spring+hibernate單元測試案例

1,maven創建web工程

2,導入相關依賴 pom.xml

4,寫dao層和實現類

import java.util.List;
import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.orm.hibernate4.HibernateCallback;
import org.springframework.orm.hibernate4.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
/***
 * hibernate基礎實現類
 * @author 
 *
 * @param <T>
 */


@Repository
public class BaseDao<T> extends HibernateDaoSupport {
    
    @Autowired()
    @Qualifier("sessionFactory")
    public void setBaseSessionFactory(SessionFactory sessionFactory) {
        super.setSessionFactory(sessionFactory);
    }
    
  protected    List<T> getList(final String entityName, final int beginIndex,final int length){
        
      return this.getHibernateTemplate().execute(new HibernateCallback<List<T>>() {

            @Override
            public List<T> doInHibernate(Session session) throws HibernateException {
            final    String hql=" from "+entityName;
                Query query=session.createQuery(hql);
                query.setFirstResult(beginIndex);
                query.setMaxResults(length);                
                @SuppressWarnings("unchecked")
                List<T> list=query.list();
                return list;
            }
            
        });
    }
    
    
}

import java.util.List;
import org.springframework.stereotype.Repository;
import com.test.entity.Goods;
@Repository
public interface GoodsDao {
    public  List<Goods> getList();
}

import java.util.List;
import org.springframework.stereotype.Repository;
import com.test.dao.GoodsDao;
import com.test.entity.Goods;
@Repository
public class GoodsDaoImpl extends BaseDao<Goods> implements GoodsDao {
    @Override
    public List<Goods> getList() {        
        return this.getList("Goods", 0, 1);
    }

}

5,service和實現類

import java.util.List;
import org.springframework.stereotype.Service;
import com.test.entity.Goods;
@Service
public interface GoodsService {
    public List<Goods> getList();
}

import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.test.dao.GoodsDao;
import com.test.entity.Goods;
import com.test.service.GoodsService;
@Service
public class GoodsServiceImpl implements GoodsService {
    
    @Autowired
    private GoodsDao goodsDao;
    @Override
    public List<Goods> getList() {
        // TODO Auto-generated method stub
        return goodsDao.getList();
    }

}

6,測試

import java.util.List;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;

import com.test.entity.Goods;
import com.test.service.GoodsService;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:applicationContext.xml" })
@Transactional
public class GoodsTest {
    @Autowired
    private GoodsService goodsService;
    
    @org.junit.Test
    public void getList() {
        List<Goods> goods=goodsService.getList();
        for(Goods g:goods) {
            System.out.println(g.getName());
        }
        
    }

}

 注：在單元測試插入數據時，默認會將事務回滾，如果想阻止spring transactional回滾，在test方法上加注解@Rollback（false）即可
