1. Import jar package org.springframework.boot spring-boot-starter-mail 2.5.22. Configuration file

Test in a test class
@ SpringBootTestclass Sprintboot09TestApplicationTests {@ Autowired JavaMailSenderImpl mailSender; @ Test void contextLoads () {SimpleMailMessage mailMessage = new SimpleMailMessage (); mailMessage.setSubject (Hello); mailMessage.setText (thank you); mailMessage.setTo (2080038188@qq.com); mailMessage.setFrom (2080038188@qq.com); mailSender.send (mailMessage);}}
Then send it successfully, your QQ Mail will receive your own message, here is a great sense of achievement!
Key: in my test, there has been bug, looking for nearly half an hour to find, the result is that our springboot configuration file hit an extra space, the naked eye can not see, this kind of error, it is true to find good hard, once suspected is the jar package version or QQ Mail problem, the result is too much worry. Be sure to pay attention to the space problem in the springboot configuration file in the future!
Complex email send @ Testvoid contextLoads2 () throws MessagingException {/ / A complex email MimeMessage mimeMessage = mailSender.createMimeMessage (); / / assemble MimeMessageHelper helper = new MimeMessageHelper (mimeMessage, true); / / body helper.setSubject ("Hello ~ plus"); helper.setText ("Thank you for your crazy talk java series course ~
", true); / / Annex helper.addAttachment (" 1.jpg ", new File (" C:\\ Users\\ 86187\ Desktop\\ 1.jpg "); helper.setTo (" 2080038187@qq.com "); helper.setFrom (" 2080038187@qq.com "); mailSender.send (mimeMessage) } the above is the content of this article on "how to achieve automatic email sending task in springboot".
