在我的servlet中使用thymeleaf，找不到html模板文件

Question

I am trying to use thymeleaf to read an html template, remplace a variable in it and then send it as an email. However I am stuck at the part of reading the html template file.

This is the error i get:

The server encountered an internal error () that prevented it from fulfilling this request.</u></p><p><b>exception</b> <pre>org.thymeleaf.exceptions.TemplateInputException: Error resolving template &quot;invitationemail&quot;, template might not exist or might not be accessible by any of the configured Template Resolvers
    org.thymeleaf.TemplateRepository.getTemplate(TemplateRepository.java:247)
    org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1192)
    org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1148)
    org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1095)
    org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1008)
    org.thymeleaf.TemplateEngine.process(TemplateEngine.java:982)
    yesterscape.ses.SESManagement.sendInvitationEmail(SESManagement.java:69)
    yesterscape.users.InviteUserServlet.doPost(InviteUserServlet.java:68)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:637)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

So I am assumig it is because I am not properly setting my invitationemail.html file.

This is the code to read the email and change the value:

ClassLoaderTemplateResolver resolver = new ClassLoaderTemplateResolver();
resolver.setTemplateMode("HTML5");
resolver.setSuffix(".html");
TemplateEngine templateEngine = new TemplateEngine();
templateEngine.setTemplateResolver(resolver);
final Context context = new Context(Locale.US);
context.setVariable("name", nameFrom);
final String htmlVer = templateEngine.process("invitationemail", context);

As you can see, I am setting the suffix as .html and in the name of the file to process i am just typing "invitationemail". But still it cannot be found.

In what folder of my servlet architecture should I include the invitationemail.html file? I thought it should be in the WEB-INF folder, and this is where it currently is but I still have no luck.

Thanks in advice for any assistance you can provide.

Answer 1

Instead of ClassLoaderTemplateResolver use another ITemplateResolver implementation as follows

ServletContextTemplateResolver resolver = new ServletContextTemplateResolver();
resolver.setPrefix("/WEB-INF/template/");
resolver.setSuffix(".html");
resolver.setTemplateMode("HTML5");
// ... etc

And put you email template into /WEB-INF/template folder..

Problem fixed. When using the ClassLoaderTemplateResolver (which is the resolver needed for email content) the html files should be placed in the following directory:

WEB-INF/classes
