一、引入依賴html

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

二、參數配置spring

　　在application.properties中配置郵件相關的參數app

spring.thymeleaf.cache=false

spring.mail.host=smtp.qq.com
spring.mail.username=***@qq.com
spring.mail.password=ymwrdffauajebgde //此處的密碼時qq郵箱的受權碼
spring.mail.properties.mail.smtp.auth=true 
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.stattls.required=true

三、郵件Service代碼spring-boot

@Service
public class MailService {

    @Value("${spring.mail.username}")
    private String from;
    
    @Autowired
    private JavaMailSender sender;
    
    /*發送郵件的方法*/
    public void sendSimple(String to, String title, String content){
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from); //發送者
        message.setTo(to); //接受者
        message.setSubject(title); //發送標題
        message.setText(content);  //發送內容
        sender.send(message);
        
        System.out.println("郵件發送成功");
        
    }
}

四、編寫頁面代碼post

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"  
      xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
<head>
<meta charset="UTF-8" />
<title>Insert title here</title>
</head>
<body>
    <h1 th:inlines="text">郵件發送</h1>
    <form action="sendMail" method="post">
        <p>選擇文件: <input type="text" name="title"/></p>
        <p><input type="submit" value="提交"/></p>
    </form>
</body>
</html>

五、郵件請求處理測試

@Controller
public class MailController {

　　@Autowired
    private MailService mailService;
    
    private String to="***@qq.com";
    
    @RequestMapping("mail")
    public String mail(){
        return "/mail";
    }
    
    @RequestMapping("sendMail")
    @ResponseBody
    public String sendMail(@RequestParam("title")String title){
        System.out.println("-----title: " + title);
        mailService.sendSimple(to, title, title);
        return "success";
    }
}
