Autowired @Service는 null이 아닙니다.

Question

그 문제로 수십억의 질문을 알고 있지만 문제를 해결할 수 없습니다. 나는 봄 + 최대 절전 모드로 애플 리케이션을 가지고. Hibernate는 2 개의 설정 (고객 및 관리 데이터베이스 용)을 가지고있다. 고객의 최대 절전 모드는 DATABASE 방식으로 멀티 테넌시를 지원합니다. 또한 스프링 보안을 사용합니다.
이 세입자 아이디 해결을위한 내 수업은 다음과 같습니다

@Component 
public class MyTenantIdentifierResolver implements CurrentTenantIdentifierResolver { 

    @Autowired 
    private UserService userService; 

    public String resolveCurrentTenantIdentifier() { 
     User u = (User) SecurityContextHolder.getContext().getAuthentication().getPrincipal(); 
     com.lspsystem.model.User us = userService.getByLogin(u.getUsername()); 
     return us.getCompany().getTenantId(); 
    } 

    public boolean validateExistingCurrentSessions() { 
     return true; 
    } 
} 

그것은 내 UserService입니다 :

@Service 
public class UserServiceImpl implements UserService { 

    @Autowired 
    private UserDAO userDAO; 

    public User get(Integer id) { 
     return userDAO.get(id); 
    } 

    public boolean delete(Integer id) { 
     return userDAO.delete(id); 
    } 

    public void update(User u) { 
     userDAO.update(u); 
    } 

    public List<User> getAll(User u) { 
     return userDAO.getAllUsers(); 
    } 

    public User getByLogin(String login) { 
     return userDAO.getByLogin(login); 
    } 
} 

내 질문 : MyTenantIdResolver에 UserService 항상 null 왜? 그러나 예를 들어 다음 학급 (보안)에서는 null이 아닙니다. UserService 및 MyTenantIdResolver 다른 최대 절전 CONFIGS에 속하는

@Service 
public class UserDetailsServiceImpl implements UserDetailsService { 

    @Autowired 
    private UserService userService; 

    public User loadUserByUsername(String s) throws UsernameNotFoundException { 
     com.lspsystem.model.User u = userService.getByLogin(s); 
     return new User(u.getEmail(), u.getPassword(), true, true, true, true, getGrantedAuthorities(u)); 
    } 

    @Autowired 
    public UserDetailsServiceImpl(UserService userService) { 
     this.userService = userService; 
    } 

    private List<GrantedAuthority> getGrantedAuthorities(com.lspsystem.model.User u) { 
     List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>(); 
     return authorities; 
    } 
} 

참고.

사실 일 수는 없습니다. @Autowire은 필드가 널이 아니도록합니다. 따라서 userService=null을 갖는 유일한 경우는 MyTenantIdentifierResolver이 스프링 빈이 아닐 때입니다!

MyTenantIdentifierResolver의 인스턴스를 spring-bean으로 설정하십시오.
