JSP file does not load in browser but file name is displayed as String in browser in spring Boot Application

index.jsp or any .jsp file (.html files as well), I can't display in the browser rather file name is displayed as a string in the browser when I use string type method for index method. However, if I use ModelAndView class then it works fine. How I can display a page using string type method ? I have gone through lots of examples and visited many sites including stackoverflow.com. Bellow all related files:

  1. Controller Class

    @SpringBootApplication
public class DemoApplication {

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

  2. @RestController
public class AppController extends SpringBootServletInitializer {

/*following method don't works*/
@RequestMapping("/home")
public String index(){
return "index";
}
/*following method works fine*/
/*   @RequestMapping("/home")
public ModelAndView modelAndView(){
return new ModelAndView("index");
}*/
}

  3. POM.xml

    <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<!-- JSTL for JSP -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
</dependency>

<!-- Need this to compile JSP -->
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
    <scope>provided</scope>
</dependency>

  4. Application.properties

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

  5. Output:

enter image description here

The expected page should be as follows: enter image description here Folder location is ok. I tried many times with different IDE and various combination of file location, and all dependency in pom. But every time getting error.

This is happening because the @RestController is sending the response to the browser body so to return JSP page use @Controller annotation instead.

Change @RestController to @Controller.

  • @Controller is used to mark classes as Spring MVC Controller.
  • @RestController is a convenience annotation that does nothing more than adding the @Controller and @ResponseBody annotations (see: [Javadoc][1])

See difference between both. Difference between spring @Controller and @RestController annotation

This happens due to @RestController annotation as this is used when we want to return things in JSON. --> You can change the annotation to @Controller else return Model containing your JSP file
