How to read processed view jsp in spring?

Is there a way to get a view as String already processed?

I need to send emails and I want to avoid creating the html views in a String and better create a JSP view and be able to call it as a String .

I've dealt with TemplateEngine like this:

import org.springframework.restdocs.templates.Template;
import org.springframework.restdocs.templates.TemplateEngine;

@Service
public class LectorVistas
{
    @Autowired
    private TemplateEngine templateEngine;

    public String obtenerVista(Model model, String vistaNombre) throws 
    IOException {
        Template vista = templateEngine.compileTemplate(vistaNombre);

        String view = vista.render(model.asMap());

        return view;
   }
}

But it generates an exception:

  

No qualifying bean of type   [org.springframework.restdocs.templates.LectorVista] found for   dependency: expected at least 1 bean which qualifies as autowire   candidate for this dependence

Is there a better way to do it? What is the error in my code?
