Spring boot, JSP file as view not loading when run in IntelliJ

Question

I've created a simple Spring Boot Web Application in intelliJ. I've placed a simple .jsp file in the /src/main/resources/templates/ folder which contains some basic HTML.

I'm trying to return this in a controller but I'm getting 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'm assuming that Spring is unable to find the .jsp file, but there's no other errors appearing in the console to give me any further information.

Here's my simple controller;

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

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

}

I've 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'm using Spring Boot with embedded tomcat.

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

Finally, here is the structure of my project;

When running the application, I'm just using the 'Run' option in IntelliJ.

Answer 1

Setting working directory helped me --- by default, it was empty.

1. Edit your configuration for Spring boot application in Idea.

2. Set up the working directory, like it's done on a screenshot below:

Answer 2

I have recently experienced the same situation with below dependency:-

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

If I change the "scope" to "default", run the application with Intellij, it works fine.

But if I want to keep the "scope" as "provided", I have to use the command line (terminal) and execute the following:-

mvn clean spring-boot:run

It works for me.
