Spring Boot: не удается получить доступ к контроллеру REST на локальном хосте (404)

Я пытаюсь адаптировать пример контроллера REST на веб-сайте Spring Boot. К сожалению, у меня есть следующая ошибка, когда я пытаюсь получить доступ к localhost:8080/item URL.

{
  "timestamp": 1436442596410,
  "status": 404,
  "error": "Not Found",
  "message": "No message available",
  "path": "/item"
}

Стартер-Применение:

package com.nice.application;
@SpringBootApplication // same as @Configuration @EnableAutoConfiguration @ComponentScan
public class InventoryApp {
   public static void main( String[] args ) {
      SpringApplication.run( InventoryApp.class, args );
   }
}

REST-контроллер:

package com.nice.controller; 
@RestController // shorthand for @Controller and @ResponseBody rolled together
public class ItemInventoryController {
   public ItemInventoryController() {
   }

   @RequestMapping( "/item" )
   public String getStockItem() {
      return "It's working...!";
   }

}

Я строю этот проект с помощью Maven. Запустил его как jar (spring-boot:run), а также внутри IDE (Eclipse).
