邮箱发送验证码工具类

1.邮箱支持引入到pom

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

      <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-core</artifactId>
            <version>5.4.0</version>
        </dependency>

 

2.验证码生成，随机数

 String verifCode = RandomUtil.randomNumbers(6);
