Spring boot - Whitelabel Error Page

Question

I am new on spring-boot. I have an error when I start my spring-boot application on the port 8080. I get Whitelabel Error Page.

I have created a very simple html page in /src/main/resources/templates/.

Here is my pom.xml.

            </plugin>
        </plugins>
    </build>
</project>

Here is the controller of my application

public class BanqueController {

    @Autowired
    private IBanqueMetier banqueMetier;

    @RequestMapping("/operations")
    public String index()
    {
        return "comptes";
    }
}

The html that should be return is this one

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>MyBanQ</title>
</head>
<body>
    <h3>Test</h3>
</body>
</html>

The main application is below. I have tried the solution proposed here Springboot Whitelabel Error Page, but it doesn't work for me.

@SpringBootApplication
public class MyBanQApplication implements CommandLineRunner {

    public static void main(String[] args) {
         SpringApplication.run(MyBanQApplication.class, args);
    }

}

Add the annotation @Controller to your controller class.And your html file name should be "comptes" as you have mention in your index function.
