从spring boot应用程序发送电子邮件遇到麻烦

Question

我一直试图通过spring boot发送电子邮件，我似乎不能成功。我已经使用javamail api很长时间了，但是我想把springboot和spring邮件一起使用。

public class SendMail {

    @Autowired
    private JavaMailSender javaMailSender;

    public void sendingMail(String to, String subject, String body) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setTo(to);
        message.setSubject(subject);
        message.setText(body);
        javaMailSender.send(message);
    }

}

这是我的邮件

@Controller
public class ExamPle {

    @Autowired
    private SendMail  sendMail;

    @RequestMapping("/he")
    public String homePage() {
        sendMail.sendingMail("[e-mail]", "Welcome George", "Sample Message here");
        return "Sent";
        }
}

我的pom文件中已经有sprint-boot-starter-mail，但我一直收到这个错误消息。我甚至看过youtube上关于如何做到这一点的教程视频，但它并不起作用。我使用的是spring工具套件版本:3.9.0.发行版。

我已经卸载了我的jdk和STS并安装了新的副本

这管用。

@Service
public class SendMail {

@Autowired
private JavaMailSender javaMailSender;

  public void sendingMail(String to, String subject, String body) {
    MimeMessage message=javaMailSender.createMimeMessage();
    MimeMessageHelper helper;
    helper=new MimeMessageHelper(message,true);
    helper.setTo(to);
    helper.setSubject(subject);
    helper.setText(body);
    javaMailSender.send(message);

 }}
