本文展示一下如何使用spring mail来发送html邮件。
maven
<!-- email --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId></dependency>
发送图片
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inlineif(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@"},"spring mail发送实例",content,att);}catch (Exception e){e.printStackTrace();}
异常

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);
