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=1729713807@qq.com
spring.mail.password=udmnwkaxeixofbae
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

第三行是开启的POP3的授权码 每个人都不一样

Service接口

public interface MailService {
    void sendMail(String to,String subject,String content);
}

Service实现类

@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");
        }
    }
}

每15秒发送一份电子邮件

@Service
//@Async
public class TaskService {
    @Autowired
    private MailService mailService;

    @Scheduled(cron = "*/15 * * * *  ?")
    public void proces(){
        mailService.sendMail("86884571@qq.com","简单邮件","我是测试");
        System.out.println("111");
    }
}
