How to map to the path "/" index.html?

Question

Java

Good afternoon, I’m learning a spin, how, at the start of the application, would index.html be called by default?
that is, if the default path is localhost:8080/MakeYourDream - then I saw index.html on it.
All html files are here - /WEB-INF/view/
Where did I make a mistake or what did I not add?
web.xml

<servlet>
        <servlet-name>servlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/app-config.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>servlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring-servlet.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

spring-servlet

<bean id="templateResolve" class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver">
        <property name="prefix" value="/WEB-INF/view/"/>
        <property name="suffix" value=".html"/>
        <property name="templateMode" value="HTML5"/>
    </bean>

controller

@Controller
public class MainController {

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String index(Model model){
        model.addAttribute("message", "Hello index");
        return "index";
    }
}

So I DECIDED!! it's been 3 days!!!
What was the problem!?!? in that by default, maven creates a project and immediately lies index.jsp which will be the default page (unless, of course, it is configured by default to such a path / ) since I wanted to use thymleaf templates, I don’t need .jsp anymore, I need .html then I created the index.html page, but I didn’t delete the index.jsp page, but marked it as text (there is such a function in the idea, if more specifically - Mark as a plain text) because I thought this file would not participate with this label, BUT FUCK! WILL!!! In general, apparently during assembly, two files with the same names and even different extensions clashed, and I grabbed such an error.
I deleted the index.jsp file, everything worked)))
The treatment is simple, NEVER CREATE FILES WITH THE SAME NAMES.

It is you who needs to describe in the servlet container which application you will map by default. For cat Tom it is described here - https://tomcat.apache.org/tomcat-7.0-doc/default-s... (file $CATALINA_BASE/conf/web.xml) and here https://stackoverflow.com/questions /14325171/setti...
(you can place your war file as ROOT.war)
Well, smoke docks from your container.
