Question

我正在使用Hibernate 5.4.0.Final 和Spring 4.3.13.RELEASE 我写了以下代码

@Bean
    public SessionFactory sharedDataSessionFactory()
    {
        LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(sharedDataSource());
        builder.scanPackages("com.some.package", "scom.some.package1");
        hibernateProperties.put("hibernate.dialect", MySQL5InnoDBDialect.class);
        hibernateProperties.put("hibernate.id.new_generator_mappings", false);
        hibernateProperties.put("hibernate.show_sql", false);
        hibernateProperties.put("hibernate.cache.use_second_level_cache", false);
        hibernateProperties.put("hibernate.cache.use_query_cache", false);
        hibernateProperties.put("hibernate.jdbc.batch_size", 25);
        builder.addProperties(hibernateProperties);
        return builder.buildSessionFactory();
   }

   @Bean
   public PlatformTransactionManager transactionManagerSharedData() {
    return new HibernateTransactionManager(sharedDataSessionFactory());
  }

但是当我运行测试代码时，它会像这样给出异常

 Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.transaction.PlatformTransactionManager]: Factory method 'transactionManagerSharedData' threw exception; nested exception is java.lang.ClassCastException: org.springframework.orm.hibernate5.LocalSessionFactoryBean$$EnhancerBySpringCGLIB$$d6b39340 cannot be cast to org.hibernate.SessionFactory

但是我的应用程序运行正常。这个班的原因是什么？

无法将LocalSessionfactory转换为SessionFactory
