java - Hibernate sessionFactory 的编程配置导致 'sessionFactory' 或 'hibernateTemplate' 是必需的

Question

我正在关注 spring doc entry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。

主要内容:

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());
    }
}

session 配置:

@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();
    }
}

报告配置:

@Configuration
public class ReportConfig {

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

报告道:

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:

我原以为 SessionConfig Bean 会满足 sessionFactory 要求，但也许我误解了它的工作原理。

将 ReportConfig 更改为:

@Configuration
public class ReportConfig {  

    @Autowired
    private SessionFactory sessionFactory;

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