JavaMailSender对象未在Spring引导中发送电子邮件

我想实现忘记密码功能。我的应用程序应向员工发送电子邮件。JavaMailSender对象的send（）方法不起作用，并且我没有收到任何异常消息。我试过很多东西。例如：

我的ForgotPasswordController.java类（有问题的部分）：

我也尝试过587端口，但不起作用

@PostMapping("/forgot_password")
    public String processForgotPassword(HttpServletRequest request, Model model)
    {
        String email = request.getParameter("email");
        String token = RandomString.make(30);

        
        try 
        {
            employeeDAO.updateResetPasswordToken(token, email);
            String resetPasswordLink = Utility.getSiteURL(request) + "/reset_password?token=" + token;

            sendEmail(email, resetPasswordLink);
            model.addAttribute("message", "We have sent a reset password link to your email. Please check.");
             
        }
        catch (Exception e) 
        {
            model.addAttribute("error", "Error while sending email");
        }
             
        return "forgot_password_form";
    }
    
    public void sendEmail(String recipientEmail, String link) throws Exception
    {
        MimeMessage message = mailSender.createMimeMessage();              
        MimeMessageHelper helper = new MimeMessageHelper(message, true);
         
        helper.setFrom(new InternetAddress("svemir2212@gmail.com"));
        helper.setTo(recipientEmail);
         
        String subject = "Here's the link to reset your password";
         
        String content = "<p>Hello,</p>"
                + "<p>You have requested to reset your password.</p>"
                + "<p>Click the link below to change your password:</p>"
                + "<p><a href=\"" + link + "\">Change my password</a></p>"
                + "<br>"
                + "<p>Ignore this email if you do remember your password, "
                + "or you have not made the request.</p>";
         
        helper.setSubject(subject);
         
        helper.setText(content, true);
         
        mailSender.send(message);
    }
