如何解决以下发送电子邮件的异常？
how to I solve the following exception to sending the email?
我试图在我的一个项目中使用电子邮件实用程序 class。但是我遇到了以下错误。然后我将它分解为非常基本的代码，但我仍然无法发送电子邮件。
这是我得到的，
服务 class
包 com.test.email.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;
@Service
public class EmailService {
@Autowired
private JavaMailSender mailSender;
public void sendSimpleEmail(String toEmail, String body, String subject) {
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom("**********************************");
message.setTo(toEmail);
message.setText(body);
message.setSubject(subject);
mailSender.send(message);
System.out.println("Mail Send..........................................");
}
}
这是主要的class
import com.test.email.service.EmailService;
@SpringBootApplication
public class EmailtestApplication {
@Autowired
private EmailService emailService;
public static void main(String[] args) {
SpringApplication.run(EmailtestApplication.class, args);
System.out.println(" Spring boot application is running...................");
}
@EventListener(ApplicationReadyEvent.class)
public void triggerMail() throws MessagingException{
emailService.sendSimpleEmail("spring.boot.test83@gmail.com",
"This is the Email Body with attachement....",
"This is the Email Subject");
}
}
