내 데이터베이스의 사용자를 스프링 보안 사용자에게 맵핑하려고하는데,별로 행운이 없다. 내 UserServiceImpl이 스프링 보안 널 포인터 예외
@Service("userService")
@Transactional
public class UserServiceImpl implements UserService, UserDetailsService {
protected static Logger logger = Logger.getLogger("service");
@Autowired
private UserDAO userDao;
public UserServiceImpl() {
}
@Transactional
public User getById(Long id) {
return userDao.getById(id);
}
@Transactional
public User getByUsername(String username) {
return userDao.getByUsername(username);
}
@Override
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException {
UserDetails user = null;
try {
System.out.println(username);
User dbUser = getByUsername(username);
user = new org.springframework.security.core.userdetails.User(
dbUser.getUsername(), dbUser.getPassword(), true, true,
true, true, getAuthorities(dbUser.getAccess()));
} catch (Exception e) {
e.printStackTrace();
logger.log(Level.FINE, "Error in retrieving user");
throw new UsernameNotFoundException("Error in retrieving user");
}
// Return user to Spring for processing.
// Take note we're not the one evaluating whether this user is
// authenticated or valid
// We just merely retrieve a user that matches the specified username
return user;
}
public Collection<GrantedAuthority> getAuthorities(Integer access) {
// Create a list of grants for this user
List<GrantedAuthority> authList = new ArrayList<GrantedAuthority>(2);
// All users are granted with ROLE_USER access
// Therefore this user gets a ROLE_USER by default
logger.log(Level.INFO, "User role selected");
authList.add(new GrantedAuthorityImpl("ROLE_USER"));
// Check if this user has admin access
// We interpret Integer(1) as an admin user
if (access.compareTo(1) == 0) {
// User has admin access
logger.log(Level.INFO, "Admin role selected");
authList.add(new GrantedAuthorityImpl("ROLE_ADMIN"));
}
// Return list of granted authorities
return authList;
}
}
나는 다음과 같은 예외를 얻을 ... 다음과 같이합니다 (autowiring을 정상적으로 내가 서블릿을 통해 호출있을 때 잘 작동하지만 봄 보안 사용할 때 널 포인터를 던졌습니다입니다 (첫 번째 줄 내 userDao가 제대로 autowiring에없는 것처럼입니다 System.out을)은

그래서 보이는,하지만 난 봄 - 보안을 사용하여 단지 분명히하지 않을 경우, 서블릿에서 서비스 레이어를 호출 할 때 그것을 잘 작동합니다.
라인 40은 return userDao.getByUsername (usern ame);
@autowired를 통해 userDao를 채우는 방법에 대한 아이디어가있는 사람이 있습니까? 내가 말했듯이 스프링 보안을 사용하려고 할 때가 아니라 서블릿을 통해 호출 할 때 제대로 작동합니다.
스프링 보안에서 사용자와 비밀번호를 쉽게 매핑 할 수 있습니까? 다음과 같이
내 보안 앱 컨텍스트가 ... 내 질문은 생각

이다, 왜 내 userDao @Autowired 봄 보안 작동하지 않습니다, 아직 사용할 때 그것을 잘 작동합니다 서블릿에서 사용자 객체를 반환하겠습니까? 예를 들어, 다음 서블릿이 잘 작동합니다 ...
스프링 보안을 통과 할 때 autowiring (NPE가 throw 됨)되어 작동하지 않는 이유는 무엇입니까? 서블릿에서 호출 할 때 제대로 작동하는 이유는 무엇입니까?
편집 : -
을 추가하지만 지금 당신은 빈 선언을 통해 서비스를 만드는 신경

이 내용을 컨텍스트 xml에 추가 할 수 있습니까? ' –
또한, 이미 \t을 가지고 있습니다. 내 서블릿 컨텍스트에서 두 XML 파일 모두에서 필요합니까? –
