SpringBoot does not find views

Question

I'm trying to write a simple SpringBoot Web Application to get started with the framework.

This is my structure:

src
`-main
   `-java
   `-resources
     `-static
     `-templates
   `-webapp
     `-WEB-INF
        `-jsp
            `-login.jsp 

I have a Controller like

@Controller
public class LoginController {

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

I've configurated the path where views has to be looked for in the application.properties like:

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
logging.level.org.springframework.web=DEBUG

I've also included the next dependency in pom.xml:

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

But when I go to http://localhost:8080/login I'm still having a 404 error. What am I missing?

EDIT: Here is the log from the IntelliJ Idea console. It seems like it finds the login.jsp, but for some reason return an error page.

Answer 1

You're missing dependancy in your pom.xml file.

Add jstl :

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
</dependency>

And remove the scope provided of tomcat-embed-jasper , because it's not provided by default by any spring-boot-starter.
