/**
 * 创建一封复杂邮件（文本+图片+附件）
 */
public class CreateMimeMessage {
 public static MimeMessage createMimeMessage(Session session, String myMail, String toMail) throws Exception {
 // 1. 创建邮件对象
 MimeMessage message = new MimeMessage(session);

 // 2. From: 发件人
 message.setFrom(new InternetAddress(myMail, "我的测试邮件_发件人昵称", "UTF-8"));

 // 3. To: 收件人（可以增加多个收件人、抄送、密送）
 message.addRecipient(RecipientType.TO, new InternetAddress(toMail, "我的测试邮件_收件人昵称", "UTF-8"));

 // 4. Subject: 邮件主题
 message.setSubject("TEST邮件主题（文本+图片+附件）", "UTF-8");

 // 抄送人
 Address ccAddress = new InternetAddress("*********@qq.com", "我的测试邮件_抄送人昵称", "UTF-8");
 message.addRecipient(Message.RecipientType.CC, ccAddress);

 /*
 * 下面是邮件内容的创建:
 */

 // 5. 创建图片“节点”
 MimeBodyPart image = new MimeBodyPart();
 File file = new File("D:\\Chat_Software\\sky.JPG");
 DataHandler dh = new DataHandler(new FileDataSource(file)); // 读取本地文件
 image.setDataHandler(dh); // 将图片数据添加到“节点”
 // image.setContentID("image_fairy_tail");// 为“节点”设置一个唯一编号（在文本“节点”将引用该ID）
 image.setFileName(MimeUtility.encodeText(file.getName()));
 
 // 6. 创建文本“节点”
 MimeBodyPart text = new MimeBodyPart();
 // text.setContent("这是一张图片<br/>测试图片<br/><img
 // src='cid:image_fairy_tail'/>", "text/html;charset=UTF-8");
 text.setContent("这是一张图片<br/>测试图片", "text/html;charset=UTF-8");

 // 7. （文本+图片）设置 文本 和 图片 “节点”的关系（将 文本 和 图片 “节点”合成一个混合“节点”）
 MimeMultipart mm_text_image = new MimeMultipart();
 mm_text_image.addBodyPart(text);
 mm_text_image.addBodyPart(image);
 mm_text_image.setSubType("related"); // 关联关系

 // 8. 将 文本+图片 的混合“节点”封装成一个普通“节点”
 // 最终添加到邮件的 Content 是由多个 BodyPart 组成的 Multipart, 所以我们需要的是 BodyPart,
 // 上面的 mm_text_image 并非 BodyPart, 所有要把 mm_text_image 封装成一个 BodyPart
 MimeBodyPart text_image = new MimeBodyPart();
 text_image.setContent(mm_text_image);

 // 9. 创建附件“节点”
 MimeBodyPart attachment = new MimeBodyPart();
 File file2 = new File("E:\\boHaiBank\\Test\\test.xlsx");
 DataHandler dh2 = new DataHandler(new FileDataSource(file2)); // 读取本地文件
 attachment.setDataHandler(dh2); // 将附件数据添加到“节点”
 attachment.setFileName(MimeUtility.encodeText(dh2.getName())); // 设置附件的文件名

 // 10. 设置（文本+图片）和 附件 的关系（合成一个大的混合“节点” / Multipart ）
 MimeMultipart mm = new MimeMultipart();
 mm.addBodyPart(text_image);
 mm.addBodyPart(attachment); // 如果有多个附件，可以创建多个多次添加
 mm.setSubType("mixed"); // 混合关系

 // 11. 设置整个邮件的关系（将最终的混合“节点”作为邮件的内容添加到邮件对象）
 message.setContent(mm);

 // 12. 设置发件时间
 message.setSentDate(new Date());

 // 13. 保存上面的所有设置
 message.saveChanges();

 return message;
