急急急！HibernateTemplate的update锁数据表问题

michaelliuyang 2011-07-22 11:30:56

我自己的action如果继承action类，去update表，就没有问题，事务可以正常提交。如果自己的action继承了dispatchAction，然后再去update，就产生了数据表被锁死的问题，数据也更新不成功，请教各个大侠这个问题是什么情况。
代码如下：



dao类

package com.dao;



import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.entity.Orders;



public class OrdersDao extends HibernateDaoSupport{

	

	@SuppressWarnings("unchecked")

	public List<Orders> getAllOrders(){

		return this.getHibernateTemplate().find("from Orders as o");

	}

	

	public void update(Orders order){

		this.getHibernateTemplate().update(order);

	}

	

	public void delete(int id) {

		

	}

	

	public Orders getOrderById(int id){

		return this.getHibernateTemplate().get(Orders.class, id);

	}

}

action类

package com.action;



import java.sql.Date;

import java.util.List;



import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;



import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;

import org.apache.struts.actions.DispatchAction;

import org.springframework.transaction.annotation.Propagation;

import org.springframework.transaction.annotation.Transactional;



import com.entity.Orders;

import com.service.OrdersService;



@Transactional(propagation=Propagation.REQUIRED)

public class OrdersAction extends DispatchAction {

	private OrdersService ordersService;



	public OrdersService getOrdersService() {

		return ordersService;

	}



	public void setOrdersService(OrdersService ordersService) {

		this.ordersService = ordersService;

	}



	public ActionForward list(ActionMapping mapping, ActionForm form,

			HttpServletRequest request, HttpServletResponse response) {

		List<Orders> orders = this.ordersService.getOrders();

		request.setAttribute("orders", orders);

		return mapping.findForward("list");

	}

	

	public ActionForward update(ActionMapping mapping, ActionForm form,

			HttpServletRequest request, HttpServletResponse response) {

		Orders or = ordersService.getOrderById(1);

		or.setCustName("yy1");

		this.ordersService.updateUser(or);

		return null;

	}

}
