java - 无法使用 Gmail SMTP 在 Spring Boot 中发送电子邮件

Question

我想在 Spring Boot 中使用 JavaMailSender 发送电子邮件。每当我运行我的项目时，我都会收到此错误:

org.springframework.mail.MailSendException: Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 530-5.5.1 Authentication Required. Learn more at 530 5.5.1 https://support.google.com/mail/answer/14257 ps2sm10628859pab.10 - gsmtp

我没有为我的帐户使用两步验证，密码也正确，我检查过了。

这是我的 application.properties 文件:

spring.mail.host = smtp.gmail.com
sprint.mail.username = apptestacc1234@gmail.com
sprint.mail.password = *******
send.from.email= apptestacc1234@gmail.com
spring.mail.properties.mail.smtp.auth = true;
spring.mail.properties.mail.smtp.starttls.enable = true
spring.mail.properties.mail.smtp.ssl.enable = true
spring.mail.properties.mail.socketFactory.port=587
spring.mail.properties.mail.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.socketFactory.fallback=false
spring.mail.smtp.port= 587

我的邮件服务类:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.MailException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Component;

@Component
public class MailService {

@Autowired
private JavaMailSender javaMailSender;


//public MailService(JavaMailSender javaMailSender){
//  this.javaMailSender = javaMailSender;
//}


public void sendMail() throws MailException{

    SimpleMailMessage mail = new SimpleMailMessage();
    mail.setTo("loonaishmita@gmail.com");
    mail.setFrom("apptestacc1234@gmail.com");
    mail.setSubject("Test");
    mail.setText("test mail");
    javaMailSender.send(mail);
}

这是我的 Controller :

@Controller
@EnableAutoConfiguration
public class MailController {
    @Autowired
    private MailService mailService;

@RequestMapping("/api/sendmail")
@ResponseBody
private String sendMail() {
    try{
        mailService.sendMail();
        return "mail sent";
    }catch(MailException e){
        e.printStackTrace();
    }
    return "thanks";
}

我在 stackoverflow 上关注了几乎所有与此问题相关的线程，但仍然无法弄清楚。请帮忙!

开启安全性较低的应用

然后重新测试发送邮件。
