Question

我正在尝试配置Spring Security，但我的自定义UserDetailsService存在一个问题。每当我尝试登录时，我都会被重定向到我的失败页面。这是服务的代码：

@Service("customUserDetailsService")
public class CustomUserDetailsService implements UserDetailsService {

    private static final Logger logger = LoggerFactory.getLogger(CustomUserDetailsService.class);

    @Autowired
    private UserService userService;

    @Override
    public UserDetails loadUserByUsername(String username)
        throws UsernameNotFoundException {

        logger.info("This is printed");

        UserDetails userDetails = userService.findOne(username);

        logger.info("This isn't printed");

        if (userDetails == null) {
            logger.info("This isn't printed");
            throw new UsernameNotFoundException("No user found with username "
                    + username);
        }

        return userDetails;
    }

}

正如您在代码中看到的那样，一些记录器从未打印过，这有点奇怪......

这是我的用户模型，其存储库及其服务类：

@Entity
public class User implements UserDetails {
    // more code


@Transactional(readOnly = true)
public interface UserRepository extends JpaRepository<User, Long> {

    User findByUsername(String username);
}

@Repository
@Transactional(readOnly = true)
public class UserServiceImpl implements UserService {

    @Autowired
    private UserRepository userRepository;

    @Override
    public List<User> findAll() {
        return userRepository.findAll();
    }

    @Override
    public User findOne(String username) {
        return userRepository.findByUsername(username);
    }

    @Override
    @Transactional
    public User save(User user) {
        return userRepository.save(user);
    }
}

最后，我之前运行的代码是为了添加测试用户：

User user = new User();
user.setPassword("7c4a8d09ca3762af61e59520943dc26494f8941b"); // 123456
user.setUsername("davidmogar");
Set<GrantedAuthority> grantedAuthorities = new HashSet<GrantedAuthority>();
grantedAuthorities.add(new SimpleGrantedAuthority("ROLE_ADMIN"));
user.setGrantedAuthorities(grantedAuthorities);
userService.save(user);

我做错了什么？

修改

由于未知原因，userService为null，因此未进行自动装配。我不确定哪个可能是问题所在。这项服务在控制器内部运行良好。

Answer 1

将autowire="byType"添加到userDetailsService bean的xlm定义

从类中删除服务注释，否则你将有两个实例。
