本文展示一下如何使用spring mail来发送html邮件。

maven

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

发送图片

public void send(String from, String[] toMails, String subject, String text,
                     Map 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 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 att = new HashMap<>();
        att.put("image",classPathResource);
        String content = "
                            
                                
spring mail发送实例
                                ![](cid:image)

                            
                         ";
        try{
            mailService.send(new String[]{"[email protected]"},"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);
