@Component
class AsyncTask {

    private JavaMailSenderImpl mailSender;
    private MailSender sender;
    private MailProperties mailProperties;

    public AsyncTask(MailSender sender, MailProperties mailProperties, JavaMailSenderImpl mailSender) {
        this.sender = sender;
        this.mailProperties = mailProperties;

        //邮件设置2：一个复杂的邮件
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);

        helper.setSubject(title);
        helper.setText(content);

        //发送附件
        helper.addAttachment("1.jpg", new File(""));

@Controller
@RequestMapping("/mail")
public class MailController {
    private MailSender sender;
    private MailProperties mailProperties;
    private AsyncTask asyncTask;

    public MailController(MailSender sender, MailProperties mailProperties, AsyncTask asyncTask) {
        this.sender = sender;
        this.mailProperties = mailProperties;
        this.asyncTask = asyncTask;
    }

    @GetMapping("/index")
    public ModelAndView index() {
        return new ModelAndView("mail/index");
    }

    public void sendMail(String address, String title, String content) {
        SimpleMailMessage mailMessage = new SimpleMailMessage();
        mailMessage.setFrom(mailProperties.getUsername());
        mailMessage.setSubject(title);
        mailMessage.setTo(address);
        mailMessage.setText(content);

        sender.send(mailMessage);
    }

    //同步发送邮件
    @GetMapping("/send")
    public ModelAndView send(String address, String title, String content) {
        this.sendMail(address, title, content);
        return new ModelAndView("/mail/index");
    }

    //异步发送邮件
    @ResponseBody
    @PostMapping("/send/async")
    public String sendAsync(String address, String title, String content) {
        asyncTask.sendMail(address, title, content);
        System.out.println("发送邮件完毕");
        return "发送成功";
    }
}

在启动程序上加@EnableAsync

@EnableAsync
@SpringBootApplication
public class Springboot08EmailApplication {

    public static void main(String[] args) {
        SpringApplication.run(Springboot08EmailApplication.class, args);
    }
}
