Hibernate sessionFactory的程序化配置需要“ sessionFactory”或“ hibernateTemplate”

我关注关于在独立应用程序中以编程方式设置我的应用程序上下文的spring doc条目。

主要的：

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);
    }
}

结果：

我期望SessionConfig Bean可以满足sessionFactory的要求，但是也许我误解了它的工作原理。

更改ReportConfig为：

@Configuration
public class ReportConfig {  

    @Autowired
    private SessionFactory sessionFactory;

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