使用 Thymeleaf 处理 HTML 模板的模板解析期间发生错误

Question

I try to process a template with ThymeLeaf but i get org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "generatedTemplate.html") .

This is my code:

ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode(TemplateMode.HTML);

TemplateEngine templateEngine = new TemplateEngine();
templateEngine.setTemplateResolver(templateResolver);
Context context = new Context();

String html = templateEngine.process("generatedTemplate", context);

I tried to change the path by adding a prefix like this but it didn't help:

templateResolver.setPrefix("src/main/resources/");

Can this error be caused by something else than a path problem?

If needed i can give more details about my project structure.

Thanks

EDIT:

Here's the stack trace, it may help:

It happened that it was a path problem as expected. It comes from the fact that the default path change if i call the method from test class or from main class.
