Spring Boot and JSP not rendering

I've been working on this for days trying to get it to work. Trying to use JSP with Spring Boot. I've been following the example at github. So many examples on the web have a web.xml file, yet the example on github, which is referenced many times on this forum, doesn't even have a web.xml. Also, when creating a Spring Boot Project, STS doesn't create a "webapp" directory with subdirectory "WEB-INF". I had to create those manually in Windows Explorer then refresh Project Explorer in STS to make them appear.

Regardless, I have followed the example as best I can but still can't get my index.jsp file to render in the browser when I type in http://localhost:8080 in the address field.

Any guidance would be appreciated.

This is what I have so far.
Directory structure:

application.properties:

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/jeddatae_editor
spring.datasource.username=webapp
spring.datasource.password=secret

index.jsp:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%
  String name = request.getParameter("name");
%>

  {
