Spring 自定义UserDetails服务未正确执行

我正在尝试配置Spring安全性，但我的自定义UserDetailsService有一个额外的问题。每次尝试登录时，我都会被重定向到失败页面。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;
    }

}

正如您在代码中所看到的，一些记录器从未打印过，这有点奇怪

以下是我的用户模型、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);
    }
}

@实体
公共类用户实现UserDetails{
//更多代码
@事务（只读=真）
公共接口用户存储库扩展了JpaRepository{
用户findByUsername（字符串用户名）；
}
@存储库
@事务（只读=真）
公共类UserServiceImpl实现UserService{
@自动连线
私有用户存储库用户存储库；
@凌驾
公共列表findAll（）{
返回userRepository.findAll（）；
}
@凌驾
公共用户findOne（字符串用户名）{
返回userRepository.findByUsername（用户名）；
}
@凌驾
@交易的
公共用户保存（用户）{
返回userRepository.save（用户）；
}
}

最后，我前面运行的添加测试用户的代码：

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);

User User=新用户（）；
user.setPassword（“7c4a8d09ca3762af61e59520943dc26494f8941b”）；/123456
user.setUsername（“davidmogar”）；
Set grantedAuthories=new HashSet（）；
添加（新的SimpleGrantedAuthority（“角色管理”）；
user.setGrantedAuthories（GrantedAuthories）；
userService.save（用户）；

我做错了什么

编辑

由于未知原因，userService为空，因此未自动连接。我不确定是哪一个问题。此服务在控制器内运行良好。

将

autowire=“byType”

添加到userDetailsService bean的xlm定义中

---

并从类中删除服务注释，否则将有两个实例。

我没有UserDetails服务bean定义。关于服务注释，我使用它加载服务，但由于未知原因，它无法工作，我必须添加bean定义。当我删除bean声明时，我得到以下错误：“未定义名为‘customUserDetailsService’的bean”我如何解决此问题？它在您的安全性中。XML！尝试创建一个将用户服务作为参数的构造函数。除了将@Auto-wire添加到此构造函数之外，请删除所有其他注释。在XML中使用Auto-wire，=”构造函数"如果您使用@Service etc，则需要启用组件扫描，否则Spring将无法定位和实例化该bean。请将其视为使用定义的快捷方式。@David Moreno Garcia:Jukka的解释是正确的。通常，通过组件扫描找到的bean由其none argumemt构造函数固定；如果您希望t要使用其他构造函数，请在此构造函数处放置

@Autowire

注释。
