Я продолжаю получать ошибку ConflictingBeanDefinitionException в моем загрузочном приложении Spring. Я не совсем уверен, как это сделать, у меня есть несколько аннотированных классов @Configuration, помогающих настроить Thymeleaf, Spring Security и Web. Почему приложение пытается настроить homeController дважды? (и где он пытается это сделать?)
Ошибка:
org.springframework.beans.factory.BeanDefinitionStoreException:
Failed to parse configuration class [org.kemri.wellcome.hie.Application]; nested exception is org.springframework.context.annotation.ConflictingBeanDefinitionException:
Annotation-specified bean name 'homeController' for bean class [org.kemri.wellcome.hie.HomeController] conflicts with existing, non-compatible bean definition of same name and class [org.kemri.wellcome.hie.controller.HomeController]

Мой контроллер (где есть ошибка настройки контроллера)
@Controller
public class HomeController {
private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
/**
* Simply selects the home view to render by returning its name.
*/
@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
logger.info("Welcome home! The client locale is {}.", locale);
Date date = new Date();
DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
String formattedDate = dateFormat.format(date);
model.addAttribute("serverTime", formattedDate );
return "index.html";
}
}
Что может вызвать ошибку ConflictingBeanDefinitionException для моего класса контроллера?
