提前准备：首先配置QQ邮箱->设置->账户->开启服务POP3/SMTP开启->获取授权码
-
下面是获取授权码的截图
image.png - 添加pom依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
- 配置application.properties
spring.mail.host=smtp.qq.com
spring.mail.username=1120845268@qq.com
spring.mail.password=amujxrblfdyobeeh
spring.mail.default-encoding=UTF-8
##如果不加下面3句,会报530错误
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
- Service类接口
public interface MailService {
/**
* 发送简单邮件
*/
void sendMail(String to,String subject,String content);
}
- 实现接口类
@Service("mailService")
public class MailServiceImpl implements MailService {
@Autowired
private JavaMailSender mailSender;
@Override
public void sendMail(String to, String subject, String content) {
SimpleMailMessage mailMessage=new SimpleMailMessage();
mailMessage.setFrom("1062273622@qq.com");//发起者
mailMessage.setTo(to);//接受者
mailMessage.setSubject(subject);
mailMessage.setText(content);
try {
mailSender.send(mailMessage);
System.out.println("发送简单邮件");
}catch (Exception e){
System.out.println("发送简单邮件失败");
}
}
}
- 定时任务
@Service
//@Async
public class TaskService {
@Autowired
private MailService mailService;
@Scheduled(cron = "*/6 * * * * ?")
//每6秒发送一次邮件
public void proces(){
mailService.sendMail("1284847585@qq.com","简单邮件","hello");
System.out.println("111");
}
}
