测试类

// 邮箱密码//
mailInfo.setPassword("密码就不给大家看了...");
// 发件人邮箱

mailInfo.setToAddress("13266716642@163.com");
// 邮件标题
mailInfo.setSubject("测试邮件");
// 邮件内容
StringBuffer buffer = new StringBuffer();
buffer.append("测试已成功！");
mailInfo.setContent(buffer.toString());
// 发送邮件
SimpleMailSender sms = new SimpleMailSender();
// 发送文体格式
sms.sendTextMail(mailInfo);
// 发送html格式
