这分别是我的hbm和测试代码。我正在使用Spring的HibernateTemplate。我不使用DAO。使用Spring 2.0.7的Hibernate
2.2.5

<class name="Product" table="PRODUCT">

测试

public class ProductTest extends HibernateTestCase
{
    @Test
    public void save()
    {
        // Level 1 - mortgage LOB
        Product mortgage = new Product();
        mortgage.setCode("Mortgage");

        Product ml = new Product();
        ml.setCode("Mortgage Loan");

        Product me = new Product();
        me.setCode("Home Equity LOC");

        mortgage.addChild(ml);
        // mortgage.addChild(me);

        hibernateTemplate.save(mortgage);
    }

    @Override
    public List<String> getHbmResourceUnderTest()
    {
        return Lists.newArrayList("Product.hbm.xml");
    }
}

超级测试班

public abstract class HibernateTestCase

    protected HibernateTemplate hibernateTemplate;

    protected TransactionTemplate transTemplate;

    public TransactionTemplate getTransTemplate()
    {
        return transTemplate;
    }

    protected PlatformTransactionManager transactionManager;

    @Before

        for (String resource : getHbmResourceUnderTest())

        SessionFactory sessionFactory = configuration.buildSessionFactory();

        transactionManager = new HibernateTransactionManager(sessionFactory);
        hibernateTemplate = new HibernateTemplate(sessionFactory);
        transTemplate = new TransactionTemplate(transactionManager);
    }

    public abstract List<String> getHbmResourceUnderTest();
}
