public void send(String from, String[] toMails, String subject, String text,
                     Map<String,Object> inlines) throws Exception{
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
        helper.setFrom(from);
        helper.setTo(toMails);
        helper.setSubject(subject);
        helper.setText(text, true); //支持html

        // 增加inline
        if(inlines != null){
            for(Map.Entry<String,Object> entry: inlines.entrySet()){
                if(entry.getValue() instanceof ClassPathResource){
                    helper.addInline(entry.getKey(), (Resource) entry.getValue());
                }

            }
        }

        mailSender.send(mimeMessage);
    }

测试

  • 发送实例
		ClassPathResource classPathResource = new ClassPathResource("image_2.png");
		Map<String,Object> att = new HashMap<>();
		att.put("image",classPathResource);
		String content = "<html>
                            <body>
                                <h4>spring mail发送实例</h4>
                                <img src='cid:image'/><br>
                            </body>
                         </html>";
		try{
			mailService.send(new String[]{"xxxxx@163.com"},"spring mail发送实例",content,att);
		}catch (Exception e){
			e.printStackTrace();
		}

错误码554

554 DT:SPM 发送的邮件内容包含了未被许可的信息,或被系统识别为垃圾邮件。请检查是否有用户发送病毒或者垃圾邮件;

被网易邮箱识别为垃圾邮件了,有个歪招,就是把发送邮箱添加到cc里头

        helper.setCc(from);
