Deploying Spring Boot App in Wildfly 9.0.2

Question

I want to deploy a simple Spring Boot Rest app into a Wildfly 9.0.2 server. It seems to deploy but can't access any of the services.

I have been following various instructions such as: https://docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html

but still doesn't seem to work for me.

This is my pom.xml file

<?xml version="1.0" encoding="UTF-8"?>

And here is my application / controller class:

@SpringBootApplication
@ComponentScan
@EnableAutoConfiguration
public class ConfigAppApplication extends     
    SpringBootServletInitializer {

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

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

    @RestController
    class ConfigController {

    @RequestMapping("/hello")
    public String hello() {
        return "hello world";
    }
}

I deploy it on the $JBOSS_HOME/standalone/deployments and it tells me it is deployed.

15:51:12,008 INFO  [org.jboss.as.server] (DeploymentScanner-threads - 1) WFLYSRV0016: Replaced deployment "config-app-0.0.1-SNAPSHOT.war" with deployment "config-app-0.0.1-SNAPSHOT.war"

and I get the marker file:

config-app-0.0.1-SNAPSHOT.war.deployed

The jmx console tells me the application is enabled too. Whenever I try and access the endpoint e.g. when I try and access the root-context I get a 403 forbidden, but when I try and access the rest resource e.g. localhost:8080/config-app/hello I get a 404 error.

Any ideas what I am doing wrong?

Thanks

Wildfly uses undertow servlet container. Try adding support for that in your application.
