有时候发送邮件需要带有附件，可以使用MimeMessageHelper来进行发送附件

JavaMailSenderImpl sender = new JavaMailSenderImpl();
sender.setHost("smtp.exmail.qq.com");
sender.setPort(587); // 默认就是25
sender.setUsername("username");
sender.setPassword("password");
sender.setDefaultEncoding("UTF-8");// 配置文件对象
Properties props = new Properties();
props.put("mail.smtp.auth", "true"); // 是否进行验证
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtps.ssl.checkserveridentity", "true");
props.put("mail.smtps.ssl.trust", "*");
Session session = Session.getInstance(props);
sender.setSession(session);MimeMessage mail = sender.createMimeMessage();MimeMessageHelper helper;
try {// 开启发送文件helper = new MimeMessageHelper(mail,true);
} catch (MessagingException e) {return false;
}try {helper.setTo(to); // 发送给谁helper.setCc(cc); // 抄送helper.setSubject(title); // 标题helper.setFrom("username"); // 来自// 邮件内容，第二个参数指定发送的是HTML格式helper.setText(textBody, true);// 发送附件helper.addAttachment(file.getName(),file);sender.send(mail); // 发送
}catch(Exception e) {
}
