Using thymeleaf template for sending Mail with Spring

I'm trying to use Thymeleaf template for Spring application to send mail, I am taking the reference from here
https://github.com/thymeleaf/thymeleafexamples-springmail/

I am not getting any error but still it doesn't work ..I am using the same code as given in github still no luck ...Can anybody suggest how to do that??

Following is the method which is used to send mail ...

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);
}


If I remove the line which is creating the html body using thymeleaf and send a ordinary mail it works but not with template ..

This is the line which causing problem ... just redirect to error page

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


Following is the error I am getting ..

org.thymeleaf.exceptions.TemplateProcessingException: Resource resolution by ServletContext with org.thymeleaf.resourceresolver.ServletContextResourceResolver can only be performed when context implements org.thymeleaf.context.IWebContext [current context: org.thymeleaf.context.Context]

Answer

I got it working finally ... I changed the following line

 final Context ctx = new Context(locale);

with

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

Now I am able to send any template or attachment anything works great ..!!
