使用 Spring 5.1 和 Hibernate 5.3 无法将 JPA EntityManagerHolder 转换为 Hibernate SessionHolder
JPA EntityManagerHolder cannot be cast to Hibernate SessionHolder with Spring 5.1 and Hibernate 5.3
在我们的项目中，它使用 Spring Boot 2.1.3、Spring Data Rest 3.1.5、Spring Data JPA 2.1.5 和 Hibernate 5.3.7，我们是使用 Spring Framework 5.1 和 Hibernate 5.3 中的变化提供的一些新的可能性，即 this one and this one。此外，我们使用 Spring Data JPA 和 Spring Data Rest 存储库。
我们将 spring 管理的服务注入到 EntityListener 中，当我们将 LocalSessionFactoryBean 用作 entityManagerFactory:
时，它可以完美地工作
@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;
}
}
但是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:

spring.jpa.open-in-view=false 并且配置了 HibernateTransactionManager。
正如 M. Deinum 在第一条评论中所说，解决方案是删除 HibernateTransactionManager 并使用 Spring 自动提供的那个。
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.
在我们的项目中，它使用 Spring Boot 2.1.3、Spring Data Rest 3.1.5、Spring Data JPA 2.1.5 和 Hibernate 5.3.7，我们是使用 Spring Framework 5.1 和 Hibernate 5.3 中的变化提供的一些新的可能性，即 this one and this one。此外，我们使用 Spring Data JPA 和 Spring Data Rest 存储库。
我们将 spring 管理的服务注入到 EntityListener 中，当我们将 LocalSessionFactoryBean 用作 entityManagerFactory:
@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;
}
}
但是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:

spring.jpa.open-in-view=false 并且配置了 HibernateTransactionManager。

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.
