Java 일반 T.class 가져오기

public interface BaseDao<T> {  
    T get(String id);  
}

13     public HibernateBaseDao() {  
14         Type genType = getClass().getGenericSuperclass();  
15         Type[] params = ((ParameterizedType) genType).getActualTypeArguments();  
16         entityClass = (Class) params[0];  
17     }

19     @Override  
20     public T get(String id) {  
21         try {  
22             return entityClass.newInstance();  
23         } catch (InstantiationException e) {  
24             // TODO Auto-generated catch block  
25             e.printStackTrace();  
26         } catch (IllegalAccessException e) {  
27             // TODO Auto-generated catch block  
28             e.printStackTrace();  
29         }  
30         return null;  
31     }  
32   
33 }  

14-16 줄이 포인트, entity Class는 Class, 즉 T.class입니다.
