 刚才发现一bug，当附件名为中文时，会出现中文乱码问题，对sendMimeMessage方法进行了部分修改，如下：
   

               sun.misc.BASE64Encoder enc = new sun.misc.BASE64Encoder();
                files.add("src/SpringMail.java");
                files.add("src/applicationContext.xml");
                files.add("src/谢星星.xml");
                
                //向Multipart添加附件
                Iterator it = files.iterator();
             while (it.hasNext()) {
                    MimeBodyPart attachFile = new MimeBodyPart();
                    String filename = it.next().toString();
                    FileDataSource fds = new FileDataSource(filename);
                    attachFile.setDataHandler(new DataHandler(fds));
                    attachFile.setFileName("=?GBK?B?"+enc.encode(fds.getName().getBytes())+"?=");
                    mp.addBodyPart(attachFile);
                }
