Spring-boot not find css even the HTML file

Question

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:

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:

Comment the provided scope:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <!-- <scope>provided</scope> -->
</dependency>

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.

FYI, since I started with cloning/modifying you repository, I've forked it and created a pull request. github.com/drewjocham/Brock/pull/1

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

Try returning a modelandview instead of raw string?

@RestController()
public class HomeController {

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

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>

I have that. I think it is because I do not have my application.properties set up correctly. Thank you for your effort.

Jakub Kuryłowicz Over a year ago

Please show your application.properties then, we'll see what we can do.

Jakub Kuryłowicz Over a year ago

OK, you haven't added a templating engine, that's the issue, just add spring-boot-starter-thymeleaf to your dependencies. Another issue is that your index.html file is not valid HTML file (you don't use html ending tags for <meta>, <link>, <br> or img>), take a look at: thymeleaf.org/doc/articles/fromhtmltohtmlviahtml.html

Mike3355 Over a year ago

I removed the tags and added the dependency and still the same issue. I bought this template but I cannot get it to render. Git updated and I am not using thymeleaf right now.

AlieneilA Over a year ago

can you post your dependencies/pom.xml? Maybe it's one of the other dependencies that you are missing, because your app is now closing directly after it has started running

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";
    }

}
