[FIXED] Error resolving template, template might not exist or might not be accessible by any of the configured Template Resolvers

Issue

I have the following controller:

@Controller
public class ConfigController {

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

However, I receive the following error when going to the route /:

There was an unexpected error (type=Internal Server Error, status=500).
Error resolving template [config], template might not exist or might not be accessible by any of the configured Template Resolvers
org.thymeleaf.exceptions.TemplateInputException: Error resolving template [config], template might not exist or might not be accessible by any of the configured Template Resolvers

I have a config.html file inside of resources/templates:

My pom.xml file: https://pastebin.com/yqYYuXWh

What am I doing wrong?

I have already tried adding a .html to the return of the controller function, but it still doesn't work.

After removing the spring-web dependency (I already had spring-boot-starter-web) I now get the following error when starting spring:

Cannot find template location: classpath:/templates/ (please add some templates or check your Thymeleaf configuration)

Solution

The issue is in your pom.xml file.

By adding this block to your build;

<resources>
    <resource>
        <directory>src/main/resources</directory>
        <filtering>true</filtering>
        <includes>
            <include>application.properties</include>
        </includes>
    </resource>
</resources>

You have overriden spring-boot-starter-parent's own resources block and caused it to include application.properties and nothing else. Remove it from your pom.xml and delete your target directory.
