Error in rendering jsp page using Spring boot?

I am trying to render a jsp page from my controller but I find this strange thing happening. When I run the application, it displays the actual html code of the page instead of displaying the view. This is quite strange what could I be doing wrong. So,it basically the whole html code of the welcome page is being displayed when I run my application.

    package com.example.DemoService;

    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;

    import java.util.Map;

    @Controller
    public class HelloController {



        @RequestMapping("/test")
        public String welcome(Map<String, Object> model) {
            model.put("message", "Raaj");
            return "welcome";
        }
    }

Jsp

    <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
    <html>
    <body>
    Hello ${message}
    </body>
    </html>

You have multiple things that you need to do:

  1. add in your application.properties this (presuming you have your jsp in src/webapp/WEB-INF/jsp)

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

  2. Try putting tomcat-embed-jasper with <scope>compile</scope>

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

There seems to be a bug, at least in IntelliJ, if you run it with <scope>provided</scope> it will not recognize the jsps. If you run with maven (mvn spring-boot:run) it runs fine regardless of the scope
