How do I fix HTTP Status 404 - Not Found on Intellij?-CodePudding

I've started my first job 2 months ago and it's been awhile since I've dealt with Spring.

I'm trying to run Tomcat server, and display "/home" but I'm getting 404 on it.

When I hover at my "home", IntelliJ is showing home.html.

Error

HTTP Status 404 – Not Found

Type Status Report

Message The requested resource [/home] is not available

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

Apache Tomcat/9.0.65

I've googled about it but it's doesn't fix it.

Here is my code.

HomeController.java

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

    @RequestMapping("/home")
public String landingPage() {
        return ("home");
    }
}

home.html

<!DOCTYPE html>
<html lang="en"
      xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

<h1>Landing page</h1>

</body>
</html>

I also tried to run my older projects that works but now it doesn't.

Thank you in advance!

try to use ModelAndView:

@RequestMapping("/")
public ModelAndView index () {
   ModelAndView modelAndView = new ModelAndView();
   modelAndView.setViewName("home");
   return modelAndView;
}

CodePudding user response：

You are using Spring Boot, which has an embedded Tomcat server. I believe you have a standalone Tomcat running on port 8080 on your machine, preventing Spring Boot from using its own embedded Tomcat.

Stop the standalone Tomcat and start the Spring Boot application again.
