Answer 1

private JavaMailSender javaMailSender;

You have to call the setter of this property In your case private MailSender mailSender; will be automatically injected by spring. But private JavaMailSender javaMailSender; will be null.

And you are calling javaMailSender.send(mimeMessage); resulting in null pointer.

Use (JavaMailSender)mailSender.send(mimeMessage); instead of javaMailSender.send(mimeMessage);
