transport.send(message);
    }
}

关键点

    public static final String ALIDM_SMTP_HOST = "smtp.qiye.aliyun.com";
    public static final String ALIDM_SMTP_PORT = "25";

这两个是阿里云企业邮箱服务地址和端口，一般不变。
附件部分，需要注意附件大小，这个有发件邮箱设置而来。
