我有一个使用Spring3和Hibernate4的Web项目，现在我想在不使用xml文件的情况下测试DAO。为此，我创建了一个类，该类使用应用程序的xml文件中包含的数据和一个简单的测试类创建一个LocalSessionFactoryBean。

但是， localSessionFactoryBean.getObject（） 返回的 sessionFactory
为null。我一直在寻找像一些例子这和他们有同样的问题，当我修改他们没有Spring运行。你有什么主意吗？

这是准备sessionFactory的代码：

@Configuration
@Transactional
@EnableTransactionManagement
@ComponentScan({ "com.company" })
public class HibernateInitializator {

    public SessionFactory getSessionFactory() {

        Properties hibernateProperties = getHibernateProperties();
        DataSource dataSource = getDatasourceConfiguration();
        LocalSessionFactoryBean localSessionFactoryBean = generateSessionFactoryBean(new String[] { "com.company" },
            dataSource, hibernateProperties);
        SessionFactory sessionFactory = localSessionFactoryBean.getObject();

        HibernateTransactionManager txManager = new HibernateTransactionManager();
        txManager.setSessionFactory(sessionFactory);

        return sessionFactory;
    }

    private DataSource getDatasourceConfiguration() {

        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost:3306/dbName");
        dataSource.setUsername("username");
        dataSource.setPassword("password");

        return dataSource;
    }

    private static LocalSessionFactoryBean generateSessionFactoryBean(String[] basePackage, DataSource dataSource,
        Properties hibernateProperties) {

        LocalSessionFactoryBean localSessionFactoryBean = new LocalSessionFactoryBean();
        localSessionFactoryBean.setDataSource(dataSource);
        localSessionFactoryBean.setPackagesToScan(basePackage);
        localSessionFactoryBean.setHibernateProperties(hibernateProperties);

        return localSessionFactoryBean;
    }

    private static Properties getHibernateProperties() {

        Properties hibernateProperties = new Properties();
        hibernateProperties.put("hibernate.dialect", "org.hibernate.dialect.MySQL5InnoDBDialect");
        hibernateProperties.put("hibernate.show_sql", false);
        hibernateProperties.put("hibernate.generate_statistics", false);
        hibernateProperties.put("hibernate.hbm2ddl.auto", "update");
        hibernateProperties.put("hibernate.use_sql_comments", false);

        return hibernateProperties;
    }
}

这是一个使用它的简单测试类：

public class GenericDAOHibernateTest {

    private GenericDAOHibernate dao;

    @BeforeTest
    private void testInitialization() {

        dao = new GenericDAO();
        HibernateInitializator initializator = new HibernateInitializator();
        SessionFactory sessionFactory = initializator.getSessionFactory();
        dao.setSessionFactory(sessionFactory);
    }

    @Test(description = "Checks that returns the user list ")
    public void shouldReturnsUserList() throws SQLException, Exception {

        List<Object[]> openResultSetList = dao.doSomeOperation();
        ...
    }
}
