spring集成的邮件发送

        mailSender.setUsername("[email protected]");

    }

        //使用JavaMail的MimeMessage，支付更加复杂的邮件格式和内容

        MimeMessage msg = mailSender.createMimeMessage();

        //创建MimeMessageHelper对象，处理MimeMessage的辅助类

        helper.setTo("[email protected]");

        helper.setText("This is a mail with attachment");

        //加载文件资源，作为附件

        ClassPathResource file = new ClassPathResource("Chrysanthemum.jpg");

        //加入附件

        helper.addAttachment("attachment.jpg", file);

        mailSender.send(msg);

        helper.setFrom(mailSender.getUsername());

        helper.setTo("[email protected]");

        helper.setSubject("Rich content mail");

        //第二个参数true，表示text的内容为html，然后注意<img/>标签，src='cid:file'，'cid'是contentId的缩写，'file'是一个标记，需要在后面的代码中调用MimeMessageHelper的addInline方法替代成文件

        helper.setText(

                "<body><p>Hello Html Email</p><img src='cid:file'/></body>",

                true);

        FileSystemResource file = new FileSystemResource(

        helper.addInline("file", file);

        mailSender.send(msg);
