SpringBoot Does Not Display JSP

I am trying to display a simple JSP on SpringBoot, but the screen is not displayed.
A 404 error was displayed and I am doing various things, but it has not changed at all.
Could someone give me some advice?
[Procedure]
1. New for STS Starter Project
2. Add the following to pom.xml

<dependency>
    　　<groupId>org.apache.tomcat.embed</groupId>
    　　<artifactId>tomcat-embed-jasper</artifactId>
    　　<scope>provided</scope>
　　</dependency>

2. Add the following to application.properties

spring.mvc.view.prefix:/WEB-INF/views/ 
　spring.mvc.view.suffix: .jsp

3. Create a folder directly under the project folder

src\main\webapp\WEB-INF\views

4. Place login.jsp in the views folder above.
Login.jsp Contents

<%@pagelanguage="java" contentType="text/html;charset=UTF-8"
    　　pageEncoding="UTF-8"%>
　　<!DOCTYPE html PUBLIC"-//W3C//DTD HTML 4.01 Transitional//EN"http://www.w3.org/TR/html4/loose.dtd">
　　<html>
　　<head>
　　<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
　　<title>Hello, World! JPS</title>
　　</head>
　　  <body>
　　    <p>Hello, World! JSP</p>
　　  </body>
　　</html>

5.Create Controller Class

@Controller
public class LoginAction {    
    @RequestMapping(value="/", method=RequestMethod.GET)
    public String index() {
        return "login";
    }

6. Run on STS to access the following URL in your browser.

http://localhost:8081/

7. Browser displays 404 errors and does not display JSP.

**Whitelabel Error Page**
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

Verified that RequestMapping is calling the method when viewed in debug mode.
I've tried many things, but I'm still in trouble.
What's missing?

java spring-boot
