Spring boot, JSP file as view does not load when IntellJ starts

Question

I created a simple Spring Boot web application in intelliJ. I put a simple .jsp file in the / src / main / resources / templates / folder, which contains the basic HTML code.

I try to return this in the controller, but I get this error;

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).
No message available

I assume Spring cannot find the .jsp file, but there were no other errors in the console that could give me more information.

Here is my simple controller;

@Controller
@RequestMapping("/test")
public class TestController {

    @RequestMapping("")
    public ModelAndView index() {
        return new ModelAndView("test");
    }

}

I included the following in my application.properties file:

spring.mvc.view.prefix = /templates/
spring.mvc.view.suffix = .jsp

My POM file includes the following dependencies;

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jersey</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
        </dependency>

I am using Spring Boot with a built-in cat.

I tried changing the path to the views inside application.properties; classpath: / templates /, but that also didn't make any difference.

Finally, here is the structure of my project;
