Hibernate sessionFactory的程序化配置需要'sessionFactory'或'hibernateTemplate'

Question

我正在關注spring doc entry在獨立應用程序中以編程方式設置我的應用程序上下文。

主要：

public class Reporter { 

    public static void main(String[] args) { 
     AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(SessionConfig.class, ReportConfig.class); 
     ReportDao reportDao = ctx.getBean(ReportDao.class); 
     Report report = reportDao.getReport("an_id"); 
     System.out.println(report.getReportName()); 
    } 
} 

SessionConfig：

@Configuration 
public class SessionConfig { 

    @Bean 
    public HibernateTransactionManager getTransationManager() { 
     return new HibernateTransactionManager(getSessionFactory()); 
    } 

    @Bean 
    public SessionFactory getSessionFactory() { 
     LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(new MyDataSource()); 
     builder.addAnnotatedClass(Report.class); 
     builder.scanPackages("com.mystuff.dao"); 
     Properties hibernateProperties = new Properties(); 
     hibernateProperties.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect"); 
     hibernateProperties.put("hibernate.connection.provider_class", "com.mystuff.dao.MyConnectionProvider"); 
     builder.addProperties(hibernateProperties); 
     return builder.buildSessionFactory(); 
    } 
} 

ReportConfig：

@Configuration 
public class ReportConfig { 

    @Bean 
    public ReportDao reportDao(){ 
     return new ReportDaoImpl(); 
    } 
} 

ReportDao：

public interface ReportDao { 
    /** Add or update the given report. */ 
    void updateReport(Report report); 
    /** @return all reports. */ 
    List<Report> getReports(); 
    /** @return report for the given identifier */ 
    Report getReport(String id); 
} 

ReportDaoImpl：

@Repository 
public class ReportDaoImpl extends HibernateDaoSupport implements ReportDao { 
    @Override 
    public void updateReport(Report report) { 
     getHibernateTemplate().saveOrUpdate(report); 
    } 

    @Override 
    public List<Report> getReports() { 
     return (List<Report>)getHibernateTemplate().find("from Report"); 
    } 

    @Override 
    public Report getReport(String id) { 
     return (Report) getHibernateTemplate().get(Report.class, id); 
    } 
} 

結果：

我期待通過SessionConfig豆滿足SessionFactory的要求，但也許我誤解是如何工作的。

更改ReportConfig到：

@Configuration 
public class ReportConfig { 

    @Autowired 
    private SessionFactory sessionFactory; 

    @Bean 
    public ReportDao reportDao(){ 
     final ReportDaoImpl reportDao = new ReportDaoImpl(); 
     reportDao.setSessionFactory(sessionFactory); 
     return reportDao; 
    } 
}
