在Spring 5.1和Hibernate 5.3中，JPA EntityManagerHolder不能强制转换为Hibernate SessionHolder

Question

在我们的项目中，我们使用了Spring Boot 2.1.3、Spring Data Rest 3.1.5、Spring Data JPA 2.1.5和Hibernate 5.3.7，我们使用了Spring Framework 5.1和Hibernate 5.3的更改提供的一些新的可能性，即这一个和这一个。此外，我们将Spring Data JPA与Spring Data Rest存储库一起使用。

我们正在将Spring管理的服务注入到EntityListener中，当我们将LocalSessionFactoryBean用作EntityManagerFactory时，该EntityListener可以完美无缺地工作：

@Configuration
@EnableJpaRepositories(
        basePackages = "com.example.repository",
        bootstrapMode = BootstrapMode.DEFERRED,
        entityManagerFactoryRef = "sessionFactory",
        transactionManagerRef = "hibernateTransactionManager"
)
@EnableTransactionManagement
@Profile({ "local", "dev", "prod" })
public class DatabaseConfig
{
    @Bean
    public LocalSessionFactoryBean sessionFactory(
            final DataSource dataSource
    )
    {
        final LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

        sessionFactory.setDataSource(dataSource);
        sessionFactory.setPackagesToScan("com.example.model");

        return sessionFactory;
    }

    @Bean
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation()
    {
        return new PersistenceExceptionTranslationPostProcessor();
    }

    @Bean
    public HibernateTransactionManager hibernateTransactionManager(
            final SessionFactory sessionFactory,
            final DataSource dataSource
    )
    {
        final HibernateTransactionManager transactionManager = new HibernateTransactionManager();

        transactionManager.setSessionFactory(sessionFactory);
        transactionManager.setDataSource(dataSource);

        return transactionManager;
    }
}

但一旦我们收到第一个从存储库获取数据的HTTP请求,我们就会得到这个ClassCastException：

        collectionResourceRel = "results",
        itemResourceRel = "result"
)
public interface ResultRepository extends JpaRepository<Result, Long>

spring.jpa.open-in-view=false和HibernateTransactionManager已配置。

Answer 1

正如M.Deinum在第一条评论中所说的，解决方案是删除HibernateTransactionManager并使用Spring自动提供的。

此外，禁用spring.jpa.open-in-view可能是个好主意，因为它会急切地获取EntityManager。
