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); } }
