Spring Boot入门——邮件发送

1、引入依赖

    <!-- mail依赖 -->

       <dependency>

        <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-mail</artifactId>

    </dependency>

2、参数配置

　　在application.properties中配置邮件相关的参数

spring.thymeleaf.cache=false

spring.mail.host=smtp.qq.com

spring.mail.username=***@qq.com

spring.mail.password=ymwrdffauajebgde //此处的密码时qq邮箱的授权码

spring.mail.properties.mail.smtp.auth=true

spring.mail.properties.mail.smtp.starttls.enable=true

spring.mail.properties.mail.smtp.stattls.required=true

3、邮件Service代码

@Service

public class MailService {

    @Value("${spring.mail.username}")

    private String from;

    @Autowired

    private JavaMailSender sender;

    /*发送邮件的方法*/

    public void sendSimple(String to, String title, String content){

        SimpleMailMessage message = new SimpleMailMessage();

        message.setFrom(from); //发送者

        message.setTo(to); //接受者

        message.setSubject(title); //发送标题

        message.setText(content);  //发送内容

        sender.send(message);

        System.out.println("邮件发送成功");

    }

}

4、编写页面代码

<!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">邮件发送</h1>

    <form action="sendMail" method="post">

        <p>选择文件: <input type="text" name="title"/></p>

        <p><input type="submit" value="提交"/></p>

    </form>

</body>

</html>

5、邮件请求处理

@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";

    }

}

6、测试
