我通过使用Sender获得了SSLHandshakeException。我已经指定了我在下面编写的所有代码段和属性文件。我应该做些什么来修复这个错误？

日志错误

Mail sending is started

  nested exception is:

应用程序属性

spring.mail.host=smtp.gmail.com
spring.mail.port=587
spring.mail.username= myemail
spring.mail.password= mypass
spring.mail.properties.mail.smtp.auth=true

服务层

@Service
public class SendEmailService {

    @Autowired
    private JavaMailSender javaMailSender;

    public void sendEmail(String to, String body, String topic){
        try {
            System.out.println("Mail sending is started");
            SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
            simpleMailMessage.setFrom("mail@mail.com");
            simpleMailMessage.setTo(to);
            simpleMailMessage.setSubject(topic);
            simpleMailMessage.setText(body);
            javaMailSender.send(simpleMailMessage);
            System.out.println("Mail sending is completed");
        }catch (Exception e){
            System.out.println("Error occured: "+e.getMessage());
        }
    }
}

SpringBootApplication类

@SpringBootApplication
public class MailSenderApplication {

    @Autowired
    SendEmailService sendEmailService;

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

    @EventListener(ApplicationReadyEvent.class)
    public void triggerWhenStarts(){
        sendEmailService.sendEmail("mutlueren01@gmail.com","This e-mail has sending by Spring Boot","Spring Boot Mail Sender TEST");
    }
}
