Spring-boot not find css even the HTML file

First: the HTML shows all the css and it cannot be recognized:

Second: The project runs just localhost but just give me the following output and does not start port 8080:

Process finished with exit code 0

File structure:

enter image description here

In HomeController I have:

@Controller()
public class HomeController {

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

The JS and CSS file paths look like this:

<link rel="stylesheet" href="css/bootstrap.min.css">

According to the docs I put them in the correct place and it should return index.html.

The issue causing the application to shut down immediately is caused by using WAR packaging, while running the application as a Spring boot application in IntelliJ.

Due to that, IntelliJ won't provide the necessary classes (because spring-boot-starter-tomcat has scope provided) and if it's missing, Spring boot won't know that it should run as a web application causing it to exit immediately.

To solve it either:

  1. Comment the provided scope:

    <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <!-- <scope>provided</scope> -->
</dependency>
  2. Run the application within Tomcat

When you fix the first problem, you still have another issue. You've placed your HTML files within the src/main/resources/templates folder, while this folder should only be used for dynamic templates (Thymeleaf, Freemarker, Groovy, Mustache, ...).

However, currently your HTML files are just plain, static HTML files, so you should put them in src/main/resources/static. If they aren't static HTML files, you should add a proper template engine, for example spring-boot-starter-thymeleaf.

If you use static templates, Spring boot will automatically resolve / to your index.html, so you can delete HomeController.

Finally, you said you're using the following CSS:

<link rel="stylesheet" href="css/main.css">

This is the right way to do it. However, on GitHub I noticed that you were using:

<link rel="stylesheet" href="../../resources/static/css/main.css">

This is not the right way. Even though the folder structures are correct, at runtime, Spring boot will run both public/ as templates/ on your context path root (/). This means that, even if you would have index.html in one folder and css/main.css in your other folder, it would still work.

Try returning a modelandview instead of raw string?

@RestController()
public class HomeController {

    @RequestMapping("/")
    public ModelAndView home(){
        return new ModelAndView("index");
    }
}

Teena is right use @RestController or if you use @Controller add the @ResponseBody annotation 

@Controller
@ResponseBody
@RequestMapping("/")
public class HomeController {

    @RequestMapping(method = RequestMethod.GET)
    public String get(){
        return "index";
    }

}

Can you annotate your HomeController class with @RestController annotation and deploy your app again

Adding spring-boot-starter-web to your dependencies will enable embedded tomcat as default servlet container and your application will be exposed on port 8080 by default.

Gradle:

compile("org.springframework.boot:spring-boot-starter-web")

Maven:

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