#RestController returning blank - spring

Question

I'm building my first Spring Boot application. But I can't get my requestMapping controller answer properly.
This is my main class:
package com.hello.world;
#SpringBootApplication
public class HelloWorld implements CommandLineRunner{
public static void main(String[] args) {
SpringApplication.run(HelloWorld.class, args);
}
#Override
public void run(String... args) throws Exception {
....
}
}
And this is my RestController:
package com.hello.world.controllers;
#RestController
public class UrlMappingControllers {
#RequestMapping("/hi")
String home() {
return "Hello World!";
}
}
If I take a look at the log I can see the "/hi" mapping:
restartedMain] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/hi]}" onto java.lang.String com.hello.world.controllers.UrlMappingControllers.home()
But when I access: http:localhost:8080/hi I get a blank page, I expected seing the "Hello World" text.
Why am I getting a blank page?
--- Edit ----
I've just realised that I am getting the blank page only when I add a cxf service. I think it is because the #configuration annotation on this class:
package com.hello.world.helloWorld.configuration;
#Configuration
public class CXFConfiguration {
#Bean
public ServletRegistrationBean dispatcherServlet() {
return new ServletRegistrationBean(new CXFServlet(), "/services/*");
}
#Bean(name=Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
SpringBus springBus = new SpringBus();
return springBus;
}
#Bean
public Endpoint endpointGreentingService() {
EndpointImpl endpoint = new EndpointImpl(springBus(), new GreetingServiceImpl());
endpoint.getFeatures().add(new LoggingFeature());
endpoint.publish("/GreetingService");
return endpoint;
}
}
Could it be related?

#RestController = #Controller + #ResponseBody which means that when you call your api at http:localhost:8080/hi the body of the response will contain the result of the home() handler, i-e "Hello world".
#RestControllerbehind the scene makes Spring MVC uses a Json Message Converter (by default) and all handler methods inside a class annoted with #RestController will return a JSON, that is why you do not see your text on your browser.
You can use Postman or ARC to test your app. Some web browsers like Firefox shows JSON directly.
