springboot系列12：邮件发送

今天讲解springboot的spring-boot-starter-mail邮件发送，业务场景：注册验证，忘记密码或者是给用户发送营销信息等。

1、pom配置

org.springframework.boot
spring-boot-starter


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

2、application.propertis配置邮箱

#邮箱服务器地址
spring.mail.host=smtp.163.com
#用户名
spring.mail.username=z13128600812@163.com
#开通授权码
spring.mail.password=**********
spring.mail.default-encoding=UTF-8
spring.mail.properties.mail.smtp.auth=true
spring.mail.port=25
mail.fromMail.addr=z13128600812@163.com

3、发送邮件服务实现

@Component
public class MailServiceImpl implements MailService {
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private JavaMailSender mailSender;
@Value("${mail.fromMail.addr}")
private String from;
@Override
public void sendSimpleMail(String to, String subject, String content) {
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
message.setTo(to);
message.setSubject(subject);
message.setText(content);
try {
mailSender.send(message);
logger.info("简单邮件已经发送。");
} catch (Exception e) {
logger.error("发送简单邮件时发生异常", e);
}
}
}

4、测试类发送邮件

@RunWith(SpringRunner.class)
@SpringBootTest
public class MailServiceTest {
@Autowired
private MailService MailService;
@Test
public void testSimpleMail() throws Exception {
MailService.sendSimpleMail("1796969389@qq.com","test simple mail"," hello this is simple mail");
}
}
