Spring 启动 - 未呈现登陆 (index.html) 页面？

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?

Answer 1

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.

Answer 2

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".

Answer 3

try using full name with extension like index.html

Answer 4

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