index.html is not showing up (Request method 'GET' not supported)

Note: The code can be found here: https://github.com/silentsnooc/ema-server

So, I am cleaning up a quite messy project in which I try to serve static content as well as a small REST API. However, the application gets started as any other:

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

The REST API works for me but the web client is not. I've moved the web client resources into src/main/resources/static/

enter image description here

However, if I visit http://localhost:8080 what I get is 405 (Request method 'GET' not supported).

I do not understand what's missing - maybe I got the folder structure wrong?

Please let me know if you need any further information from my side.

As stated here @RestController is itself annotated with @ResponseBody which makes the response of your RequestMapping methods to be their return value. In your case that is the index.html string you're seeing in the web browser.

Replacing the @RestController annotation with @Controller should do the trick.

As for your error you have another class WordEmbeddingRestController which defines mappings for "/" as well, as "/" (or "" to be exact) is the default path value. Removing the @RestController annotation from this class will enable you to GET the desired html file.

Ignore that, GET is the default method if non was specified

For your edit:

You have to add the method you want to support to the @RequestMapping annotation for each of your methods. See this for more information. As an example:

@RequestMapping(path = "/", method = RequestMethod.GET)
public String index() {
    return "index.html";
}

Instead of using @RequestMapping with an explicit method you can also use shorthand annotations like @GetMapping and @PostMapping. Using these would reduce your code to someting like this:

@GetMapping("/")
public String index() {
    return "index.html";
}
