本文介绍了一个使用Spring Mail模块发送包含附件的HTML格式邮件的Java示例。该示例展示了如何配置邮件发送器，设置邮件内容及附件，并通过Spring框架进行依赖注入。

java代码：

import java.io.File;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;

public class SendMail {
 private JavaMailSender sender;

 public void sendMessage(String[] to, String from, String subject) throws MessagingException {
  MimeMessage msg = sender.createMimeMessage();
  MimeMessageHelper helper = new MimeMessageHelper(msg, true, "GB2312");

  helper.setTo(to);
  helper.setFrom(from);
  helper.setSubject(subject);

  helper.setText("<html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=gb2312\"></head><body><h1><a href='#'>郁闷!"
    + "</body></html>", true);

  // add the rar file
  FileSystemResource rarfile = new FileSystemResource(new File("D:/workspace/netbar-dw/src/netbar/dw/util/SendMail.java"));
  helper.addAttachment("SendMail.java", rarfile);

  sender.send(msg);
 }

 public JavaMailSender getSender() {
  return sender;
 }

 public void setSender(JavaMailSender sender) {
  this.sender = sender;
 }
 public static void main(String[] args) throws MessagingException {
  ApplicationContext context=new ClassPathXmlApplicationContext("spring-mail.xml");
  SendMail send=(SendMail) context.getBean("sendMail");
  String [] to={"123@123.com","456@123.com"};
  send.sendMessage(to,"123@123.com", "test");
 }
}
