Spring MVC did not found mapping - spring-mvc

Question

I decided to move into world of Java EE from SE. I analyzed where I should start and most appealing option was spring MVC. I am unable to move forward because mapping for page is just not found.
I already checked some solutions here on stackoverflow and also on other sites on internet. Everything looks like it should just work, but there are no expected results.
I am using Maven with this pom.xml configuration

I would like to define servlet to handle pages using web.xml configuration
<?xml version="1.0" encoding="UTF-8"?>

<servlet>
<servlet-name>IndexPage</servlet-name>

</servlet>
<servlet-mapping>
<servlet-name>IndexPage</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
IndexPage-servlet.xml

I am starting application with class App.class
#SpringBootApplication
#EnableWebMvc
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
Also using controller IndexController.class
#Controller
#RequestMapping(value = "/")
public class IndexController {
#RequestMapping(method = RequestMethod.GET)
public String index(ModelMap model) {
model.addAttribute("message", "MVC index page");
return "index";
}
}
And i want make application entry point at index.jsp
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%# page import="java.time.LocalDateTime"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Just title</title>
</head>
<body>
<p>
Hello! Today is
<%=LocalDateTime.now()%></p>
<p>And now another messages ${message}</p>
</body>
</html>
My file structure is: https://imgur.com/a/WJg6ksA
My expectation was to see page, but instead of this I only get default 404 error: https://imgur.com/DS2zGAs
Also i noticed in log of spring application Page not found exception and also, when registering new servlet it should be also logged right ? There is only mention about default servlet.
Here is application log

I am not sure what I missed. I will appreciate any answer :)
