javamail发送excel附件

*

1，附件名乱码解决

Multipart mm = new MimeMultipart();
BodyPart mdp = new MimeBodyPart();

mdp.setFileName(MimeUtility.encodeWord(attachname));

2，新方法发送附件

public void sendAttachByTemplate(File file,
            TBaseMailset from, String toEmail,String attachname) {
        String subject = "薪酬通知邮件";
        try {
            getMailSession().setDebug(true);
            Message msg = new MimeMessage(getMailSession());
            //发件人
            if(from!=null&&!"".equals(from.getMail())){
                msg.setFrom(new InternetAddress(from.getMail()));//邮箱地址
            }else{
                msg.setFrom(new InternetAddress("lantuo103@163.com"));//邮箱地址
            }
            //收件人
            msg.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse(toEmail));
            //设置主题
            msg.setSubject(subject);
            //发送时间
            msg.setSentDate(new java.util.Date());

            // 添加附件
            Multipart mm = new MimeMultipart();
            BodyPart mdp = new MimeBodyPart();
            ///E:/JavaWorkspace/rs/WebRoot/WEB-INF/classes/xlsresult/ygxc.xls
            //File file = new File(this.getClass().getResource("/").getPath()+"xlsresult/ygxc.xls"); 
            FileDataSource fds = new FileDataSource(file);
            DataHandler dh = new DataHandler(fds);
            //mdp.setFileName("salary.xls");//设置后缀为xls的名字后就可以发送excel附件了
            //mdp.setFileName(attachname);//设置后缀为xls的名字后就可以发送excel附件了
            mdp.setFileName(MimeUtility.encodeWord(attachname));//设置后缀为xls的名字后就可以发送excel附件了
            
            //mdp.setFileName(URLEncoder.encode(attachname, "UTF-8"));
            
            mdp.setDataHandler(dh);
            mm.addBodyPart(mdp);
            msg.setContent(mm);
            
            Transport transport = mailSession.getTransport("smtp");
            //transport.connect("smtp.163.com", "lantuo103@163.com", "lantuo");
            if(from!=null){ //如果没有设置发送邮箱
                transport.connect(from.getServerHost(), from.getMail(), from.getMailPassword());
            }else{
                transport.connect("smtp.163.com", "lwww@163.com", "lwww");
            }
