我正在尝试使用 ThymeLeaf 和 Spring 发送带有内联图像的电子邮件,但到目前为止没有成功。电子邮件已发送,但内联图像不会显示在电子邮件中。
该项目不是基于网络的(不是网站),而是桌面独立的,不是移动的
这是我获取图像文件的方式:
URL url = getClass().getResource("/LawFirmAdvisoryGroup.jpg");
File file = new File(url.getPath());
MultipartFile multipartFile = new MockMultipartFile(file.getName(),
file.getName(), "image/jpeg", IOUtils.toByteArray(input));
我的服务类:
@Autowired
private JavaMailSender mailSender;
@Autowired
private TemplateEngine templateEngine;
public void sendMailWithInline(final String recipientName, final String recipientEmail, final MultipartFile image, final byte[] imageBytes)
throws MessagingException {
final Context ctx = new Context();
ctx.setVariable("imageResourceName", image.getName()); // so that we can reference it from HTML
final MimeMessage mimeMessage = this.mailSender.createMimeMessage();
final MimeMessageHelper message
= new MimeMessageHelper(mimeMessage, true, "UTF-8");
message.setSubject("Inline Image");
message.setFrom("XXXX@yahoo.com");
message.setTo(recipientEmail);
// Add the inline image, referenced from the HTML code as "cid:${imageResourceName}"
final InputStreamSource imageSource = new ByteArrayResource(imageBytes);
message.addInline(image.getName(), imageSource, image.getContentType());
final String htmlContent = this.templateEngine.process("left_sidebar.html", ctx);
message.setText(htmlContent, true);
this.mailSender.send(mimeMessage);
}
HTML:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title th:remove="all">Email with inline image</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<p>
<img src="LawFirmAdvisoryGroup.jpg" th:src="'cid:' + ${imageResourceName}" />
</p>
</body>
</html>
最佳答案
只需将对 setText()
的调用向上移动几行即可。
MimeMessageHelper.addInLine()
的 javadoc说:
NOTE: Invoke
addInline
aftersetText(java.lang.String)
; else, mail readers might not be able to resolve inline references correctly.
