//认证

Authenticator authenticator = new Authenticator() {

@Override

protected PasswordAuthentication getPasswordAuthentication() {

return new PasswordAuthentication("wang_yanlong_droid@163.com", "wyl123");

}

};

//属性

Properties props = new Properties();

props.setProperty("mail.smtp.host", "smtp.163.com");

props.put("mail.smtp.auth", "true");

Session session = Session.getDefaultInstance(props, authenticator);

//构建Mime消息

MimeMessage message = new MimeMessage(session);

//设置消息内容

try {

message.setFrom(new InternetAddress("wang_yanlong_droid@163.com","奥迪"));//发送人邮箱

message.setSubject("奥迪之道");

message.setRecipient(Message.RecipientType.TO, new InternetAddress(receiver));//接收人邮箱

//cc表示抄送 bcc 表示暗送

//message.setRecipient(Message.RecipientType.CC, new InternetAddress("抄送人邮箱"));

message.setRecipient(Message.RecipientType.BCC, new InternetAddress(copytoer));

//正文

//1、文本

MimeBodyPart body_text = new MimeBodyPart();

//body_text.setContent("----------","text/html;charset=utf-8");//这个src的写法，有部分邮箱看不到图片，比如微软的outlook邮箱

body_text.setContent("----------","text/html;charset=utf-8");

//2、图片

MimeBodyPart body_pic = new MimeBodyPart();

DataHandler picDataHandler = new DataHandler(new FileDataSource(new File(emailPicPath)));

body_pic.setDataHandler(picDataHandler);

//body_pic.setHeader("Content-ID", "");//这个也可以

body_pic.setContentID("");//和html链接的cid一致

//3、文本和图片关系

MimeMultipart relatedMultipart = new MimeMultipart();

relatedMultipart.addBodyPart(body_text);

relatedMultipart.addBodyPart(body_pic);

relatedMultipart.setSubType("related");

message.setContent(relatedMultipart);

//发送

Transport.send(message);

} catch (Exception e) {

e.printStackTrace();

}

我的问题，主要出在，src的写法上!
