使用qq邮箱、163邮箱都行,其他有邮箱服务功能的都可以,这里以163邮箱为例
登录163邮箱,然后在设置那里选择POP3/SMTP/IMAP
开通IMAP/SMTP服务
开通后会有个授权码,记录下来,后面需要用到
添加pom文件
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
host是开通smtp时会有个地址的
username填的是邮箱账号
password填的是刚才上面开通smtp的授权码
,请注意不是邮箱密码,是授权码
注:
1.配置里面有个port的配置是默认端口,尽量不要自己去设置,不然可能会无法访问,以下配置是没有port的
2.配置错误可以尝试把注释去掉,因为有可能会因为复制过去的编码问题影响
spring:
mail:
host: smtp.163.com # smtp地址,开通的时候会显示
username: xxxxx@163.com # 你的邮箱账号
password: ****** # 你的邮箱授权码
properties:
mail:
smtp:
auth: true
starttls:
enable: true
protocol: smtp
这里是用了hutools的工具和lombok的Slf4j日志,视情况而添加
<!-- 工具类 -->

实现验证需要使用redis,本章节不介绍如何使用redis,请自行搭建
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<!-- jedis连接 -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
</dependency>
yaml配置
spring:
redis:
host: localhost # redis地址
port: 6379
database: 0
password: 123456 # 密码,无密码可不填
序列化配置,新建一个config包,并添加RedisConfig类
@Configuration
public class RedisConfig {
@Bean
public StringRedisTemplate redisTemplate(RedisConnectionFactory factory) {
StringRedisTemplate template = new StringRedisTemplate(factory);
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(new StringRedisSerializer());
return template;
}
}
@RestController @RequestMapping("/api") public class VerificationController { @Autowired private EmailService emailService; @Autowired private StringRedisTemplate redisTemplate; @PostMapping("/sendCode") public String sendCode(@RequestParam String email) { // 生成验证码 String code = String.valueOf((int)((Math.random() * 9 + 1) * 100000)); emailService.sendHtmlMail(email, "【邮箱验证码】欢迎使用xxx系统", "<p>您的邮箱验证码是:<p><p style=\" font-weight: bold;text-align: center;color: red;\">"+code+"</p>" ); // 存储验证码到 Redis,设置过期时间为 5 分钟 ValueOperations<String, String> ops = redisTemplate.opsForValue(); redisTemplate.delete(email); ops.set(email, code, 5, TimeUnit.MINUTES); return "验证码已发送"; } @PostMapping("/verifyCode") public String verifyCode(@RequestParam String email, @RequestParam String code) { // 从 Redis 获取验证码 ValueOperations<String, String> ops = redisTemplate.opsForValue(); String storedCode = ops.get(email); if (storedCode != null && storedCode.equals(code)) { redisTemplate.delete(email); return "邮箱验证成功"; } else { return "验证码错误或者已失效"; } } }
发送
验证
