//1、创建邮件对象

JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();

//2、发邮件人邮箱

javaMailSender.setUsername(emailConfig.getUsername());

//3、发邮件人邮箱密码（默认使用客户端的授权码）

//4、设置邮件服务器主机名 SMTP 服务器地址

javaMailSender.setHost(emailConfig.getHost());

//5、SMTP 服务器: 默认端口 换成腾讯云服务器后,需要将端口换成 465

// javaMailSender.setPort(465);

//6、//发送邮件协议名称

javaMailSender.setProtocol("smtp");

//7、编码格式

javaMailSender.setDefaultEncoding("UTF-8");

//8、创建连接对象，连接到邮箱服务器
