Java实现发送邮箱验证码注册验证链接
Java实现发送邮箱验证码注册验证链接本⽂以163邮箱为例
1、准备(邮箱账号，邮箱必须设置POP3/SMTP/IMAP，设置步骤如下：)
》》步骤:1 开启授权码服务
》》步骤:2 ⼿机获取验证码
》》步骤:3 设置授权码
》》步骤:4 开启服务smtp/pop3/imap
》》步骤:5 开启成功，忘记授权码可重设
2、发送邮件的jar包(以下使⽤的为maven的pom坐标)
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4</version>
</dependency>
3、代码实现
