1.java代码：

/**
* 发送带附件的邮件
* @param sender 邮件发送器
* @param fileUrl 附件的绝对路径
* @throws Exception
*/
private void sendMimeMessage(final JavaMailSender sender,final String fileUrl) throws Exception {
//附件文件集合
final List files = new ArrayList();
MimeMessagePreparator mimeMail = new MimeMessagePreparator() {
public void prepare(MimeMessage mimeMessage) throws MessagingException {
try {
mimeMessage.setRecipient(Message.RecipientType.TO,
new InternetAddress("[e-mail]"));//收件人邮箱
mimeMessage.setFrom(new InternetAddress("[e-mail]"));//发件人邮箱
mimeMessage.setSubject("修改后的文件", "gb2312"); //邮件主题
Multipart mp = new MimeMultipart();//Multipart代表正文
MimeBodyPart content = new MimeBodyPart();
content.setText("spring文件，请查收!");//邮件内容
mp.addBodyPart(content);
//向Multipart添加附件
files.add(fileUrl);//fileUrl文件的绝对路径
Iterator it = files.iterator();
while(it.hasNext()) {
sun.misc.BASE64Encoder enc = new sun.misc.BASE64Encoder();
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);
}
files.clear();
//向MimeMessage添加Multipart
mimeMessage.setContent(mp);
mimeMessage.setSentDate(new Date());
} catch (AddressException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (javax.mail.MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
};

//发送带附件的邮件
sender.send(mimeMail);
System.out.println("邮件发送成功!");
}

2.配制文件

<!-- Spring发送邮件 -->
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host">
<value>smtp.126.com</value>
</property>
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.auth">true</prop>
<prop key="mail.smtp.timeout">25000</prop>
</props>
</property>
<property name="username">
<!-- 发件人用户名（邮箱号） -->
<value>chen123456789</value>
</property>
<property name="password">
<!-- 发件人邮箱密码 -->
<value>xxxxxxx</value>
</property>
</bean>
