java - 如何在 Spring 3 的 Java 配置中连接我的 Hibernate 4 拦截器？

Question

我有一个 Hibernate 拦截器，我想将其放在 Hibernate 的 onLoad() 调用上。我这样做是因为我希望 JPA 实体有一个由 Spring 注入(inject)的 SecureRandom 实例。由于 JPA 上下文和 Spring 上下文不混合，因此这是从 Spring 上下文到 JPA 上下文的桥梁。

我的 Java 配置中有“两个地方”，我在其中设置了 Hibernate 4 的内容。我在下面包含了它们的条目。根据此( https://jira.springsource.org/browse/SPR-8940 )，我认为要以编程方式设置 Hibernate 拦截器，我需要访问 LocalSessionFactoryBean。也许通过 LocalContainerEntityManagerFactoryBean？我只是不知道该怎么做，或者是否需要重新配置我设置 Hibernate 内容的方式。任何帮助将不胜感激!

@Bean
JpaTransactionManager jpaTransactionManager(LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean) {
    JpaTransactionManager jpaTransactionManager = new JpaTransactionManager();
    jpaTransactionManager.setEntityManagerFactory(localContainerEntityManagerFactoryBean.getObject());
    return jpaTransactionManager;
}

@Bean(name = "LocalContainerEntityManagerFactory")
@Autowired
public LocalContainerEntityManagerFactoryBean entityManagerFactory(BasicDataSource jdbcConnection) throws ClassNotFoundException, IllegalAccessException, InstantiationException {
    Class.forName("com.mysql.jdbc.Driver").newInstance();
    LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
    localContainerEntityManagerFactoryBean.setDataSource(jdbcConnection);
    localContainerEntityManagerFactoryBean.setPackagesToScan(this.getClass().getPackage().getName());

    Properties jpaProperties = new Properties();
    jpaProperties.setProperty("hibernate.hbm2ddl.auto", "create");
    localContainerEntityManagerFactoryBean.setJpaProperties(jpaProperties);
    HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
    hibernateJpaVendorAdapter.setDatabasePlatform("org.hibernate.dialect.MySQL5InnoDBDialect");
    hibernateJpaVendorAdapter.setShowSql(true);
    localContainerEntityManagerFactoryBean.setJpaVendorAdapter(hibernateJpaVendorAdapter);
    return localContainerEntityManagerFactoryBean;
}


@Component
public class InvitationEntityInterceptor extends EmptyInterceptor {
    @Autowired
    SecureRandom secureRandom;
    @Override
    public boolean onLoad(Object entity, Serializable id, Object[] state, String[] propertyNames, Type[] types) {
        if(entity instanceof Invitation) {
            Invitation invitation = (Invitation) entity;
            invitation.setRandom(secureRandom);
        }
        return false;
    }
}

我是这样处理的:

Spring数据库配置类:

@Bean
@DependsOn("hibernateInterceptor")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(
        DataSource dataSource,
        JpaVendorAdapter jpaVendorAdapter,
        HibernateInterceptor hibernateInterceptor) {

    LocalContainerEntityManagerFactoryBean emfb =
            new LocalContainerEntityManagerFactoryBean();
    ...
    Properties props = new Properties();
    props.put("hibernate.ejb.interceptor", hibernateInterceptor);
    emfb.setJpaProperties(props);
    return emfb;
}

Hibernate拦截器类:

@Component
public class HibernateInterceptor extends EmptyInterceptor {
    ...
    @Autowired
    private MyRepository myRepository;
    ...
}
