Java Spring Boot - getting images paths for emails to work in Freemarker

Question

I am new to Java Spring boot. -

I've got access to the Freemarker demo -- but how do I get hold of the image path for "\\src\\main\\resources\\static\\images"

            //Map < String, Object > model = new HashMap < String, Object > ();
            model.put("firstName", "Yashwant");
            model.put("lastName", "Chavan");
            model.put("imgPath", "resources/static/images/");

            mimeMessageHelper.setText(geContentFromTemplate(fmConfiguration, model), true);

            mailSender.send(mimeMessageHelper.getMimeMessage());
        } catch (MessagingException e) {
            System.out.println("ERROR - mimeMessage>>>");
            e.printStackTrace();
        }        
    }

}

public String geContentFromTemplate(Configuration fmConfiguration, Map < String, Object > model) {
    StringBuffer content = new StringBuffer();

    try {
        content.append(FreeMarkerTemplateUtils
            .processTemplateIntoString(fmConfiguration.getTemplate("email-template.html"), model));
    } catch (Exception e) {
        e.printStackTrace();
    }
    return content.toString();
}

Spring already provides this out of the box, where you can map such paths to static URIs.

What you will need to do is, define a Spring Configuration class, extend it with WebMvcConfigurerAdapter

This will give you access to addResourceHandlers method, override that method and provide the path to your static resources along with what URI you want to map it with. Am providing link to another SO answer which does the same thing.
