Spring boot - Not rendering the landing(index.html) page?

Question

I've tried the answers related to the question in stackoverflow. It did not work out.

Here is my project structure :

Controller: To render the index.html

@Controller
public class MainController {

    @RequestMapping(value="/",method = RequestMethod.GET)
    public String homepage(){
        System.out.println("Inside controller..");
        return "index";
    }
}

When i'm trying to hit the URL, it prints Inside controller.. but not rendering the index page. Tried using WebMvcConfigurerAdapter as well.

In browser, it displays some error like Whitelabel Error Page

Am I missing something out here?

Which technologies you are using at front end like angular ,thymeleaf ? — Ramesh Fadatare, Feb 14 '18 at 10:55
@KishorVelayutham open your `target` folder, check if there is `index.html` or not. — xingbin, Feb 14 '18 at 11:19
@user6690200, target folder ? index.html is in resources/templates folder — Kishor Velayutham, Feb 14 '18 at 11:23
It should be compiled to `target` folder by your IDE or maven at compile stage. At runtime, your application will seek `index.html` from `target` folder. So, it there it is, it means something wrong with your mapping configuration. If not, it means something wrong with your classpath. — xingbin, Feb 14 '18 at 11:26
could you try if change the return statement to "forward:index.html" and try — RSingh, Feb 14 '18 at 14:40
Whomever, Let me know the reason for downvote? Don't downvote just like that. Tell the reason so that i can change. Be professional. — Kishor Velayutham, Feb 15 '18 at 03:42
@RSingh, I tried using forward as well as redirect. Same error. — Kishor Velayutham, Feb 15 '18 at 04:07

Check for errors in the browser console. 'X-Frame-Options' may be set to 'DENY' that may block html page to load in the browser.

This How to disable 'X-Frame-Options' response header in Spring Security? may help.

Please check your project structure. Application, and other packages like model, controller etc. should be under the same package or on the same level. Also make sure there are no extra configuration on application.yml/properties file regarding "spring.thymeleaf.prefix".

I think you shouldn't return String. Try instead something like ModelAndView.

Yes, you can do that but it's not necessary so this is not the problem. Here's an example : https://spring.io/guides/gs/serving-web-content/ – Mickael Feb 14 '18 at 11:13
