SpringBoot之邮件服务

1、添加pom依赖

?

1 2 3 4

<dependency>     <groupId>org.springframework.boot</groupId>     <artifactId>spring-boot-starter-mail</artifactId> </dependency>

2、获取smtp信息

我这里用的是qq邮箱发送，使用qq邮箱必须qq邮箱中 设置 >> 账户 >> 把POP3/SMTP服务开启 并且获取授权码

 

3、配置application.yml

 

 

 4、编写service实现类 service接口这里就不贴了

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

@Service public class MailServiceImpl implements MailService {     @Autowired     private JavaMailSender javaMailSender;     @Value("${spring.mail.username}")     private String fromUrl;     @Override     public void sendMail(String targetEmailUrl, String subject, String content) throws BusinessException {         SimpleMailMessage simpleMailMessage = new SimpleMailMessage();         simpleMailMessage.setFrom(fromUrl);         simpleMailMessage.setTo(targetEmailUrl);         simpleMailMessage.setSubject(subject);         simpleMailMessage.setText(content);         try {             javaMailSender.send(simpleMailMessage);         }catch (Exception e){             System.out.println("邮件发送失败，错误原因：" + e.getMessage());             throw new BusinessException(EmBusinessError.MAIL_SEND_FAIL,"邮件发送失败！",e.getMessage());         }       } }

5、调用service接口

?

1 2 3 4 5 6

@Autowired private MailService mailService; @Test void testMail() throws BusinessException {     mailService.sendMail("644332569@qq.com","绑定邮箱的验证码","验证码是：1234"); }
