spring boot：模板解析过程中发生错误

Question

我正在尝试使用 thymeleaf 在邮件消息中附加一个文件，但在发送它时发生了模板解析错误。

package com.report.tool.services; 
import java.nio.charset.StandardCharsets;
import java.util.Iterator;
import java.util.List;
import java.util.Properties;

import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
@Service("sendmail")
public class MailSendService {

 @Autowired
MailRepository  mailrepository;
@Autowired
UserRepo userRepo;
@Autowired
SpringTemplateEngine templateEngine;
JavaMailSender mailSender;

EmailModel datamodel;
HttpSession session;
//Mail send
 public Object sendMail(String filename) {
datamodel=new EmailModel();
try {
String usermail= "abc@abc.com"; 
//userRepo.findByToken("pPVHDe1ixjIEuNk").getEmail();


List<EmailMetaModel> mailmodel = mailrepository.findAll();
String email = null;
String pas = null;
for (Iterator iterator = mailmodel.iterator(); iterator.hasNext();) {
EmailMetaModel emailModel = (EmailMetaModel) iterator.next();
if (emailModel.getStatus() == true) {
email = emailModel.getEmail();
pas = emailModel.getEmailpassword();
}
}

String host = "smtp.gmail.com";
// Get system properties
Properties props = System.getProperties();
props.put("mail.smtp.host", host);
props.put("mail.smtps.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
Session s = Session.getInstance(props, null);

 MimeMessage message = new MimeMessage(s);

MimeMessageHelper helper = new MimeMessageHelper(message,
     MimeMessageHelper.MULTIPART_MODE_MIXED_RELATED,
    StandardCharsets.UTF_8.name());

 helper.addAttachment("logo.png", new ClassPathResource("Zeronsec.png"));

Context context = new Context();
//context.setVariable( );
String html = templateEngine.process("email-template", context);

helper.setTo(usermail);
helper.setText(html, true);
helper.setSubject("Any");
helper.setFrom(email);

message.setSubject("Thymleaf mail");
message.setText(html);




Transport tr = s.getTransport("smtps");
tr.connect(host, email, pas);
tr.sendMessage(message, message.getAllRecipients());
System.out.println("Mail Sent Successfully");
tr.close();

 } catch (Exception sfe) {

 System.out.println(sfe);

}

return "Mail sent"; 
} 
}

• 这个文件放在我项目的资源文件夹中。
• 我尝试了许多可能的情况，也访问了许多网站，但没有任何一个单独出现此错误。
• 请帮忙。 任何帮助，将不胜感激。

这仅是 HTML 模板的问题，对于 spring，您需要格式正确的 HTML，确保所有标签都已关闭。
