    }
    public static void main(String[] args) {
    }
}

使用方式：

public static void main(String[] args) throws AddressException,MessagingException{
         MailSender mailSender=new MailSender();
         mailSender.setUsername("xxxxxxxxx@qq.com.cn");//企业邮箱账号  先申请一个企业邮箱
         mailSender.setPassword("1234asdfASDF"); //企业邮箱密码
         //腾讯企业邮箱的POP3服务器地址是pop.exmail.qq.com，其端口号为995，SMTP服务器地址是smtp.exmail.qq.com，端口号为465，但都是要开启SSL。
         mailSender.setHost("smtp.exmail.qq.com");//企业邮箱协议
         mailSender.setPort("465");//端口
         mailSender.init();
         mailSender.sendSimpleText("xxxxxxx@qq.com", "验证码", "123456");
}
