SpringBoot整合Mail

Spring中默认有starter实现类Mail

依赖

    org.springframework.boot
    spring-boot-starter-mail

简单邮件

public void sendSimpleMail(){
    try{
        SimpleMaileMessage simpleMailMessage = new SimpleMailMessage();
        simpleMailMessage .setFrom("[email protected]");
        simpleMailMessage .setTo("[email protected]");
        simpleMailMessage.setSubject("主题");
        simpleMailMessage.setText("内容");
        javaMailSender.send(simpleMailMessage);//发送
    }catch(Exception e){
        logger.error("发送失败",e.getMessage());
    }
}

自定义发件人名称

String nick = "";
            try {
                nick = javax.mail.internet.MimeUtility.encodeText("张三");
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            }
            // 设置发件人
            mimeMsg.setFrom(new InternetAddress("[email protected]", nick));

html格式邮件

public void sendHTMLMail(MailBean mailBean) {
        MimeMessage mimeMailMessage = null;
        try {
            mimeMailMessage = javaMailSender.createMimeMessage();
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMailMessage, true);
            mimeMessageHelper.setFrom(MAIL_SENDER);
            mimeMessageHelper.setTo(mailBean.getRecipient());
            mimeMessageHelper.setSubject(mailBean.getSubject());
            mimeMessageHelper.setText("
hello
", true);
            javaMailSender.send(mimeMailMessage);
        } catch (Exception e) {
            logger.error("邮件发送失败", e.getMessage());
        }
    }

带附件格式的邮件

 public void sendAttachmentMail(MailBean mailBean) {
        MimeMessage mimeMailMessage = null;
        try {
            mimeMailMessage = javaMailSender.createMimeMessage();
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMailMessage, true);
            mimeMessageHelper.setFrom(MAIL_SENDER);
            mimeMessageHelper.setTo(mailBean.getRecipient());
            mimeMessageHelper.setSubject(mailBean.getSubject());
            mimeMessageHelper.setText(mailBean.getContent());
            //文件路径  spring的FileSystemResource,使用绝对路径访问文件资源
            FileSystemResource file = new FileSystemResource(new File("src/main/resources/static/image/mail.png"));
            mimeMessageHelper.addAttachment("mail.png", file);

            javaMailSender.send(mimeMailMessage);
        } catch (Exception e) {
            logger.error("邮件发送失败", e.getMessage());
        }
    }

发送带静态资源的邮件

    public void sendInlineMail(MailBean mailBean) {
        MimeMessage mimeMailMessage = null;
        try {
            mimeMailMessage = javaMailSender.createMimeMessage();
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMailMessage, true);
            mimeMessageHelper.setFrom(MAIL_SENDER);
            mimeMessageHelper.setTo(mailBean.getRecipient());
            mimeMessageHelper.setSubject(mailBean.getSubject());
            mimeMessageHelper.setText("带静态资源的邮件内容，这个一张IDEA配置的照片:", true);
            //文件路径
            FileSystemResource file = new FileSystemResource(new File("src/main/resources/static/image/mail.png"));
            mimeMessageHelper.addInline("picture", file);

            javaMailSender.send(mimeMailMessage);
        } catch (Exception e) {
            logger.error("邮件发送失败", e.getMessage());
        }
    }

基于Freemarker的模板邮件

public void sendTemplateMail(MailBean mailBean) {
        MimeMessage mimeMailMessage = null;
        try {
            mimeMailMessage = javaMailSender.createMimeMessage();
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMailMessage, true);
            mimeMessageHelper.setFrom(MAIL_SENDER);
            mimeMessageHelper.setTo(mailBean.getRecipient());
            mimeMessageHelper.setSubject(mailBean.getSubject());

            Map model = new HashMap();
            model.put("content", mailBean.getContent());
            model.put("title", "标题Mail中使用了FreeMarker");
            Template template = configuration.getTemplate("mail.ftl");
            String text = FreeMarkerTemplateUtils.processTemplateIntoString(template, model);
            mimeMessageHelper.setText(text, true);

            javaMailSender.send(mimeMailMessage);
        } catch (Exception e) {
            logger.error("邮件发送失败", e.getMessage());
        }

    }

动态添加邮箱配置信息

和之前使用接口javaMailSender不同，这次使用的是接口的实现类。
使用JavaMailSenderImpl

public void sendSimpleMail() throws Exception {
    JavaMailSenderImpl mailSender = new JavaMailSenderImpl();//直接生产一个实例
    String users[] = {"[email protected]","[email protected]"};
    mailSender.setHost("smtp.126.com");//动态添加配置
    mailSender.setPassword("xxxxx");
    mailSender.setPort(25);
    mailSender.setProtocol("smtp");
    mailSender.setUsername("xxxxx");
    SimpleMailMessage message = new SimpleMailMessage();
    message.setFrom("xxxxxxx");
    message.setTo(users); // 使用数组的形式还可以群发
    message.setSubject("羽毛球比赛");
    message.setText("报名参加羽毛球赛");
    mailSender.send(message);
    }
