Spring Boot 发送邮件全解析

1.前言

电子邮件虽然近几年有点“退火”，但是在开发中依然有举足轻重的地位。在比较正式的场合我们依然通过电子邮件来传递信息和回执。今天我们就来学一下如何在 Spring Boot 下发送电子邮件。

2. 依赖

  1.         <dependency>
  2.               <groupId>org.springframework.boot</groupId>
  3.               <artifactId>spring-boot-starter-mail</artifactId>
  4.         </dependency>

3. Service

  1. @Service
  2. public class EmailService {
  3.     @Autowired
  4.     private JavaMailSenderImpl javaMailSender;
  5.     //简单邮件测试
  6.     public void sendSimple(){
  7.         SimpleMailMessage message = new SimpleMailMessage();
  8.         message.setSubject("email测试");
  9.         message.setText("邮件测试内容");
  10.         message.setTo("xxx@sohu.com");
  11.         message.setFrom("xxx@sohu.com");
  12.         javaMailSender.send(message);
  13.     }
  14.     //复杂邮件测试
  15.     public void sendComplicated() throws MessagingException {
  16.         //创建一个复杂的消息邮件
  17.         MimeMessage mimeMessage = javaMailSender.createMimeMessage();
  18.         //用MimeMessageHelper来包装MimeMessage
  19.         MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage,true);
  20.         mimeMessageHelper.setSubject("email测试");
  21.         mimeMessageHelper.setText("邮件测试内容");
  22.         mimeMessageHelper.setTo("fanqixxxx@vip.qq.com");
  23.         mimeMessageHelper.setFrom("fanqixxxx@163.com");
  24.         mimeMessageHelper.addAttachment("meinv.jpg",new File("D:\\meinv.jpg"));
  25.         javaMailSender.send(mimeMessage);
  27.     }

4. application.properties

  1. #email
  2. spring.mail.username=dddddf@sohu.com
  3. #spring.mail.password   填写授权码
  4. spring.mail.password=ddddd
  5. #spring.mail.host   填写邮箱供应的SMTP地址
  6. spring.mail.host=smtp.sohu.com
  7. spring.mail.properties.mail.smtp.ssl.enable=true
