JSP file not rendered in Spring Boot application

I have a Spring Boot web application that reads index.jsp and uses tomcat jasper to support JSP. However, the page is showing up as "There was an unexpected error (type=Not Found, status=404)." I suspect either the issue lies with the dependency.

pom.xml

<?xml version="1.0" encoding="UTF-8"?>

            </plugin>
        </plugins>
    </build>

</project>

index.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
Hello this shit works
</body>
</html>

The method runs as the print statement executes

@Controller
public class indexController {

// Tomcat Jasper to return jsp files
@RequestMapping("index")
public String getIndex() {
    System.out.println("test1");
    return "index.jsp";
}

File structure

if you are using spring starter project then that won't find the path you have to create new project as "dynamic web project" then you will get the folder web-inf and inside you can create views and the set path in properties file ... spring.mvc.view.prefix = /WEB-INF/views/ spring.mvc.view.suffix =.jsp

Add this dependency with other ( like web ) in your pom file.

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
        </dependency>
        
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
        </dependency>

In application.properties file add this config properties for file location (Your .jsp file location in class path)

Properties config:

        spring.mvc.view.prefix = /WEB-INF/views/
        spring.mvc.view.suffix =.jsp
        spring.mvc.static-path-pattern=/resources/**

OR

Class level config:

        @Configuration
        @EnableWebMvc
        @ComponentScan(basePackages= {"com.imran"})
        public class WebConfig implements WebMvcConfigurer {

            public void configureViewResolvers(ViewResolverRegistry registry) {
                registry.jsp().prefix("/WEB-INF/views/").suffix(".jsp");
            }
            public void addResourceHandlers(ResourceHandlerRegistry registry) {
                registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
            }


        }

and your controller will be like this (with out .jsp extension, just file name):

        @Controller
        public class indexController  {
            
            @RequestMapping(value = "/index", method = RequestMethod.GET)
            public String getIndex() {
                System.out.println("test1");
                return "index";
            }

        }

You can get some help from here if you need.
