使用百万美元模板发送Mail with Spring

Question

我试图用Thymeleaf模板Spring应用程序发送邮件时,我从这里走的参考 https://github.com/thymeleaf/thymeleafexamples-springmail/

我没有得到任何错误但仍然无法正常工作..我使用github中给出的相同代码仍然没有运气...任何人都可以建议怎么做？

以下是用于发送邮件的方法...

public void sendSimpleMail(
        final String recipientName, final String recipientEmail, final Locale locale) 
        throws MessagingException {
    final Context ctx = new Context(locale);
    ctx.setVariable("name", recipientName);
    ctx.setVariable("subscriptionDate", new Date());
    ctx.setVariable("hobbies", Arrays.asList("Cinema", "Sports", "Music"));
    final MimeMessage mimeMessage = this.mailSender.createMimeMessage();
    final MimeMessageHelper message = new MimeMessageHelper(mimeMessage, "UTF-8");
    message.setSubject("Example HTML email (simple)");
    message.setFrom("thymeleaf@example.com");
    message.setTo(recipientEmail);
    // Create the HTML body using Thymeleaf
    final String htmlContent = this.templateEngine.process("email-simple.html", ctx);
    message.setText(htmlContent /* isHtml */);

    // Send email
    System.out.println("........");
   this.mailSender.send(mimeMessage);
}

如果我删除使用thymeleaf创建html主体的行并发送普通邮件,它可以工作,但不能使用模板..

这是引起问题的线......只是重定向到错误页面

final String htmlContent = this.templateEngine.process("email-simple.html", ctx);

以下是我得到的错误..

Answer 1

我终于开始工作......我改变了以下几行

 final Context ctx = new Context(locale);

同

final WebContext ctx = new WebContext(request,request.getContext(),locale);

现在我可以发送任何模板或附件任何有用的东西.. !!
