当root URL命中时，Wildfly上的Spring不会呈现index.html

Question

Due to project requirements I have to deploy a Spring application to a server incapable of running Tomcat and only capable of running WildFly. When I had a very simple project running on Tomcat and the root URL was hit (localhost:8080) it rendered my index.html . Since migrating to WildFly and refactoring the structure of my project, localhost:8080 no longer renders the index.html but I can still reach other URLs.

I've tried to implement a jboss-web.xml file under BrassDucks/src/main/webapp/WEB-INF/jboss-web.xml like this:

<jboss-web>
    <context-root>Brass-Ducks</context-root>
</jboss-web>

Where Brass-Ducks is the artifactID but to no avail.

Consider my ApplicationConfig.java

package brass.ducks;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@Configuration
@ComponentScan
@EnableAutoConfiguration
public class ApplicationConfig extends SpringBootServletInitializer{

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(applicationClass);
    }

    private static Class<ApplicationConfig> applicationClass = ApplicationConfig.class;



}

@RestController
class GreetingController {

    @RequestMapping("/hello/{name}")
    String hello(@PathVariable String name) {
        return "Hello, " + name + "!";
    }
} 

and consider my Controller.java

package brass.ducks.application;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/")
public class Controller {

    @RequestMapping("/greet")
    @ResponseBody
    public String greeting() {
        return "Hello, there.";
    }
}

And finally should it be relevant, my folder structure:

localhost:8080/greet returns "Hello, there" and localhost:8080/hello/name returns "Hello name". How can I fix this?

Depending on your exact configuration something along the lines of this should work:

@Controller
public class LandingPageController {

@RequestMapping({"/","/home"})
public String showHomePage(Map<String, Object> model) {
    return "/WEB-INF/index.html";   
   }
}

This is going to explicitly map / to index.html .
