Spring通过MimeMessageHelper发送邮件，中文附件名出现乱码解决办法

1、当邮件内容是HTML语言时的中文问题

初始化MimeMessageHelper类的时候，设置为“UTF-8”.

JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();

MimeMessage mailMessage = senderImpl.createMimeMessage();

MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage, true, "utf-8");

2、邮件附件名为乱码问题

spring的文档里面说MimeMessageHelper设置了encoding，同时对title，text，attach产生作用，如果还是会出现乱码问题，解决办法为：

File file = new File(path);

messageHelper.addAttachment(MimeUtility.encodeWord(file.getName()), file);

项目开发代码：发送邮件实例：

JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();

senderImpl.setHost(mailSenderInfo.getHost());// 邮件发送服务器

senderImpl.setUsername(mailSenderInfo.getUserName());

senderImpl.setPassword(mailSenderInfo.getPassword());

Properties prop = new Properties();

prop.put("mail.smtp.auth", mailSenderInfo.getSmtpAuth());// 参数设为true，需服务器进行认证,认证用户名和密码是否正确

prop.put("mail.smtp.timeout",mailSenderInfo.getSmtpTimeout());

senderImpl.setJavaMailProperties(prop);

MimeMessage mailMessage = senderImpl.createMimeMessage();

MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage, true, "utf-8");

messageHelper.setTo(mailSenderInfo.getMailTo());// 收件人

messageHelper.setFrom(mailSenderInfo.getMailFrom());// 发件人

messageHelper.setCc(mailSenderInfo.getMailCc());// 邮件抄送

messageHelper.setSubject(mailSenderInfo.getMailSubject());// 邮件主题

messageHelper.setText(mailSenderInfo.getMailContent(), true);// 邮件内容

if (mailSenderInfo.getMailAttachments() != null) {

	for (String key : mailSenderInfo.getMailAttachments().keySet()) {

	String path = mailSenderInfo.getMailAttachments().get(key);

	File file = new File(path);

	messageHelper.addAttachment(MimeUtility.encodeWord(key), file);

	}

}

//图片问题暂时不贴了

senderImpl.send(mailMessage);
