在spring4中应用Annotation驱动的Jdbc-transaction

Question

我正在尝试在我的spring mvc项目中定义事务，但遇到问题：

// xml文件

 </beans>

//这是我想要应用交易的类

public class CustomerOrderAdapter 
{
    public void displayCustomerOrder(String mobileNo) 
    {     }

    @Transactional(propagation = Propagation.REQUIRED, isolation = Isolation.DEFAULT, readOnly = true)  
    public Map<String, Object> createCustomerOrderData(SalesCommandObject salesCommandObject,long OrderForDelete) throws Exception
    {
        Map <String, Object> data = new HashMap<String, Object>();  
    try
        {
                salesDaoImpl.deleteSalesitems(OrderNo);
                salesDaoImpl.deleteSales(OrderNo);
                             salesDaoImpl.insertSalesItems(updatedOn,OrderNo,CustmobileNo);

salesDaoImpl.insertSales(totalSale, SlotNo, OrderNo);

        }
        catch(IndexOutOfBoundsException ex)
        {
            System.out.println("No Record to Save");    
            data.put("status", "No Record to Save");
        }
        catch(Exception e)
        {
            System.out.println(e.toString());
            data.put("status", e);
        }
        data.put("status", "Purchase Successfull");
        return data;
    }

}
