SpringBoot整合javaMail

再application.properyies中：

spring.mail.host=smtp.qq.com
spring.mail.username=[email protected]
#授权码g，在QQ邮箱客户端生成 修改成自己的  设置-账户-开启服务-获取授权码
spring.mail.password=mxltutotjccpbjgg
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true

再Controller中:

@RequestMapping("/mail2")
public void sendMail2() {
    MailUtil mailUtil = new MailUtil();
    Email email = new Email();
    email.setSubject("邮箱测试");
    email.setContent("测试成功");
    email.setEmail("[email protected]");
    SimpleMailMessage message = new SimpleMailMessage();
    message.setFrom(userName);
    message.setTo(email.getEmail());
    message.setSubject(email.getSubject());
    message.setText(email.getContent());
    mailUtil.start(javaMailSender,message);
}

MailUtil：

public class MailUtil {
    private Logger logger = LoggerFactory.getLogger(MailUtil.class);

    private ScheduledExecutorService service = Executors.newScheduledThreadPool(6);

    private final AtomicInteger count = new AtomicInteger(1);

    public void start(final JavaMailSender mailSender, final SimpleMailMessage message) {
        service.execute(new Runnable() {
            @Override
            public void run() {
                try {
                    if (count.get() == 2) {
                        service.shutdown();
                        logger.info("the task is down");
                    }
                    logger.info("start send email and the index is " + count);
                    mailSender.send(message);
                    logger.info("send email success");
                }catch (Exception e){
                    logger.error("send email fail" , e);
                }

            }
        });
    }

}
