Spring Boot uses Tencent QQ mailbox to send emails

It is relatively simple to send emails in Spring Boot, and it has become a fool. It takes two minutes to read it, three minutes to complete it, and five minutes to make this function is enough.
If you haven't done it in five minutes, please check whether your computer has development tools, whether the computer is too old, and whether the network is slow.

Add mail sending dependency in pom.xml

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-mail</artifactId>
		</dependency>

@RestController
@RequestMapping("/mail")
public class MailController {
    @Autowired
    JavaMailSender jms;

    @Autowired
    MailConfig mailConfig;

    @PostMapping(value = "/send")
    public JsonResult<String> postMail(@RequestBody MailDto mailDto) {
        try {
            SimpleMailMessage message = new SimpleMailMessage();
            message.setFrom(mailConfig.getUserEmail());
            message.setTo(mailDto.getTo()); //收件人邮箱地址
            message.setSubject(mailDto.getSubject());
            message.setText(mailDto.getText());
            jms.send(message);
        } catch (Exception e) {
            throw new MessageException(e.getMessage());
        }
        return JsonResult.success("success");
    }
    
}

POST ：

{
	"to":"[email protected]",
	"subject": "好久不见",
	"text":"好久不见了，你还好么？顺便问一下，想我了么"
}
