최대 절전 모드 관련 객체가 수화되지 않음

Question

아래 코드를 참조하십시오. DeviceDAO, Device 및 Mobileuser는 최대 절전 모드로 생성 된 개체입니다. 이 프로세스는 내가 mobileUser.getPin()을 호출하는 두 번째 "if"조건에 도달 할 때까지 작동합니다. 문제는 모바일 사용자의 속성 (예 : 핀)이 null이라는 것입니다. 값은 DB에 있지만 null 영역이므로 내 호출은 null 포인터 예외를 발생시킵니다. 모바일 사용자의 속성은 최대 절전 모드로 수분을 공급받지 못했습니다. 어떤 도움을 주셔서 감사합니다. 감사. 요청에 따라

DeviceDAO deviceDao = new DeviceDAO(); 
    List<Device> devices = deviceDao.findByUdid(requestTokenModel.getUdid()); 

       if(!devices.isEmpty()) 
      { 
       Device device = devices.get(0); 
       Mobileuser mobileUser =device.getMobileuser(); 
       if(mobileUser.getPin().contentEquals(requestTokenModel.getPiin()) && mobileUser.getIsactive() == "Y") 
         { 
          //omitted      
         } 
      } 

UPDATE

는 여기에 몇 가지 추가 정보입니다 : 내가 생성 된 데이터 객체와 DAO 객체은 MyEclipse 최대 절전 모드 리버스 엔지니어링을 사용하고

당신의 Mobileuser 클래스는 방법 getPin있는 동안

Answer 1

내가 이런 일이 생기면 두려워하지만 점심 식사에서 돌아 왔고 이제는 제대로 작동합니다. 이전에는 변경하지 않았지만 지금은 만족합니다. 무슨 일이 일어나고 있는지 전혀 몰랐습니다.

감사합니다. 디버깅 도움말 @Corey.

Answer 2

Mobileuser.hbm은) ("접합 piin"라는 이름의 속성이 있습니다 . 이 중 하나가 오타 일 수 있습니까? 그들은 동일한 정보를 나타 내기위한 것이라는 가정하에 일치해야합니다. setter, setPin (String) 또는 setPiin (String) 중 어느 것이어야한다.

db에 "piin"열이있는 경우 나중에 db에서 매핑을 재생성 할 수 없지만 속성 핀을 piin 열에 매핑하도록 매핑을 변경할 수 있습니다.
