Spring 기반 프로젝트에서 Controller 에 매핑시킨 URL 리스트를 불러오는 예제.

          map.put("ID", beanName.replace("Controller", ""));
          map.put("URL", url);
          mappingInfoList.add(map);
        }
      }
    }
    
    return mappingInfoList;
  }
  
}

 

프로젝트에서 컨트롤러의 이름을 프로그램IDController 라고 지정한다는 가정하에 ID를 지정한다.
