使用 SpringBoot 发送邮件

使用 SpringBoot 发送邮件

思路：使用 thymeleaf 解析并渲染 html 模版，将 html 内容作为邮件内容发送

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

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

配置文件

server.port=8082
spring.mail.host=smtp.qq.com
spring.mail.protocol=smtp
spring.mail.default-encoding=UTF-8
spring.mail.password=授权码
spring.mail.username=xxxx@qq.com
spring.mail.port=587
spring.mail.properties.mail.stmp.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.debug=true

EmailSender.java

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.mail.MailProperties;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;
import org.thymeleaf.TemplateEngine;
import org.thymeleaf.context.Context;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.util.Date;

@Component
public class EmailSender {

    @Autowired
    JavaMailSender javaMailSender;
    @Autowired
    MailProperties mailProperties;
    @Autowired
    TemplateEngine templateEngine;

    public void sendSignUpCaptcha(String mailAddress, String code, Integer sec) {
        MimeMessage msg = javaMailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(msg);
        try {
            //设置邮件元信息
            helper.setTo("xxx@163.com");
            helper.setFrom(mailProperties.getUsername());
            helper.setSubject("验证码");
            helper.setSentDate(new Date());
            //模板渲染
            Context context = new Context();
            context.setVariable("name", "engureguo");
            context.setVariable("code", "833391");
            String mail = templateEngine.process("mail", context);
            helper.setText(mail, true);
            javaMailSender.send(msg);
            System.out.println("邮件发送成功！");
        } catch (MessagingException e) {
            System.out.println("邮件发送失败" + e.getMessage());
        }
    }

}

邮件 html 模版：templates/mail.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>欢迎注册 abc 网站！</title>
</head>
<style>
    .big-font {
        font-size: 25px;
    }
    .warning {
        color: red;
        background-color: bisque;
        display: inline;
    }
</style>
<body>
<h3>亲爱的 [[${name}]]，欢迎注册 abc 网站！</h3>

<p>您的<b>注册验证码</b>是：<b class="big-font"> [[${code}]] </b></p>

<p class="warning">如果您并没有注册 abc 网站，请忽略该邮件！</p>

</body>
</html>
