本文展示一下如何使用spring mail來發(fā)送html郵件借卧。
maven
<!-- email -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
發(fā)送圖片
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);
}
測試
- 發(fā)送實例
ClassPathResource classPathResource = new ClassPathResource("image_2.png");
Map<String,Object> att = new HashMap<>();
att.put("image",classPathResource);
String content = "<html>
<body>
<h4>spring mail發(fā)送實例</h4>
<br>
</body>
</html>";
try{
mailService.send(new String[]{"xxxxx@163.com"},"spring mail發(fā)送實例",content,att);
}catch (Exception e){
e.printStackTrace();
}
- 異常

錯誤碼554
554 DT:SPM 發(fā)送的郵件內(nèi)容包含了未被許可的信息盹憎，或被系統(tǒng)識別為垃圾郵件。請檢查是否有用戶發(fā)送病毒或者垃圾郵件铐刘；
被網(wǎng)易郵箱識別為垃圾郵件了陪每，有個歪招，就是把發(fā)送郵箱添加到cc里頭
helper.setCc(from);
