Question

我对Spring @Configuration类有一个奇怪的问题：其中定义的bean之一将找不到它的依赖项。

以下是@Configuration类：

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class MethodSecurityConfiguration extends GlobalMethodSecurityConfiguration {

    @Override
    protected AuthenticationManager authenticationManager() {
        AuthenticationManager authenticationManager = new ProviderManager();
        return authenticationManager;
    }

    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        DefaultMethodSecurityExpressionHandler expressionHandler = new DefaultMethodSecurityExpressionHandler();
        expressionHandler.setPermissionEvaluator(permissionEvaluator());
        return expressionHandler;
    }

    @Bean
    public ApplicationPermissionEvaluator permissionEvaluator() {
        return new ApplicationPermissionEvaluator(permissionMap());
    }

    private Map<String, Permission> permissionMap() {
        Map<String, Permission> map = new HashMap<>();
        map.put("updateAdvertisementIsAllowed", advertisementOwnerPermission());
        map.put("advertisementByIdOwnerPermission", advertisementByIdOwnerPermission());

        return map;
    }

    @Bean
    public AdvertisementOwnerPermission advertisementOwnerPermission() {
        return new AdvertisementOwnerPermission();
    }

    @Bean
    public AdvertisementByIdOwnerPermission advertisementByIdOwnerPermission() {
        return new AdvertisementByIdOwnerPermission();
    }


}

这是AdvertisementByIdOwnerPermission bean：

@Component
public class AdvertisementByIdOwnerPermission implements Permission {

    @Autowired
    private AdvertisementRepository advertisementRepository;
...

这是stacktrace：

我无法弄清楚为什么Spring无法找到AdvertisementRepository中定义的AdvertisementByIdOwnerPermission，而应用程序的其余部分正确选择它...

有人可以帮忙吗？

编辑1 ：有关我的Spring Data Jpa用法的信息：

Spring Data Jpa配置：

@Configuration
@EnableJpaRepositories(basePackages = "com.bignibou.repository")
public class JpaConfiguration {

}

存储库接口：

@RooJpaRepository(domainType = Advertisement.class)
public interface AdvertisementRepository {

}

编辑2 ：我认为这可能与我的配置类的初始化顺序有关。我尝试将@Order(Ordered.LOWEST_PRECEDENCE + 10)添加到我的MethodSecurityConfiguration类中，但它仍然不起作用。

我根据Oliver Gierke的建议使用最新版本的Spring Data Commons和Spring Data JPA对此问题进行了排序：https://stackoverflow.com/a/23347954/536299

这实际上是我使用的Spring Data版本中的一个小错误。

@Configuration类在初始化期间无法使用JPA存储库导致NoSuchBeanDefinitionException
