This is my Controller class
#Controller
public class IController {
#RequestMapping(value="/first")
public String bankname(){
return "success";
}
}
main program which starts the springboot application
#SpringBootApplication
public class SpringbootIndex9Application {
public static void main(String[] args) {
SpringApplication.run(SpringbootIndex9Application.class, args);

This is my application.properties

Seems i got your problem. Perhaps you will have to add a dependency.
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
Add this dependency and try !

after trying multiple times on freemarker to work, I switched to thymeleaf and also faced the same problem. When returning the html file, it's just a string value and not the html file in the templates folder.
I don't know why it doesn't even start in console, when I watched youtube thymeleaf videos it shows in their console.
package com.example.demo;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class controller {
#GetMapping
public String getUser(Model model) {
model.addAttribute("something", "welcome to the club");
return "user";
}
}
here is the html file in main/resources/templates
<!DOCTYPE html>

Solved now, I replace #RestController with #Controller because #RestController adds #ResponseBody and prevents to get the view.
I want to use jsp with springboot, i add jasper dependency in my
pom.xml file, but when i run my springboot app it run corectly ,when i
type localhost:8080/home in my browser it show me this type of error.
i use getMapping annotation in palace of RequestMapping,I try it last
four days but it cannot shorout

The string returned by the home() handler method in your controller should be the name of the JSP view, without the extension. i.e. return "home";.
Try by adding the following dependency
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
</dependency>
Try this :
return "/Home.jsp";
I created just a simle springBoot application,and I want when i lunch
my application it retun me my jsp page in my browser. but when I type
localhost:8080 in my browser it return me this type of error"There was
an unexpected error (type=Not Found, status=404)."I added jasper
dependency got same error,I use jsp api dependency in place jasper i
got same error.
what is the reason i am not getting jsp page as a result,why it throws
error404
this type of error

Make sure that you are using proper jsp names, in project structure, jsp name is showing as "Katakile.jsp". But in controller you are returning "Katak.jsp".
If names are proper and still not working, please use "tomcat-embed-jasper" dependency instead of "tomcat-jasper" and remove the tomcat-jasper dependency from your classpath, if exists.
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<version>8.5.6</version>
<scope>provided</scope>
</dependency>
Just edit this line
#RequestMapping("/katak")
public String host() {
return "/Katakile.jsp";
}
And try acces localhost:8080/katak

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
org/eclipse/jdt/internal/compiler/env/INameEnvironment
In my case it worked by adding this dependency in pom.xml file.
It is needed to compile jsp don't know why tomcat-embed-jasper version is not working
<dependency>
<groupId>org.eclipse.jdt.core.compiler</groupId>
<artifactId>ecj</artifactId>

I downloaded my project from start.spring.io and the folder structure is as it appears in the picture and I can not add special-title.html page to home.jsp page.
I use the following commands for integration.
<jsp:include page="/WEB-INF/jsp/special-title.html"></jsp:include>
<jsp:include page="../WEB-INF/jsp/special-title.html"></jsp:include>
<jsp:include page="${pageContext.request.contextPath}/WEB-INF/jsp/special-title.html"></jsp:include>
However, I could not run these commands. Where am I making a mistake?

<h2>SPECIAL TITLE</h2>
Testing Url
http://localhost:7070/home
First move your special-title.html from WEB-INF to templates folder which is under resources.
Then in jsp file try adding line <%# include file="resources/templates/special-title.html"%> instead of <jsp:include page="/WEB-INF/jsp/special-title.html"></jsp:include>
To run html as jsp you can do one thing. Write a web.xml inside WEB-INF like this
<?xml version="1.0" encoding="utf-8"?>
