Spring App won't work with JSP

Question

I am new to Spring Framework. Trying to make a Java based Spring MVC project. Here is my main application class

@SpringBootApplication
@ComponentScan
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

---

@Controller
public class HelloController {

    @RequestMapping("/")
    public String hello(){
        return "hello";
    }

}

When I run the project I get the error

There was an unexpected error (type=Not Found, status=404).
No message available

Why Spring can not display JSP files?

Answer 1

Add following to application.properties

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

Edit :You can refer sample project here

Below step is not required, but worth a try.

    <artifactId>tomcat-embed-jasper</artifactId>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
