Контекстно-сканирование Spring MVC с несколькими сервлетами диспетчера с накладками maven

Question

Я создаю модульное веб-приложение с пружиной, используя наложения maven для объединения различных модулей в основное веб-приложение. Оба приложения являются стандартной структурой maven-archetype-webapp. Для тестирования я создал проект под названием «портал», который будет основной войной, и проект «привет», который будет наложен на главную войну. Основные файлы:

портал (основной) применение web.xml:

Aditionnally, у меня есть два контроллера тестирования. Один на модуле:

package pt.fhc.fmc.modules.hello; 
// Standard spring imports. 

@Controller 
public class HelloController { 

    @Autowired 
    TestService testService; 

    @RequestMapping(value = "/hello", method = RequestMethod.GET) 
    public ModelAndView home(Locale locale) { 

     ModelAndView model = new ModelAndView("helloview"); 
     return model; 
    } 
} 

И другие на главном проекте (портал):

package pt.fhc.fmc.web.controllers; 

@Controller 
public class HomeController { 
    @RequestMapping(value = "/", method = RequestMethod.GET) 
    public ModelAndView home(Locale locale) { 

     ModelAndView model = new ModelAndView("home"); 
     return model; 
    } 
} 

Основного pom.xml (на портале)

<dependencies> 
     <dependency> 
      <groupId>pt.fhc.fmc</groupId> 
      <artifactId>portal.services</artifactId>

Проблемы , во время сканирования контекста не обнаруживаются никакие контроллеры. что может отсутствовать?

Я использую Widfly 9.0.2 и Spring 4.2

Answer 1

В конце концов, эта проблема была решена с помощью переустановки WildFly. Конфигурация выше работает для нескольких диспетчерских сервлетов, в которых maven объединяет несколько веб-проектов в единую развертываемую войну.
