Question

我有一个班级：

    public class ProductComercialOrderDAO  extends BaseDao implements ProductComercialOrderDAOLocal  {

    private final static Logger log = UtilsBusiness.getLog4J(ProductComercialOrderDAO.class);

    public Session getSession() throws DAOServiceException{
        return super.getSession();
    }

    @Override
    @TransactionAttribute(TransactionAttributeType.REQUIRED)
    public void createProductComertialOrder(ProductComertialOrder pcom) throws DAOServiceException, DAOSQLException {

        log.debug("== Init createProductComertialOrder/ProductComercialOrderDAO ==");
        Session session = this.getSession();
        try {
            session.save(pcom);
            this.doFlush(session);
        } catch (Throwable ex) {
            log.error("== Exception in ProductComertialOrder ==");
            throw super.manageException(ex);
        } finally {
            log.debug("== createProductComertialOrder/ProductComercialOrderDAO End ==");
        }

    }
}

我需要嘲笑方法：

public Session getSession() throws DAOServiceException{
    return super.getSession();
}

用于在jUnit测试阶段替换Hibernate数据源。

我和Mockito有这个代码：

package dao;

import static org.junit.Assert.assertEquals;
import static org.mockito.Mockito.when;

import java.util.Date;

import javax.ejb.EJB;

import org.hibernate.SessionFactory;
import org.hibernate.classic.Session;
import org.junit.After;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;

import co.com.myapp.sdii.exceptions.DAOSQLException;
import co.com.myapp.sdii.exceptions.DAOServiceException;
import co.com.myapp.sdii.model.pojo.ProductComercialOrder;
import co.com.myapp.sdii.persistence.dao.core.impl.ProductComercialOrderDAO;
import co.com.myapp.sdii.persistence.hibernate.HibernateUtil;

public class ProductComercialOrderDAOTest {

    public ProductComercialOrderDAO prodcomDao;

    private ProductComercialOrder prodCom;
    SessionFactory sessionFact = null;
    Session session = null;


    @Test
    public void setUp() throws DAOServiceException, DAOSQLException{
        sessionFact = util.HibernateUtil.getSessionFactory();
        sessionFact.openSession();
        session = sessionFact.getCurrentSession();

        prodCom = new ProductComercialOrder();
        prodCom.setCreationDate(new Date());
        prodCom.setCreationUser("user1");
        prodCom.setId(1L);
        prodCom.setPrdCategory("Hardware");
        prodCom.setPrdCategoryType("IRD");
        prodCom.setOrderNum(1L);

        if(prodcomDao == null){
            prodcomDao = new ProductComercialOrderDAO();
        }

        Mockito.spy(ProductComercialOrder.class);
        Mockito.when(prodcomDao.getSession()).thenReturn(session);
        prodcomDao.createProductComercialOrder(prodCom);        
    }


}

但是当我打电话时：

prodcomDao.createProductComercialOrder(prodCom);

调用原始ProductComercialOrderDAO.getSession()，而不是我的模拟。

如何模拟替换hibernate会话的方法？

Answer 1

你需要这样做 Mockito.doReturn(session).when(prodcomDao).getSession() 确保不调用原始方法。

请参阅@ akcasoy的回答Mockito - difference between doReturn() and when()

Mockito替换方法
