クラス<T>を豆としてどのように注入するのですか？

Question

私はリポジトリとして以下のクラスUserAuthorityRepositoryあります

@Repository 
public class UserAuthorityRepository extends BaseRepository<UserAuthority, Long> implements IUserAuthorityRepository { 

public UserAuthorityRepository(Class<UserAuthority> domainClass, EntityManager em) { 
    super(domainClass, em); 
} 

} 

そしてUserAuthorityServiceに私が持っている：

@Service 
public class UserAuthorityService extends BaseService<UserAuthority, Long> implements IUserAuthorityService { 

private static final Logger LOGGER = LoggerFactory.getLogger(UserAuthorityService.class); 

@Autowired 
private IUserAuthorityRepository userAuthorityRepo; 

public UserAuthorityService() { 
    super(); 
    LOGGER.info("UserAuthorityService Has Been Created"); 
} 

@Bean 
@Override 
public Class<UserAuthority> getDomain() { 
    return UserAuthority.class; 
} 

@Override 
public IBaseRepository<UserAuthority, Long> getRepository() { 
    return userAuthorityRepo; 
} 

} 

をしかし、私のアプリケーションは、次のように起動時に例外を取得します。

Description: 

Parameter 0 of constructor in com.bia2hd.dao.impl.UserAuthorityRepository required a bean of type 'java.lang.Class' that could not be found. 


Action: 

Consider defining a bean of type 'java.lang.Class' in your configuration.

私はちょうどそれを解決しました（それほど満足ではありませんが、働いています）。

@Configuration 
public class Beans { 

    @Autowired 
    private ApplicationContext applicationContext; 

    @PostConstruct 
    public void createClassBeans() throws ClassNotFoundException { 

     ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(false); 

     scanner.addIncludeFilter(new AnnotationTypeFilter(Entity.class)); 

     ConfigurableListableBeanFactory beanFactory = ((ConfigurableApplicationContext) applicationContext) 
      .getBeanFactory(); 

     for (BeanDefinition bd : scanner.findCandidateComponents("my.package")) { 
     Class<?> bean = Class.forName(bd.getBeanClassName()); 
     beanFactory.registerSingleton(bean.getName(), bean); 
     } 

    } 

} 

そして

@Repository 
public class UserRepository extends BaseRepository<User, Long> implements IUserRepository { 

    UserRepository(@Qualifier("my.package.User") Class<User> domainClass, EntityManager em) { 
     super(domainClass, em); 
    } 

}
