向启动时加载的@Configuration类使用的bean本身注入依赖项的问题

Question

我希望@Configuration类操作Spring bean的Map（这里的bean将是Map的值）。

此外，一些Spring bean会将依赖注入其中 - 例如Spring Data Jpa存储库。

我有以下配置类（MethodSecurityConfiguration）：

@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();
    }

}

这将是上述Map（AdvertisementByIdOwnerPermission）的值：

@Component
public class AdvertisementByIdOwnerPermission implements Permission {

    @Autowired
    private AdvertisementRepository advertisementRepository;

    @Override
    public boolean isAllowed(Authentication authentication, Object targetDomainObject) {
        boolean hasPermission = false;

        if (isId(targetDomainObject)) {
            Advertisement advertisement = advertisementRepository.findOne((Long) targetDomainObject);
            if (advertisement.getMember().getId().equals(((Member) authentication).getId())) {
                hasPermission = true;
            }
        }
        return hasPermission;
    }

    private boolean isId(Object targetDomainObject) {
        return targetDomainObject instanceof Long && (Long) targetDomainObject > 0;
    }

}

以下是我在应用程序上下文启动时遇到的异常：

任何人都可以帮我配置我的应用程序，以便AdvertisementByIdOwnerPermission正确地注入其依赖项吗？

编辑1 ：AdvertisementRepository是一个Spring数据Jpa存储库，声明如下：

RooJpaRepository：

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

}

与ITD一起：

privileged aspect AdvertisementRepository_Roo_Jpa_Repository {

    declare parents: AdvertisementRepository extends JpaRepository<Advertisement, Long>;

    declare parents: AdvertisementRepository extends JpaSpecificationExecutor<Advertisement>;

    declare @type: AdvertisementRepository: @Repository;

}

编辑2 ：JPA配置：

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

}

public abstract class DataConfiguration {

    @Value("${database.driverClassName}")
    private String driverClassName;

    @Value("${database.url}")
    private String url;

    @Value("${database.username}")
    private String username;

    @Value("${database.password}")
    private String password;

    @Value("${database.validationQuery}")
    private String validationQuery;

    @Bean(destroyMethod = "close")
    public DataSource dataSource() {
        BasicDataSource dataSource = new BasicDataSource();
        dataSource.setDriverClassName(driverClassName);
        dataSource.setUrl(url);
        dataSource.setUsername(username);
        dataSource.setPassword(password);
        dataSource.setTestOnBorrow(Boolean.TRUE);
        dataSource.setTestOnReturn(Boolean.TRUE);
        dataSource.setTestWhileIdle(Boolean.TRUE);
        dataSource.setTimeBetweenEvictionRunsMillis(1800000);
        dataSource.setNumTestsPerEvictionRun(3);
        dataSource.setMinEvictableIdleTimeMillis(1800000);
        dataSource.setValidationQuery(validationQuery);
        dataSource.setMaxActive(5);
        dataSource.setLogAbandoned(Boolean.TRUE);
        dataSource.setRemoveAbandoned(Boolean.TRUE);
        dataSource.setRemoveAbandonedTimeout(10);
        return dataSource;
    }

    @Bean
    public JpaTransactionManager transactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
        return transactionManager;
    }

    @Bean
    public EntityManager entityManager() {
        return entityManagerFactory().getObject().createEntityManager();
    }

    @Bean
    public HibernateJpaVendorAdapter jpaVendorAdapter() {
        return new HibernateJpaVendorAdapter();
    }

    @Bean
    public HibernatePersistence persistenceProvider() {
        return new HibernatePersistence();
    }

    @Bean(name = "entityManagerFactory")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactoryBean.setPackagesToScan("com.bignibou.domain");
        entityManagerFactoryBean.setDataSource(dataSource());
        entityManagerFactoryBean.setPersistenceProvider(persistenceProvider());
        entityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter());
        entityManagerFactoryBean.setJpaPropertyMap(propertiesMap());
        entityManagerFactoryBean.afterPropertiesSet();
        return entityManagerFactoryBean;
    }

    public abstract Map<String, String> propertiesMap();

    @Bean
    public HibernateExceptionTranslator hibernateExceptionTranslator() {
        return new HibernateExceptionTranslator();
    }

}

@Profile({ Profiles.DEFAULT, Profiles.CLOUD, Profiles.DEV })
@Configuration
@EnableTransactionManagement(mode = AdviceMode.ASPECTJ)
class DefaultDataConfiguration extends DataConfiguration {

    @Override
    public Map<String, String> propertiesMap() {
        Map<String, String> propertiesMap = new HashMap<>();
        propertiesMap.put("hibernate.dialect", "org.hibernate.dialect.MySQL5InnoDBDialect");
        propertiesMap.put("hibernate.hbm2ddl.auto", "update");
        propertiesMap.put("hibernate.ejb.naming_strategy", "org.hibernate.cfg.ImprovedNamingStrategy");
        propertiesMap.put("hibernate.connection.charSet", "UTF-8");
        propertiesMap.put("hibernate.show_sql", "true");
        propertiesMap.put("hibernate.format_sql", "true");
        propertiesMap.put("hibernate.use_sql_comments", "true");
        return propertiesMap;
    }

}

编辑3 ：我按如下方式更改了MethodSecurityConfiguration：

@Autowired//FAILS!!
private AdvertisementRepository advertisementRepository;

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

现在AdvertisementByIdOwnerPermission通过构造函数获取其依赖关系。要解决的唯一问题是AdvertisementRepository类在尝试自动装配时尚未构造MethodSecurityConfiguration。有人可以帮我解决这个问题吗？

编辑4 ：我尝试将@Order(2)放入MethodSecurityConfiguration类，将@Order(1)放入JpaConfiguration类。我还有同样的问题...

编辑5 ：使用@ComponentScan注释的@Configuration类：

@Configuration
@EnableSpringConfigured
@ComponentScan(basePackages = { "com.bignibou" }, excludeFilters = { @Filter(type = FilterType.CUSTOM, value = RooRegexFilter.class),
        @Filter(type = FilterType.ANNOTATION, value = Controller.class) })
public class BaseConfiguration {
...

Answer 1

这很可能是由于使用旧版本的Spring Data JPA引起的。当使用1.4.2时，你应该引入Spring Data Commons 1.7.2，这样我们在类型预测方面做了一些改进。

底线是：这应该在最新版本中使用。
