在自定義身份驗證提供程序（Spring Security 3.2）中使用服務層

Question

我不明白爲什麼我無法在身份驗證提供程序（文件：userDetailsS​​ervice）中使用服務層（文件：用戶服務）。結果我有下面的錯誤，但是當我使用存儲庫層（文件：庫）一切都很好。

我想封裝存儲庫層（Spring數據Jpa）並且只使用Service層來滿足所有需求。爲什麼在這種情況下不可能？

的UserDetailsS​​ervice

@Service 
public class AuthServiceImpl implements UserDetailsService { 

    private final Logger log = LoggerFactory.getLogger(getClass()); 
    @Autowired 
    User_service user_service; 

    @Transactional 
    @Override 
    public UserDetails loadUserByUsername(String username) 
      throws UsernameNotFoundException { 
     log.trace("START-------------------------------------"); 
     Signup details = user_service.findByLogin(username); 
     log.trace(details.getLogin()+"---------------------"+details.getPassword()); 
     Collection<SimpleGrantedAuthority> authorities = new ArrayList<SimpleGrantedAuthority>(); 
     SimpleGrantedAuthority userAuthority = new SimpleGrantedAuthority(
       "ROLE_USER"); 
     SimpleGrantedAuthority adminAuthority = new SimpleGrantedAuthority(
       "ROLE_ADMIN"); 
     if (details.getRole() == 1) 
      authorities.add(userAuthority); 
     else if (details.getRole() == 2) { 
      authorities.add(userAuthority); 
      authorities.add(adminAuthority); 
     } 
     UserDetails user = new User(details.getLogin(), 
       details.getPassword(), true, true, true, true, authorities); 
     return user; 
    }

Answer 1

的問題是，春天沒有User_service豆的知識。

User_service bean未在您的上下文配置中聲明既不啓用組件註釋類的類路徑掃描。 （給你貼的配置）

嘗試用下面的XML聲明打開組件掃描（可能定義型屬性：

<context:component-scan base-package="your.package" /> 

或上下文配置聲明中bean

希望這有助於！
