项目架子：servlet+spring+hibernate+oracle
那个Action大致是这样的，这里面涉及到两个数据的插入，一个是merchantDAO.save(merchant);一个是userDAO.save(user);我想用spring事务控制，如果user插入失败，则之前插入的merchant回滚，我试了试，没实现，估计是我配置文件没写对。

package action.merchant;

public class AddMerchantAction extends HttpServlet {

 

 public void doPost(HttpServletRequest request, HttpServletResponse response)

   throws ServletException, IOException {

  

  ApplicationContext ctx = SpringInitListener.getCtx();

 

   //添加商户

  MerchantInfoDAO merchantDAO = MerchantInfoDAO.getFromApplicationContext(ctx);

  MerchantInfo merchant = new MerchantInfo();

    

  merchantDAO.save(merchant);

  

  //添加User

  UserInfoDAO userDAO = UserInfoDAO.getFromApplicationContext(ctx);

  UserInfo user = new UserInfo();

  userDAO.save(user);

   

 }

}

配置文件代码大致如下：
