Question

我能够像这样创建一个sessionfactory bean。

@Configuration
public class HibernateConfig {

    private EntityManagerFactory emf;

    @Bean
    public HibernateJpaSessionFactoryBean sessionFactory() {
        HibernateJpaSessionFactoryBean fact = new HibernateJpaSessionFactoryBean();
        fact.setEntityManagerFactory(emf);
        return fact;
    }  

    @Autowired
    public HibernateConfig(EntityManagerFactory emf) {
        this.emf = emf;
    }

}

但是使用@ImportResource或@EntityScan与jar的类路径或列出hbm.xml文件仍会产生not a managed type: class com.opensymphony.workflow.spi.hibernate.HibernateCurrentStep

我看到一些答案，你使用另一个类来生成sessionFactory bean。是否有一种简单的方法可以在实体管理器创建中包含映射文件？

我能够用

扫描hbm.xml文件

 @Bean 
 public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) {
     LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
     em.setDataSource(dataSource);
     em.setPackagesToScan("com.foo.bar.domain");

     em.setMappingResources("classpath:x/HibernateCurrentStep.hbm.xml",
    "classpath:x/HibernateHistoryStep.hbm.xml",
    "classpath:x/HibernateWorkflowEntry.hbm.xml");

    HibernateJpaVendorAdapter vendor = new HibernateJpaVendorAdapter();
    vendor.setShowSql(false);
    em.setJpaVendorAdapter(vendor);
    return em;
}

但是使用会话工厂的任何事务都会获得No CurrentSessionContext configured!，而基本的spring repo方法仍然有效。

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) {
  LocalContainerEntityManagerFactoryBean em = new 
  LocalContainerEntityManagerFactoryBean();
  em.setDataSource(dataSource);
  em.setPackagesToScan("com.foo.bar.domain");

  em.setMappingResources("com/opensymphony/workflow/spi/hibernate3/HibernateCurrentStep.hbm.xml",
     "com/opensymphony/workflow/spi/hibernate3/HibernateHistoryStep.hbm.xml",
     "com/opensymphony/workflow/spi/hibernate3/HibernateWorkflowEntry.hbm.xml"); 
  //these needed to be added to have all hibernate config done in one place. 
 em.getJpaPropertyMap().put(AvailableSettings.CURRENT_SESSION_CONTEXT_CLASS, 
      SpringSessionContext.class.getName());
 em.getJpaPropertyMap().put(AvailableSettings.DIALECT,
      PostgreSQL9Dialect.class.getName());

  HibernateJpaVendorAdapter vendor = new HibernateJpaVendorAdapter();
  vendor.setShowSql(false);
  em.setJpaVendorAdapter(vendor);
  return em;
}

Spring Boot + Hibernate包含来自依赖jar的hbm.xml
