第一种：邮箱验证方法：
导入依赖：
<!-- mail依赖（发送短信的依赖） --><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId>
<!-- <version>3.1.5</version>--></dependency>
<!-- thymeleaf 依赖--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId>
<!-- <version>3.1.5</version>--></dependency>代码的实现
创建一个application.yml 文件
小提示：
一般用邮箱发送短信用 QQ 邮箱；(163 邮箱会过滤掉垃圾文件)，所以 QQ 文件比较稳定
