学向勤中得，萤窗万卷书。这篇文章主要讲述#yyds干货盘点# SpringBoot 发送邮箱验证码（HTML模板）相关的知识，希望能为你提供帮助。
在本文中会继续详细的为大家讲解如何在 SpringBoot 中更简单的发送邮件。
导入 Mail 和 Thymeleaf 依赖

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

在 application.yml 文件中设置参数邮箱授权码获取教程：Java 使用 JavaMailSenderImpl 实现发送 QQ 邮件

#设置邮箱 spring: mail: host: smtp.qq.com#邮箱服务器地址 username: test@qq.com#邮箱账号 password: **********#邮箱授权码 default-encoding: utf-8#默认编码 #邮件发件人 mail: fromMail: fromAddress: test@qq.com

编写验证码的生成类

/** * @author Jie */ @Service public class VerificationCodeServiceImpl implements VerificationCodeService /** * 生产的验证码位数 */ private final int generateVerificationCodeLength=4; private final String[] metaCode="0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"; @Override public String generateVerificationCode() Random random = new Random(); StringBuilder verificationCode = new StringBuilder(); while (verificationCode.length()< generateVerificationCodeLength) int i = random.nextInt(metaCode.length); verificationCode.append(metaCode[i]); return verificationCode.toString();

编写邮件的服务类

/** * @author Jie */ @Service public class EmailServiceImpl implements EmailService @Autowired private javaMailSender mailSender; /** * 邮件发件人 */ @Value("$mail.fromMail.fromAddress") private String fromAddress; @Autowired TemplateEngine templateEngine; @Autowired private VerificationCodeService verificationCodeService; @Override public boolean sendEmailVerificationCode(String toAddress) //调用 VerificationCodeService 生产验证码 String verifyCode = verificationCodeService.generateVerificationCode(); //创建邮件正文 Context context = new Context(); context.setVariable("verifyCode", Arrays.asList(verifyCode.split(""))); //将模块引擎内容解析成html字符串 String emailContent = templateEngine.process("EmailVerificationCode", context); MimeMessage message=mailSender.createMimeMessage(); try //true表示需要创建一个multipart message MimeMessageHelper helper=new MimeMessageHelper(message,true); helper.setFrom(fromAddress); helper.setTo(toAddress); helper.setSubject("注册验证码"); helper.setText(emailContent,true); mailSender.send(message); return true; catch (MessagingException e) return false;

编写验证码 HTML 模板

< !DOCTYPE html> < html lang="en" xmlns:th="http://www.thymeleaf.org"> < head> < meta charset="UTF-8"> < title> 邮箱验证码< /title> < style> table width: 700px; margin: 0 auto; #top width: 700px; border-bottom: 1px solid #ccc; margin: 0 auto 30px; #top table font: 12px Tahoma, Arial, 宋体; height: 40px; #content width: 680px; padding: 0 10px; margin: 0 auto; #content_top line-height: 1.5; font-size: 14px; margin-bottom: 25px; color: #4d4d4d; #content_top strong display: block; margin-bottom: 15px; #content_top strong span color: #f60; font-size: 16px; #verificationCode color: #f60; font-size: 24px; #content_bottom margin-bottom: 30px; #content_bottom small display: block; margin-bottom: 20px; font-size: 12px; color: #747474; #bottom width: 700px; margin: 0 auto; #bottom div padding: 10px 10px 0; border-top: 1px solid #ccc; color: #747474; margin-bottom: 20px; line-height: 1.3em; font-size: 12px; #content_top strong span font-size: 18px; color: #FE4F70; #sign text-align: right; font-size: 18px; color: #FE4F70; font-weight: bold; #verificationCode height: 100px; width: 680px; text-align: center; margin: 30px 0; #verificationCode div height: 100px; width: 680px; .button color: #FE4F70; margin-left: 10px; height: 80px; width: 80px; resize: none; font-size: 42px; border: none; outline: none; padding: 10px 15px; background: #ededed; text-align: center; border-radius: 17px; box-shadow: 6px 6px 12px #cccccc, -6px -6px 12px #ffffff; .button:hover box-shadow: inset 6px 6px 4px #d1d1d1, inset -6px -6px 4px #ffffff; < /style> < /head> < body> < table> < tbody> < tr> < td> < div id="top"> < table> < tbody> < tr> < td> < /td> < /tr> < /tbody> < /table> < /div> < div id="content"> < div id="content_top"> < strong> 尊敬的用户：您好！< /strong> < strong> 您正在进行< span> 注册账号< /span> 操作，请在验证码中输入以下验证码完成操作： < /strong> < div id="verificationCode"> < button class="button" th:each="a:$verifyCode"> [[$a]]< /button> < /div> < /div> < div id="content_bottom"> < small> 注意：此操作可能会修改您的密码、登录邮箱或绑定手机。如非本人操作，请及时登录并修改密码以保证帐户安全 < br> （工作人员不会向你索取此验证码，请勿泄漏！) < /small> < /div> < /div> < div id="bottom"> < div> < p> 此为系统邮件，请勿回复< br> 请保管好您的邮箱，避免账号被他人盗用 < /p> < p id="sign"> ——Romantik< /p> < /div> < /div> < /td> < /tr> < /tbody> < /table> < /body>

测试

@SpringBootTest class ServiceApplicationTests @Autowired private EmailService emailService; @Test void contextLoads() boolean test = emailService.sendEmailVerificationCode("test.com"); System.out.println(test);
